[Impact]
* bcache-tools udev created symlinks might disappear when other udev
events are processed for the same devices.
* after mkfs.XXX in /dev/bcacheY you might face a condition where
/dev/bcache/by-{uuid,label}/zzz symlinks are gone.
* /dev/bcache/by-{uuid,label}/ symlinks are important so bcache
devices can be addressed by their UUIDs and not the ordering they were
assembled (MAAS depends on this feature, for example).
* it was also discussed in this bug that systemd-udev should *not*
populate /dev/disk/by-uuid/ with symlinks of disks that were bcache
backing devices. this was turned into a discussion whether blkid
should report those or not, and this discussion "died" after sometime.
This last item is what the systemd update is all about: to disallow
/dev/disk/by-XXX/ creation for bcache backing devices (a simple
change that will reduce end users confusion).
[Test Case]
* The reproducer script is here:
https://paste.ubuntu.com/p/37KGy2Smnp/
* Bionic can't reproduce the issue with the 18.04 kernel, nor with
the HWE kernel. Nevertheless, it is preferable that Bionic also do the
same thing: to read bcache superblock and feed environment for
/dev/bcache/by-{uuid,label} symlinks creation.
specifically for the verification for systemd, the above script can be
used, and then check that the bcache uuid symlink isn't present at
/dev/disk/by-uuid; for example, after running the above reproducer
script:
root@lp1861941-f:~# ls -l /dev/bcache/by-uuid/

Thanks!
[Impact]
* bcache-tools udev created symlinks might disappear when other udev
events are processed for the same devices.
* after mkfs.XXX in /dev/bcacheY you might face a condition where
/dev/bcache/by-{uuid,label}/zzz symlinks are gone.
* /dev/bcache/by-{uuid,label}/ symlinks are important so bcache
devices can be addressed by their UUIDs and not the ordering they were
assembled (MAAS depends on this feature, for example).
* it was also discussed in this bug that systemd-udev should *not*
populate /dev/disk/by-uuid/ with symlinks of disks that were bcache
backing devices. this was turned into a discussion whether blkid
should report those or not, and this discussion "died" after sometime.
This last item is what the systemd update is all about: to disallow
/dev/disk/by-XXX/ creation for bcache backing devices (a simple
change that will reduce end users confusion).
[Test Case]
* The reproducer script is here:
https://paste.ubuntu.com/p/37KGy2Smnp/
* Bionic can't reproduce the issue with the 18.04 kernel, nor with
the HWE kernel. Nevertheless, it is preferable that Bionic also do the
same thing: to read bcache superblock and feed environment for
/dev/bcache/by-{uuid,label} symlinks creation.
[Regression Potential]
* We are not depending on bcache device udev events any more when
creating the /dev/bcache/by-{uuid,label}/ symlinks. Instead

so we don't need to worry on Breaks/Conflicts in between the kernel
package and bcache-tools (and udev)).
* Long story short: kernel will continue to emit bcache udev events
as it did previously but now those events won't be used by anything -
after installing this SRU - because udev wrapper script is doing this
job (and doing it properly)

Hello Ryan, or anyone else affected,
Accepted bcache-tools into bionic-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/bcache-
tools/1.0.8-2ubuntu0.18.04.1 in a few hours, and then in the -proposed
repository.
Please help us by testing this new package. See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed. Your feedback will aid us getting this
update out to other Ubuntu users.
If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. In either case, without details of your testing we will
not be able to proceed.
Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance for helping!
N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
SRU TEAM: The last 2 commits show a summary for the merges/changes
I added some specific (to Bionic) notes in the template.
Thanks!
[Impact]
* bcache-tools udev created symlinks might disappear when other udev
events are processed for the same devices.
* after mkfs.XXX in /dev/bcacheY you might face a condition where
/dev/bcache/by-{uuid,label}/zzz symlinks are gone.
* /dev/bcache/by-{uuid,label}/ symlinks are important so bcache
devices can be addressed by their UUIDs and not the ordering they were
assembled (MAAS depends on this feature, for example).
* it was also discussed in this bug that systemd-udev should *not*
populate /dev/disk/by-uuid/ with symlinks of disks that were bcache
backing devices. this was turned into a discussion whether blkid
should report those or not, and this discussion "died" after sometime.
This last item is what the systemd update is all about: to disallow
/dev/disk/by-XXX/ creation for bcache backing devices (a simple
change that will reduce end users confusion).
[Test Case]
* The reproducer script is here:
https://paste.ubuntu.com/p/37KGy2Smnp/
* Bionic can't reproduce the issue with the 18.04 kernel, nor with
the HWE kernel. Nevertheless, it is preferable that Bionic also do the
same thing: to read bcache superblock and feed environment for
/dev/bcache/by-{uuid,label} symlinks creation.
[Regression Potential]
* We are not depending on bcache device udev events any more when
creating the /dev/bcache/by-{uuid,label}/ symlinks. Instead, we are
depending on a wrapper script that heads bcache device superblock. If
there is a bug in this wrapper the symlinks wouldn't work.
* Previously we were thinking in asking the kernel team to remove the
bcache udev event delta script they've done for previous case (LP:
#1729145). It creates the udev events that were being read and filling
the symlinks. We decided not to remove those (just from Groovy and on)
so we don't need to worry on Breaks/Conflicts in between the kernel
package and bcache-tools (and udev)).
* Long story short: kernel will continue to emit bcache udev events
as it did previously but now those events won't be used by anything -
after installing this SRU - because udev wrapper script is doing this
job (and doing it properly)

SRU TEAM:
Summary is the one above. The reason why Bionic SRU makes sense was
discussed with @paelzer during merge review:
https://code.launchpad.net/~rafaeldtinoco/ubuntu/+source/bcache-

Thanks for reviewing the SRU.

[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0
Just spoke to @ddstreet about the SYSTEMD-UDEV merges. We are discussing if we should keep the udev delta (from upstream) or not, considering that the issue will be already fixed by bcache-tools and udev change would only serve not to have backing devices at /dev/disk/by-uuid and /dev/disk/by-label (good for end user, but to add burden to ubuntu- devel). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1861941 Title: bcache by-uuid links disappear after mounting bcache0 Status in bcache-tools package in Ubuntu: In Progress Status in systemd package in Ubuntu: Fix Released Status in bcache-tools source package in Bionic: In Progress Status in systemd source package in Bionic: In Progress Status in bcache-tools source package in Focal: In Progress Status in systemd source package in Focal: In Progress Bug description: 1. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 2. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 root@ubuntu:~# apt-cache policy linux-image-virtual linux-image-virtual: Installed: 5.4.0.12.15 Candidate: 5.4.0.12.15 Version table: *** 5.4.0.12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status root@ubuntu:~# apt-cache policy linux-image-5.4.0-12-generic linux-image-5.4.0-12-generic: Installed: 5.4.0-12.15 Candidate: 5.4.0-12.15 Version table: *** 5.4.0-12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status 3. mount /dev/bcache0 && ls -al /dev/bcache/by-uuid/ + ls -al /dev/bcache/by-uuid/ total 0 drwxr-xr-x 2 root root 60 Feb 4 23:31 . drwxr-xr-x 3 root root 60 Feb 4 23:31 .. lrwxrwxrwx 1 root root 13 Feb 4 23:31 abdfd1f6-44ce-4266-91db-24667b9ae51a -> ../../bcache0 4. root@ubuntu:~# ls -al /dev/bcache/by-uuid ls: cannot access '/dev/bcache/by-uuid': No such file or directory ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-12-generic 5.4.0-12.15 ProcVersionSignature: Ubuntu 5.4.0-12.15-generic 5.4.8 Uname: Linux 5.4.0-12-generic x86_64 ApportVersion: 2.20.11-0ubuntu16 Architecture: amd64 Date: Tue Feb 4 23:31:52 2020 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: linux-signed-5.4 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1861941/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp

[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0
About blkid fix: Ryan has explained carefully how to obtain FS UUID from
the backing device at:
https://github.com/systemd/systemd/pull/16317#issuecomment-655574875
and about bcache-export-cached wrapper he created for simulating
CACHED_UUID and CACHED_LABEL (at 69-bcache.rules) and to create
/dev/bcache/{by-uuid,by-label}/{CACHED_UUID,CACHED_LABEL} symlinks.
He explained that having /dev/bcache/{by-uuid,by-label} is mandatory to
maintain same names for multiple bcache'd environments over reboots.
Currently, with the bcache-export-cached fix applied, it is *not*
mandatory to have systemd-udev fix to correctly create bcache symlinks
(or not) at /dev/disk/{by-uuid,by-label}: libblkid could have more
information regarding bcache backing devices, but judging by upstream
developers disposition they don't seem too worried about having that
feature since ID_FS_TYPE=bcache is already provided. (So, having
/dev/disk/by-uuid/XXX pointing to bcache backing devices would continue
happening...)
Summary:
Having the bcache-tools fix is enough for this bug (LP: #1861941) and
there could be changes to systemd-udev (I doubt judging by discussions
at https://github.com/systemd/systemd/pull/16317), or libblkid, that
could provide more information regarding bcache device types. If those
changes happen, we would need to revisit this bug.
IMHO,
I like the "skip_bcache_fs_type" approach done by Ryan to systemd-udev.
I'll maintain that as a delta to udev until
https://github.com/systemd/systemd/pull/16317 is fixed (if ever).
So, for now, PPA contains fix for bcache-tools for Groovy and Focal (and
will for Bionic) and that is enough to make /dev/bcache/XXX to work and
be stable after reboots. I'll keep the udev fix for Groovy and SRU that
fix for Focal and Bionic and upload to the PPA as well.
After all that is done, I'll tell kernel team to revert the bcache patch
on Bionic, Focal and Groovy kernels since it is not needed and will
reduce their delta and reduce chances of regressions over time.

TODOs (currently being started): 1 - adjust/add bcache-tools patch to use bcache-super-show (full path) (bcache-tools - bionic | focal | groovy) 1.1 - Ubuntu kernel patches for CACHED UUID resubmission could be removed (linux - bionic | focal | groovy) IF (1) is done and SRU'ed 1.2 - Work with upstream so they merge @raharper's patch 2 - drop systemd patch for /dev/disk/by-uuid | /dev/bcache/by-uuid ?? (systemd - bionic | focal | groovy) - I prefer to keep this patch and open upstream discussion for (3) 3 - blkid should not report FS_UUID for bcache backing devices (not a filesytem) (blkid - bionic | focal | groovy) - would avoid useless dev/disk/by-uuid, just like the systemd patch - blkid would have to be SRUed to all or systemd patch kept - will drive upstream discussion 4 - provide a temporary PPA with all fixes before SRU happens (MAAS tests) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1861941 Title: bcache by-uuid links disappear after mounting bcache0 Status in bcache-tools package in Ubuntu: Fix Released Status in systemd package in Ubuntu: Fix Released Status in bcache-tools source package in Bionic: Triaged Status in systemd source package in Bionic: Triaged Status in bcache-tools source package in Focal: Confirmed Status in systemd source package in Focal: Triaged Bug description: 1. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 2. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 root@ubuntu:~# apt-cache policy linux-image-virtual linux-image-virtual: Installed: 5.4.0.12.15 Candidate: 5.4.0.12.15 Version table: *** 5.4.0.12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status root@ubuntu:~# apt-cache policy linux-image-5.4.0-12-generic linux-image-5.4.0-12-generic: Installed: 5.4.0-12.15 Candidate: 5.4.0-12.15 Version table: *** 5.4.0-12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status 3. mount /dev/bcache0 && ls -al /dev/bcache/by-uuid/ + ls -al /dev/bcache/by-uuid/ total 0 drwxr-xr-x 2 root root 60 Feb 4 23:31 . drwxr-xr-x 3 root root 60 Feb 4 23:31 .. lrwxrwxrwx 1 root root 13 Feb 4 23:31 abdfd1f6-44ce-4266-91db-24667b9ae51a -> ../../bcache0 4. root@ubuntu:~# ls -al /dev/bcache/by-uuid ls: cannot access '/dev/bcache/by-uuid': No such file or directory ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-12-generic 5.4.0-12.15 ProcVersionSignature: Ubuntu 5.4.0-12.15-generic 5.4.8 Uname: Linux 5.4.0-12-generic x86_64 ApportVersion: 2.20.11-0ubuntu16 Architecture: amd64 Date: Tue Feb 4 23:31:52 2020 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: linux-signed-5.4 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1861941/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp

@Rafael It's in both places: https://github.com/koverstreet/bcache-tools/pull/1 I can update the PR there as well; though I don't think upstream cares as Kent's working on bcachefs instead of bcache AFAICT. > I see that you are trying to come up with something nor relying in the kernel fix (to throw the variables again after pivot root, etc..) I think after the systemd discussion upstream: https://github.com/systemd/systemd/pull/16317 The kernel uevent for CACHED_UUID isn't the right way to go long term; all of the information we want is present in the superblock of the devices as they are probed; If we have a 69-bcache.rules with a helper that uses bcache-super-show; we could drop the Ubuntu sauce patch we have; it's just noise (and now it's somewhat unreliable, this bug shows that). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1861941 Title: bcache by-uuid links disappear after mounting bcache0 Status in bcache-tools package in Ubuntu: Fix Released Status in systemd package in Ubuntu: Fix Released Status in bcache-tools source package in Bionic: Triaged Status in systemd source package in Bionic: Triaged Status in bcache-tools source package in Focal: Confirmed Status in systemd source package in Focal: Triaged Bug description: 1. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 2. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 root@ubuntu:~# apt-cache policy linux-image-virtual linux-image-virtual: Installed: 5.4.0.12.15 Candidate: 5.4.0.12.15 Version table: *** 5.4.0.12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status root@ubuntu:~# apt-cache policy linux-image-5.4.0-12-generic linux-image-5.4.0-12-generic: Installed: 5.4.0-12.15 Candidate: 5.4.0-12.15 Version table: *** 5.4.0-12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status 3. mount /dev/bcache0 && ls -al /dev/bcache/by-uuid/ + ls -al /dev/bcache/by-uuid/ total 0 drwxr-xr-x 2 root root 60 Feb 4 23:31 . drwxr-xr-x 3 root root 60 Feb 4 23:31 .. lrwxrwxrwx 1 root root 13 Feb 4 23:31 abdfd1f6-44ce-4266-91db-24667b9ae51a -> ../../bcache0 4. root@ubuntu:~# ls -al /dev/bcache/by-uuid ls: cannot access '/dev/bcache/by-uuid': No such file or directory ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-12-generic 5.4.0-12.15 ProcVersionSignature: Ubuntu 5.4.0-12.15-generic 5.4.8 Uname: Linux 5.4.0-12-generic x86_64 ApportVersion: 2.20.11-0ubuntu16 Architecture: amd64 Date: Tue Feb 4 23:31:52 2020 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: linux-signed-5.4 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1861941/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp

Status from old attempts to solve same nature issues:
Older (2018) merge request from @raharper:
https://github.com/koverstreet/bcache-tools/pull/1
addressing the fact that kernel uevents would not always emit
CACHED_UUID parameters, making udev to delete (whenever that happens)

This last MR pointed to previous related bugs:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=890446

I'm having similar issues to this bug and those described by Dmitrii in https://bugs.launchpad.net/charm-ceph-osd/+bug/1883585 specifically comment #2 and the last comment. It appears that if I run 'udevadm trigger --subsystem-match=block', I get my by-dname devices for bcaches, but if I run udevadm trigger w/out a subsystem match, something is triggering later than the block subsystem that is removing the links. Here are the runs with --verbose to show what appears to be getting probed on each run: https://pastebin.ubuntu.com/p/VPvSKRfGt4/ This is with 5.3.0-62 kernel on Bionic.

[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0
Ok, I'm going to revert this from the queued-up focal commits before uploading, as IIUC the /dev/disk/by-uuid/ symlink shouldn't actually matter, since the symlink that should be used is /dev/bcache/by-uuid/. And based on comment 47 it sounds like that's accurate, and the real fix needs to go into bcache-utils to properly create the dev/bcache/by-uuid/ symlink. This can be added back to the focal queue if I've misread the patch. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1861941 Title: bcache by-uuid links disappear after mounting bcache0 Status in bcache-tools package in Ubuntu: Triaged Status in linux package in Ubuntu: Incomplete Status in linux-signed package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Fix Released Status in bcache-tools source package in Bionic: New Status in linux source package in Bionic: New Status in linux-signed source package in Bionic: New Status in systemd source package in Bionic: New Status in bcache-tools source package in Focal: Confirmed Status in linux source package in Focal: Invalid Status in linux-signed source package in Focal: Confirmed Status in systemd source package in Focal: Confirmed Status in bcache-tools source package in Groovy: Triaged Status in linux source package in Groovy: Incomplete Status in linux-signed source package in Groovy: Confirmed Status in systemd source package in Groovy: Fix Released Bug description: 1. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 2. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 root@ubuntu:~# apt-cache policy linux-image-virtual linux-image-virtual: Installed: 5.4.0.12.15 Candidate: 5.4.0.12.15 Version table: *** 5.4.0.12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status root@ubuntu:~# apt-cache policy linux-image-5.4.0-12-generic linux-image-5.4.0-12-generic: Installed: 5.4.0-12.15 Candidate: 5.4.0-12.15 Version table: *** 5.4.0-12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status 3. mount /dev/bcache0 && ls -al /dev/bcache/by-uuid/ + ls -al /dev/bcache/by-uuid/ total 0 drwxr-xr-x 2 root root 60 Feb 4 23:31 . drwxr-xr-x 3 root root 60 Feb 4 23:31 .. lrwxrwxrwx 1 root root 13 Feb 4 23:31 abdfd1f6-44ce-4266-91db-24667b9ae51a -> ../../bcache0 4. root@ubuntu:~# ls -al /dev/bcache/by-uuid ls: cannot access '/dev/bcache/by-uuid': No such file or directory ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-12-generic 5.4.0-12.15 ProcVersionSignature: Ubuntu 5.4.0-12.15-generic 5.4.8 Uname: Linux 5.4.0-12-generic x86_64 ApportVersion: 2.20.11-0ubuntu16 Architecture: amd64 Date: Tue Feb 4 23:31:52 2020 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: linux-signed-5.4 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1861941/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0
@ddstreet I'm not sure where upstream is going just yet. For Ubuntu; I think 1) Adjusting the bcache-tools patch to use the full path to bcache- super-show should change; 2) If we fix (1) then I think we can drop the systemd patch from a bug fixing perspective; on the openSUSE image I did testing on; the skip of the dev/disk/by-uuid symlink for backing devices does not *break* the /dev/bcache/by-uuid ; it was missing due to the updated 69-bcache.rules not working. 3) IMO, blkid should not report FS_UUID for bcache backing/cache devices since it's not a Filesystem; we could patch that in blkid directly instead; alternatively since older blkid's may or maynot emit FS_UUID for bcache backing/caching devices the patch to systemd we're caring will avoid creating a useless dev/disk/by-uuid symlink to those devices. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1861941 Title: bcache by-uuid links disappear after mounting bcache0 Status in bcache-tools package in Ubuntu: Triaged Status in linux package in Ubuntu: Incomplete Status in linux-signed package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Fix Released Status in bcache-tools source package in Bionic: New Status in linux source package in Bionic: New Status in linux-signed source package in Bionic: New Status in systemd source package in Bionic: New Status in bcache-tools source package in Focal: Confirmed Status in linux source package in Focal: Invalid Status in linux-signed source package in Focal: Confirmed Status in systemd source package in Focal: Confirmed Status in bcache-tools source package in Groovy: Triaged Status in linux source package in Groovy: Incomplete Status in linux-signed source package in Groovy: Confirmed Status in systemd source package in Groovy: Fix Released Bug description: 1. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 2. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 root@ubuntu:~# apt-cache policy linux-image-virtual linux-image-virtual: Installed: 5.4.0.12.15 Candidate: 5.4.0.12.15 Version table: *** 5.4.0.12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status root@ubuntu:~# apt-cache policy linux-image-5.4.0-12-generic linux-image-5.4.0-12-generic: Installed: 5.4.0-12.15 Candidate: 5.4.0-12.15 Version table: *** 5.4.0-12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status 3. mount /dev/bcache0 && ls -al /dev/bcache/by-uuid/ + ls -al /dev/bcache/by-uuid/ total 0 drwxr-xr-x 2 root root 60 Feb 4 23:31 . drwxr-xr-x 3 root root 60 Feb 4 23:31 .. lrwxrwxrwx 1 root root 13 Feb 4 23:31 abdfd1f6-44ce-4266-91db-24667b9ae51a -> ../../bcache0 4. root@ubuntu:~# ls -al /dev/bcache/by-uuid ls: cannot access '/dev/bcache/by-uuid': No such file or directory ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-12-generic 5.4.0-12.15 ProcVersionSignature: Ubuntu 5.4.0-12.15-generic 5.4.8 Uname: Linux 5.4.0-12-generic x86_64 ApportVersion: 2.20.11-0ubuntu16 Architecture: amd64 Date: Tue Feb 4 23:31:52 2020 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: linux-signed-5.4 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1861941/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp

Also please update bcache-tools since it is Server Team's package and I also can't upload to Debian until the next keyring refresh. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1861941 Title: bcache by-uuid links disappear after mounting bcache0 Status in bcache-tools package in Ubuntu: Fix Released Status in linux package in Ubuntu: Incomplete Status in linux-signed package in Ubuntu: New Status in systemd package in Ubuntu: Invalid Status in bcache-tools source package in Focal: New Status in linux source package in Focal: Invalid Status in linux-signed source package in Focal: New Status in systemd source package in Focal: Invalid Status in bcache-tools source package in Groovy: Fix Released Status in linux source package in Groovy: Incomplete Status in linux-signed source package in Groovy: New Status in systemd source package in Groovy: Invalid Bug description: 1. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 2. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 root@ubuntu:~# apt-cache policy linux-image-virtual linux-image-virtual: Installed: 5.4.0.12.15 Candidate: 5.4.0.12.15 Version table: *** 5.4.0.12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status root@ubuntu:~# apt-cache policy linux-image-5.4.0-12-generic linux-image-5.4.0-12-generic: Installed: 5.4.0-12.15 Candidate: 5.4.0-12.15 Version table: *** 5.4.0-12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status 3. mount /dev/bcache0 && ls -al /dev/bcache/by-uuid/ + ls -al /dev/bcache/by-uuid/ total 0 drwxr-xr-x 2 root root 60 Feb 4 23:31 . drwxr-xr-x 3 root root 60 Feb 4 23:31 .. lrwxrwxrwx 1 root root 13 Feb 4 23:31 abdfd1f6-44ce-4266-91db-24667b9ae51a -> ../../bcache0 4. root@ubuntu:~# ls -al /dev/bcache/by-uuid ls: cannot access '/dev/bcache/by-uuid': No such file or directory ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-12-generic 5.4.0-12.15 ProcVersionSignature: Ubuntu 5.4.0-12.15-generic 5.4.8 Uname: Linux 5.4.0-12-generic x86_64 ApportVersion: 2.20.11-0ubuntu16 Architecture: amd64 Date: Tue Feb 4 23:31:52 2020 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: linux-signed-5.4 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1861941/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp

[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0
OK.
I've reviewed the kernel code, and there are no unexpected changes w.r.t
the CACHED_UUID change event. So I don't think we will need any kernel
changes which is good.
With the small change to the 60-persistent-storage.rules to not attempt
to create a /dev/disk/by-uuid symlink for the backing device; instead we
want to only create a /dev/bcache/by-uuid symlink to the bcacheN device
(that is associated with the backing device).
# by-label/by-uuid links (filesystem metadata), skip bcache backing,caching
devices, handled in 69-bcache.rules
ENV{ID_FS_TYPE}=="bcache", GOTO="skip_fs_uuid_enc"
ENV{ID_FS_USAGE}=="filesystem|other|crypto", ENV{ID_FS_UUID_ENC}=="?*",
SYMLINK+="disk/by-uuid/$env{ID_FS_UUID_ENC}"
ENV{ID_FS_USAGE}=="filesystem|other|crypto", ENV{ID_FS_LABEL_ENC}=="?*",
SYMLINK+="disk/by-label/$env{ID_FS_LABEL_ENC}"
LABEL="skip_fs_uuid_enc"
And then with my previously proposed changed to 69-bcache.rules in place
https://github.com/g2p/bcache-tools/pull/29/files
The test-case works just fine.

[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0
@Balint I do not thing the fix you're released is correct, can you upload a new version without the scripts? Also, we should fix make-bcache -B to ensure that cset.uuid is not initialized; that may be why the kernel thinks it should emit the CACHED_UUID if the suerpblock of the device has a cset.uuid value (versus None). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1861941 Title: bcache by-uuid links disappear after mounting bcache0 Status in bcache-tools package in Ubuntu: Fix Released Status in linux package in Ubuntu: New Status in linux-signed package in Ubuntu: New Status in systemd package in Ubuntu: Invalid Status in bcache-tools source package in Focal: New Status in linux source package in Focal: Invalid Status in linux-signed source package in Focal: New Status in systemd source package in Focal: Invalid Status in bcache-tools source package in Groovy: Fix Released Status in linux source package in Groovy: New Status in linux-signed source package in Groovy: New Status in systemd source package in Groovy: Invalid Bug description: 1. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 2. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 root@ubuntu:~# apt-cache policy linux-image-virtual linux-image-virtual: Installed: 5.4.0.12.15 Candidate: 5.4.0.12.15 Version table: *** 5.4.0.12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status root@ubuntu:~# apt-cache policy linux-image-5.4.0-12-generic linux-image-5.4.0-12-generic: Installed: 5.4.0-12.15 Candidate: 5.4.0-12.15 Version table: *** 5.4.0-12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status 3. mount /dev/bcache0 && ls -al /dev/bcache/by-uuid/ + ls -al /dev/bcache/by-uuid/ total 0 drwxr-xr-x 2 root root 60 Feb 4 23:31 . drwxr-xr-x 3 root root 60 Feb 4 23:31 .. lrwxrwxrwx 1 root root 13 Feb 4 23:31 abdfd1f6-44ce-4266-91db-24667b9ae51a -> ../../bcache0 4. root@ubuntu:~# ls -al /dev/bcache/by-uuid ls: cannot access '/dev/bcache/by-uuid': No such file or directory ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-12-generic 5.4.0-12.15 ProcVersionSignature: Ubuntu 5.4.0-12.15-generic 5.4.8 Uname: Linux 5.4.0-12-generic x86_64 ApportVersion: 2.20.11-0ubuntu16 Architecture: amd64 Date: Tue Feb 4 23:31:52 2020 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: linux-signed-5.4 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1861941/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0
Digging deeper and walking through this in a focal vm, I'm seeing some
strange things.
Starting with a clean disk, and just creating the backing device like
so:
make-bcache -B /dev/vdb
We see /dev/bcache0 get created with vdb as the backing device. Now,
after this, I see:
/dev/bcache/by-uuid/ -> ../../bcache0
This is unexpected. It should *only* appear once the bcache0 device is
actively cached; that is the bcache driver should not emit CACHED_UUID,
until the UUID is actually cached, which only happens once we've
registered a cache device with the bcache0 device. We need to look at
the kernel source to see if the SAUCE patch isn't quite right, or some
other part of bcache code has changed.
Next issue, blkid now detects the bcache dev.uuid, and this shows up
like so:
# udevadm test-builtin blkid /sys/class/block/vdb
...
vdb: Probe /dev/vdb with raid and offset=0
ID_FS_UUID=d7d7e025-b8d2-43cb-a5df-c240ba1418dc
ID_FS_UUID_ENC=d7d7e025-b8d2-43cb-a5df-c240ba1418dc
ID_FS_TYPE=bcache
ID_FS_USAGE=other
Note, it shows up as an FS_UUID, but it is *NOT* an fs_uuid; there is no
filesystem on this device at all at this time; it does have a bcache
superblock, note the FS_UUID matches the dev.uuid of the backing device.
# bcache-super-show /dev/vdb
sb.magicok
sb.first_sector 8 [match]
sb.csum 29D6774A332A280B [match]
sb.version 1 [backing device]
dev.label (empty)

dev.data.cache_state0 [detached]
cset.uuid 37b37bc1-e185-4825-8900-579df102b7d6
It's also curious that cset.uuid has a UUID, as there are no csets
created; IMO this is also a bug and it should be 0, null, or empty.
Now, here's where the udev fights over the links. The backing device,
vdb, triggers this rule in 60-persistent-storage.rules:
# by-label/by-uuid links (filesystem metadata)
ENV{ID_FS_USAGE}=="filesystem|other|crypto", ENV{ID_FS_UUID_ENC}=="?*",
SYMLINK+="disk/by-uuid/$env{ID_FS_UUID_ENC}"
This creates confusion due to the CACHED_UUID also being emitted from
the kernel, like so:
root@ubuntu:/run/udev/links# ls -al
/dev/disk/by-uuid/d7d7e025-b8d2-43cb-a5df-c240ba1418dc
lrwxrwxrwx 1 root root 9 May 21 16:39
/dev/disk/by-uuid/d7d7e025-b8d2-43cb-a5df-c240ba1418dc -> ../../vdb
root@ubuntu:/run/udev/links# ls -al
/dev/bcache/by-uuid/d7d7e025-b8d2-43cb-a5df-c240ba1418dc
lrwxrwxrwx 1 root root 13 May 21 16:39
/dev/bcache/by-uuid/d7d7e025-b8d2-43cb-a5df-c240ba1418dc -> ../../bcache0
There we have two devices both claiming the backing devices dev.uuid
value, with two different block names.
So, in summary, there are two problems to fix:
1) blkid on bcache devices should not report FS_UUID values when
FS_TYPE=bcache; there is no filesystem on it; this will need to be
discussed upstream
2) our kernel (need to check mainline vs. ours) emits CACHED_UUID when
the bcache0 is created, but no cache is attached: see this udev event:
KERNEL[2217.605118] change /devices/virtual/block/bcache0 (block)

[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0
That doesn't explain why they show up sometimes, but not all of the time. There are 3 devices in play here. * The backing device, let's say /dev/vda; this is where we want to store the data. * The caching device, let's say /dev/vdb; this holds the cache. * The bcache device; this only appears when a backing device is detected; via bcache-probe which reads the header on the disk and indicates it's a bcache device. Now, there are a few sequences that we see: 1) make-bcache -b /dev/vda -c /deb/vdb will create a bcache0 with the cache and backing dev at the same time and emit the CACHED_UUID change event which runs *after* 60-persistent-storage, and adds the bcache/by-uuid links 2) After a reboot (or if you tear down a bcache0 by stopping them in sysfs) we have several scenarios where the 2 real block devices are found: 2a) order: backing, bcacheN, caching In this scenario, vda will run through 60-persistent-storage.rules and blkid will discover ID_FS_TYPE=bcache, and generates only by-path, by-id links for the device, 69-bcache.rules will run bcache-register /dev/vda which informs the kernel that a backing device has been found. If the cache device has not yet been handled by udev (we don't know if a cache device exists, bcache can work without one) then the kernel will create a bcacheN device, but without the cache device being present, it will *NOT* emit a CHANGE event with CACHED_UUID value. Now when the cache device (vdb) is going through, 60-persistent-storage.rules, blkid will discover the same settings, TYPE=bcache, generate by-path, by-id symlinks. Then 69-bcache.rules runs, triggers a bcache-register on vdb registering the cache device in the kernel and because the superblock on the backing device specifies the cache device UUID it used the kernel can bind the cache device into the correct bcacheN device. A mainline kernel (no sauce patch) does not emit a CHANGE event with CACHED_UUID value. Our sauce patch changes the kernel to emit the CHANGE event with CACHED_UUID whenever we bind a cache device to an existing bcacheN precisely so the bcache/by-* links get generated. 2b) order: cache, backing, bcacheN Here, when vdb is plugged in, the cache device is registered in the kernel, but without a backing device, no bcacheN device is created yet. Then the backing is probed, as in 2a; the bcache-register command will register it with the kernel, and create a bcache0, and since the cache device is present, mainline kernels (and ours) will emit the CHANGE event with CACHED_UUID With this in-mind; it appears to me that in the focal case we're seeing the bcache driver CHANGE event with CACHED_UUID and then additional change events from the block layer around the bcache0 device (but not emitted from the bcache driver code) So I'd like to understand why ... I expect those events to occur but not before the driver change event. And maybe that's the race here The happy path: 1. udev processing CHANGE on backing device, it's bcache so we register it 2. kernel bcache driver creates a bcache0 block device (udev ADD event) 3. udev processing CHANGE on bcache0 device 4. udev processing CHANGE on cache device, it's bcache so we register it 5. kernel bcache driver emits CHANGE event with CACHED_UUID 6. udev processing CHANGE on bcache0 device with CACHED_UUID The bad path 1. udev processing CHANGE on cache device, it's bcache so we register it 2. udev processing CHANGE on backing device, it's bcache so we register it 3. kernel bcache driver creates a bcache0 block device (udev ADD event) 4. kernel bcache driver emits CHANGE event with CACHED_UUID 5. udev processing CHANGE on bcache0 device with CACHED_UUID 6. udev processing CHANGE on bcache0 device without CACHED_UUID if the bcache change event occurs before the block layer change events, then the database does get clobbered ... but we've an incomplete trace; we should see pairs of events, one from KERNEL, and then one from UDEV. We should definitely get a complete capture for this bug. w.r.t the fix; I've a few concerns: 1) bcache-keep-symlinks relies on /dev/bcache/by-* links to exist, if they are removed, then the keep won't work. 2) The removal of the /dev/bcache/by-uuid/ happens during processing of 60-persistent-storage.rules, which will remove the link before bcache-keep-symlinks can run (it's in 69-bcache.rules) 3) since we cannot rely on the existing links, instead we should read and parse the bcache superblock devices, much like the one I put together (and you reminded me I wrote) https://github.com/g2p/bcache-tools/pull/29/files -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1861941 Title: bcache by-uuid links disappear after mounting
[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0
@raharper To my understanding with the change action udev removes the DEVLINKS which are not still valid. Udev can't tell which links are still valid in cache/by-*. The only reason udev knows about the links is because the rule added them with SYMLINK+= when the dev was created and it is a sane assumption that when a change action appears with DEVLINKS only the new DEVLINKS are valid. Hence the fix. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1861941 Title: bcache by-uuid links disappear after mounting bcache0 Status in bcache-tools package in Ubuntu: Fix Released Status in linux package in Ubuntu: Invalid Status in linux-signed package in Ubuntu: Invalid Status in systemd package in Ubuntu: Invalid Status in bcache-tools source package in Focal: New Status in linux source package in Focal: Invalid Status in linux-signed source package in Focal: New Status in systemd source package in Focal: Invalid Status in bcache-tools source package in Groovy: Fix Released Status in linux source package in Groovy: Invalid Status in linux-signed source package in Groovy: Invalid Status in systemd source package in Groovy: Invalid Bug description: 1. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 2. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 root@ubuntu:~# apt-cache policy linux-image-virtual linux-image-virtual: Installed: 5.4.0.12.15 Candidate: 5.4.0.12.15 Version table: *** 5.4.0.12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status root@ubuntu:~# apt-cache policy linux-image-5.4.0-12-generic linux-image-5.4.0-12-generic: Installed: 5.4.0-12.15 Candidate: 5.4.0-12.15 Version table: *** 5.4.0-12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status 3. mount /dev/bcache0 && ls -al /dev/bcache/by-uuid/ + ls -al /dev/bcache/by-uuid/ total 0 drwxr-xr-x 2 root root 60 Feb 4 23:31 . drwxr-xr-x 3 root root 60 Feb 4 23:31 .. lrwxrwxrwx 1 root root 13 Feb 4 23:31 abdfd1f6-44ce-4266-91db-24667b9ae51a -> ../../bcache0 4. root@ubuntu:~# ls -al /dev/bcache/by-uuid ls: cannot access '/dev/bcache/by-uuid': No such file or directory ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-12-generic 5.4.0-12.15 ProcVersionSignature: Ubuntu 5.4.0-12.15-generic 5.4.8 Uname: Linux 5.4.0-12-generic x86_64 ApportVersion: 2.20.11-0ubuntu16 Architecture: amd64 Date: Tue Feb 4 23:31:52 2020 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: linux-signed-5.4 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1861941/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp

[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0
I guess I don't understand why we see this in focal. The two events in
Colin's trace always happen on any Ubuntu kernel. We should see if we
can get another udev trace on bionic that captures both CHANGE events,
one will be from the bcache driver itself, and one is from the block
layer. THe order and content of the change event matter.
Another thing I don't understand is why does udev drop the a symlink created by
another rule? This seems like the core issue.
Looking at systemd/udev source code; udev will do a
FOREACH_DEVICE_DEVLINK and check if the name is in the database file for
the device. Its not clear to me yet how or when the database file get's
written.
The other question I have is: if we reversed the order of the focal
CHANGE events, wouldn't we see just the opposite happen (the
driver=bcache change event would not have all of the devlinks from a
blkid probe) and all of the /dev/disk/by-{id, uuid, ...} get removed
when running
I think the patch you're proposing should work; but I don't think we've
root caused why the link gets removed in the first place. Once we
understand the root cause, I think we can better understand what a fix
should look like.
Lastly, I think we might also test this out on mainline kernel; I wonder if our
SAUCE patch for emitting the CACHED_UUID needs an update (or could be dropped).

[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0
The reason for udev cleaning up the links is that they are missing from the change event's DEVLINKS. Since bcache-tools manages those symlinks IMO it should keep them around. Please take a look at the attached patch, I'll upload it if it is OK. ** Patch added: "bcache-tools_1.0.8-3ubuntu1.patch" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1861941/+attachment/5374566/+files/bcache-tools_1.0.8-3ubuntu1.patch ** Also affects: bcache-tools (Ubuntu) Importance: Undecided Status: New ** Changed in: systemd (Ubuntu Focal) Status: New => Invalid ** Changed in: systemd (Ubuntu Groovy) Status: In Progress => Invalid ** Changed in: bcache-tools (Ubuntu Groovy) Importance: Undecided => High ** Changed in: bcache-tools (Ubuntu Groovy) Status: New => In Progress ** Changed in: linux (Ubuntu Groovy) Status: Incomplete => Invalid ** Changed in: linux (Ubuntu Focal) Status: New => Invalid ** Changed in: linux-signed (Ubuntu Groovy) Status: New => Invalid ** Changed in: bcache-tools (Ubuntu Groovy) Assignee: (unassigned) => Balint Reczey (rbalint) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1861941 Title: bcache by-uuid links disappear after mounting bcache0 Status in bcache-tools package in Ubuntu: In Progress Status in linux package in Ubuntu: Invalid Status in linux-signed package in Ubuntu: Invalid Status in systemd package in Ubuntu: Invalid Status in bcache-tools source package in Focal: New Status in linux source package in Focal: Invalid Status in linux-signed source package in Focal: New Status in systemd source package in Focal: Invalid Status in bcache-tools source package in Groovy: In Progress Status in linux source package in Groovy: Invalid Status in linux-signed source package in Groovy: Invalid Status in systemd source package in Groovy: Invalid Bug description: 1. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 2. root@ubuntu:~# lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 root@ubuntu:~# apt-cache policy linux-image-virtual linux-image-virtual: Installed: 5.4.0.12.15 Candidate: 5.4.0.12.15 Version table: *** 5.4.0.12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status root@ubuntu:~# apt-cache policy linux-image-5.4.0-12-generic linux-image-5.4.0-12-generic: Installed: 5.4.0-12.15 Candidate: 5.4.0-12.15 Version table: *** 5.4.0-12.15 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status 3. mount /dev/bcache0 && ls -al /dev/bcache/by-uuid/ + ls -al /dev/bcache/by-uuid/ total 0 drwxr-xr-x 2 root root 60 Feb 4 23:31 . drwxr-xr-x 3 root root 60 Feb 4 23:31 .. lrwxrwxrwx 1 root root 13 Feb 4 23:31 abdfd1f6-44ce-4266-91db-24667b9ae51a -> ../../bcache0 4. root@ubuntu:~# ls -al /dev/bcache/by-uuid ls: cannot access '/dev/bcache/by-uuid': No such file or directory ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-12-generic 5.4.0-12.15 ProcVersionSignature: Ubuntu 5.4.0-12.15-generic 5.4.8 Uname: Linux 5.4.0-12-generic x86_64 ApportVersion: 2.20.11-0ubuntu16 Architecture: amd64 Date: Tue Feb 4 23:31:52 2020 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: linux-signed-5.4 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1861941/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
