  [Impact]

  https://github.com/openzfs/zfs/issues/12462

  Ubuntu 20.04.2 LTS
  Kernel: 5.11.0-25-generic #27~20.04.1-Ubuntu
  zfs-0.8.3-1ubuntu12.12
  zfs-kmod-2.0.2-1ubuntu5

  Trying to run zfs send | receive and getting an error:

  # zfs send  'rpool/home'@'autosnap_2020-08-01_00:59:01_monthly' | zfs receive 
 -s -F 'nas/rpool_backup/home'
  cannot receive: failed to read from stream
  cannot receive new filesystem stream: dataset does not exist

  This used to work before the recent Ubuntu kernel update from 5.8 to 5.11
  Kernel 5.8 came with zfs-kmod-0.8.4-1ubuntu11.2

  Ubuntu updates that broke it:

  Upgrade: linux-headers-generic-hwe-20.04:amd64 (5.8.0.63.71~20.04.45, 
5.11.0.25.27~20.04.10), linux-
  image-generic-hwe-20.04:amd64 (5.8.0.63.71~20.04.45, 5.11.0.25.27~20.04.10), 
linux-generic-hwe-20.04
  :amd64 (5.8.0.63.71~20.04.45, 5.11.0.25.27~20.04.10)

  Sending the zfs send part to a file works, but then sending the file
  to zfs receive also fails. The dump file size seems reasonable but the
  contents may not be correct.

  [Test Plan]

  1. create test pool and backup pool

  sudo zpool create pool /dev/vdb1
  sudo zpool create backup  /dev/vdc1

  2. populate pool with some files and create some snapshots

  sudo  zfs snapshot pool@now1

  create some more files etc, make another snapshot

  sudo  zfs snapshot pool@now2

  3. perform send/recv using -s option:

  sudo zfs send pool@now1 | sudo zfs receive -vFs backup
  sudo zfs send -i pool@now1 pool@now2 | sudo zfs receive -vFs backup

  Without the fix, the -s option on the receive fails. With the fix it
  works fine.  Test with focal 5.4 and 5.11 kernel to exercise 0.8.x and
  2.x kernel ZFS drivers.

  [Where problems could occur]

  The main fix nullifies the deprecated  action_handle option so that
  it's not checked, this allows 0.8.x userspace it to be forwardly
  compatible with 2.x kernel ZFS and also since it is deprecated in
  0.8.x it makes not difference to the 0.8.x kernel ZFS driver. Thus the
  risk with patch action_handle is very small.

  Included in the fix is a send/recv upstream bug fix 
4910-Fix-EIO-after-resuming-receive-of-new-dataset-over-a.patch that makes 
send/recv more resilient by making  zfs receive to always unmount and remount 
the
  destination, regardless of whether the stream is a new stream or a
  resumed stream.  The change is upstream for ~10 months and has minimal impact 
on current recv functionality.

2021-10-17 Thread Lyndon Lapierre
The bugfix has been working as expected over the past 3 days on my 2
systems:

Intel NUC (kernel 5.11.0-37-generic)
GCP Instance (kernel 5.11.0-1020-gcp)

None of my syncoid jobs have failed, I am no longer using the --no-
resume (-s) flag as a workaround.

2021-09-29 Thread ianrumford
Hello all,

Hope everyone is well and safe.

This is a plea to push along the resolution of this bug.

I'm heavily invested in zfs and this has been a huge problem for me.

Just like TimK I'm a sanoid/syncoid user and have seen the zfs recv
problem.  Changing syncoid's perl to not use "-s" worked for me. But
thats not been an end to my problems.

Originally I thought I had "lost" my main 10TB zpool for e.g hardware
reasons, but its not proved simple as that. I can import and read from
the zpool but see zfs timeouts regularly in syslog. If I try to write
to this pool it hangs. zfs list hangs as well. Eventually zfs seems
completely "stopped" and I have to reboot.

Assuming my "tank" was trashed, I had been using my (syncoid) backups
to reestablish my files in a new zfs pool on new hardware. Which
worked fine (+1 syncoid).

I've been trying to reestablish backups for my new pool/hardware this
morning and find whereas I can zfs send a 4.8GB snapshot ok, I can not
send a 7.2GB (or larger) snapshots - I get the rather anodyne message
"Input/output error".

I have also seen hangs when trying to zfs destroy snapshots on one of
my other pools. Whether the hanging destroy is the root cause or just
a casualty of other zfs stuff going on, I've no information.

I realise that relating the generally instability of my system is
pretty vague: its proving hard to pick apart the problems and
demonstrate repeatable effects.

So I'm eager to try the proposed fix but, as Jason has said, there is
no amd64 version yet in focal-proposed.

Can I encourage you to make the fix available please?

Really appreciate everybody's effort.

Thanks in advance.

  Ubuntu 20.04.2 LTS
  Kernel: 5.11.0-25-generic #27~20.04.1-Ubuntu
  zfs-0.8.3-1ubuntu12.12
  zfs-kmod-2.0.2-1ubuntu5

  Trying to run zfs send | receive and getting an error:

  # zfs send  'rpool/home'@'autosnap_2020-08-01_00:59:01_monthly' | zfs receive 
 -s -F 'nas/rpool_backup/home'
  cannot receive: failed to read from stream
  cannot receive new filesystem stream: dataset does not exist

  This used to work before the recent Ubuntu kernel update from 5.8 to 5.11
  Kernel 5.8 came with zfs-kmod-0.8.4-1ubuntu11.2

  Ubuntu updates that broke it:

  Upgrade: linux-headers-generic-hwe-20.04:amd64 (5.8.0.63.71~20.04.45, 
5.11.0.25.27~20.04.10), linux-
  image-generic-hwe-20.04:amd64 (5.8.0.63.71~20.04.45, 5.11.0.25.27~20.04.10), 
linux-generic-hwe-20.04
  :amd64 (5.8.0.63.71~20.04.45, 5.11.0.25.27~20.04.10)

  Sending the zfs send part to a file works, but then sending the file
  to zfs receive also fails. The dump file size seems reasonable but the
  contents may not be correct.

  [Test Plan]

  1. create test pool and backup pool

  sudo zpool create pool /dev/vdb1
  sudo zpool create backup  /dev/vdc1

  2. populate pool with some files and create some snapshots

  sudo  zfs snapshot pool@now1

  create some more files etc, make another snapshot

  sudo  zfs snapshot pool@now2

  3. perform send/recv using -s option:

  sudo zfs send pool@now1 | sudo zfs receive -vFs backup
  sudo zfs send -i pool@now1 pool@now2 | sudo zfs receive -vFs backup

  Without the fix, the -s option on the receive fails. With the fix it
  works fine.  Test with focal 5.4 and 5.11 kernel to exercise 0.8.x and
  2.x kernel ZFS drivers.

  [Where problems could occur]

  The main fix nullifies the deprecated  action_handle option so that
  it's not checked, this allows 0.8.x userspace it to be forwardly
  compatible with 2.x kernel ZFS and also since it is deprecated in
  0.8.x it makes not difference to the 0.8.x kernel ZFS driver. Thus the
  risk with patch action_handle is very small.

  Included in the fix is a send/recv upstream bug fix 
4910-Fix-EIO-after-resuming-receive-of-new-dataset-over-a.patch that makes 
send/recv more resilient by making  zfs receive to always unmount and remount 
the
  destination, regardless of whether the stream is a new stream or a
  resumed stream.  The change is upstream for ~10 months and has minimal impact 
on current recv functionality.

While hot-fixing the issue is fine, I feel like this won't be the last
bug like this we run into as long as we choose to mix-and-match
versions.

Wouldn't the better solution be adding HWE ZFS userland packages to
match the kernel module?

It seems the amd64 build failed and left no buildlog to analyze. However
the package built fine locally and I can confirm that it fixes the
problem. I won't mark it as verified due to the launchpad build failure
that probably needs investigation. Thanks Colin!

[Kernel-packages] [Bug 1939177] Re: Ubuntu 20.04.2 LTS kernel 5.11.0-25 zfs send | receive broken

2021-08-26 Thread Brian Murray
Hello TimK., or anyone else affected,

Accepted zfs-linux into focal-proposed. The package will build now and
be available at https://launchpad.net/ubuntu/+source/zfs-
linux/0.8.3-1ubuntu12.13 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-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. 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.

  https://github.com/openzfs/zfs/issues/12462

  Ubuntu 20.04.2 LTS
  Kernel: 5.11.0-25-generic #27~20.04.1-Ubuntu
  zfs-0.8.3-1ubuntu12.12
  zfs-kmod-2.0.2-1ubuntu5

  Trying to run zfs send | receive and getting an error:

  # zfs send  'rpool/home'@'autosnap_2020-08-01_00:59:01_monthly' | zfs receive 
 -s -F 'nas/rpool_backup/home'
  cannot receive: failed to read from stream
  cannot receive new filesystem stream: dataset does not exist

  This used to work before the recent Ubuntu kernel update from 5.8 to 5.11
  Kernel 5.8 came with zfs-kmod-0.8.4-1ubuntu11.2

  Ubuntu updates that broke it:

  Upgrade: linux-headers-generic-hwe-20.04:amd64 (5.8.0.63.71~20.04.45, 
5.11.0.25.27~20.04.10), linux-
  image-generic-hwe-20.04:amd64 (5.8.0.63.71~20.04.45, 5.11.0.25.27~20.04.10), 
linux-generic-hwe-20.04
  :amd64 (5.8.0.63.71~20.04.45, 5.11.0.25.27~20.04.10)

  Sending the zfs send part to a file works, but then sending the file
  to zfs receive also fails. The dump file size seems reasonable but the
  contents may not be correct.

  [Test Plan]

  1. create test pool and backup pool

  sudo zpool create pool /dev/vdb1
  sudo zpool create backup  /dev/vdc1

  2. populate pool with some files and create some snapshots

  sudo  zfs snapshot pool@now1

  create some more files etc, make another snapshot

  sudo  zfs snapshot pool@now2

  3. perform send/recv using -s option:

  sudo zfs send pool@now1 | sudo zfs receive -vFs backup
  sudo zfs send -i pool@now1 pool@now2 | sudo zfs receive -vFs backup

  Without the fix, the -s option on the receive fails. With the fix it
  works fine.  Test with focal 5.4 and 5.11 kernel to exercise 0.8.x and
  2.x kernel ZFS drivers.

  [Where problems could occur]

  The main fix nullifies the deprecated  action_handle option so that
  it's not checked, this allows 0.8.x userspace it to be forwardly
  compatible with 2.x kernel ZFS and also since it is deprecated in
  0.8.x it makes not difference to the 0.8.x kernel ZFS driver. Thus the
  risk with patch action_handle is very small.

  Included in the fix is a send/recv upstream bug fix 
4910-Fix-EIO-after-resuming-receive-of-new-dataset-over-a.patch that makes 
send/recv more resilient by making  zfs receive to always unmount and remount

  resumed stream.  The change is upstream for ~10 months and has minimal impact

5.11.0.25.27~20.04.10), linux-

  Sending the zfs send part to a file works, but then sending the file
  to zfs receive also fails. The dump file size seems reasonable but the
  contents may not be correct.

  [Test Plan]

  1. create test pool and backup pool

  sudo zpool create pool /dev/vdb1
  sudo zpool create backup  /dev/vdc1

  2. populate pool with some files and create some snapshots

  sudo  zfs snapshot pool@now1

  create some more files etc, make another snapshot

  sudo  zfs snapshot pool@now2

  3. perform send/recv using -s option:

  sudo zfs send pool@now1 | sudo zfs receive -vFs backup
  sudo zfs send -i pool@now1 pool@now2 | sudo zfs receive -vFs backup

  Without the fix, the -s option on the receive fails. With the fix it
  works fine.  Test with focal 5.4 and 5.11 kernel to exercise 0.8.x and
  2.x kernel ZFS drivers.

  [Where problems could occur]

  The main fix nullifies the deprecated  action_handle option so that
  it's not checked, this allows 0.8.x userspace it to be forwardly
  compatible with 2.x kernel ZFS and also since it is deprecated in
  0.8.x it makes not difference to the 0.8.x kernel ZFS driver. Thus the
  risk with patch action_handle is very small.

  Included in the fix is a send/recv upstream bug fix 4910-Fix-EIO-
  after-resuming-receive-of-new-dataset-over-a.patch that makes
  send/recv more resilient. This change again is a small risk.

[Kernel-packages] [Bug 1939177] Re: Ubuntu 20.04.2 LTS kernel 5.11.0-25 zfs send | receive broken

2021-08-09 Thread Michael Albert
I want to confirm that I'm also facing the same issue and that adding
the --no-resume option does indeed fix the issue for syncoid.

It does seem like the correct solution is to update the ZFS tools in the
HWE stack when the kernel is updated. However, there does not seem to be
a way to do this (short of compiling from source, which I would really
like to avoid). Is there any possibility of moving the LTS HWE stack to
a model where the ZFS tools are updated when the kernel module is
updated?

2021-08-07 Thread TimK.
I asked in the zfs github issue and the answer is that the versions must
match. It might be an incompatibility between zfs-0.8.3-1ubuntu12.12 and
zfs-kmod-2.0.2-1ubuntu5 though not sure how easy it is to deal with this
when using HWE.

I've also seen this. I wondered if the problem is that the libraries and

FWIW I'm using it with sanoid/syncoid

supported by the zfs version.

syncoid has a --no-resume option that might work (but have yet to try).

  # zfs send  'rpool/home'@'autosnap_2020-08-01_00:59:01_monthly' | zfs receive 
 -s -F 'nas/rpool_backup/home'
  cannot receive: failed to read from stream
  cannot receive new filesystem stream: dataset does not exist

  This used to work before the recent Ubuntu kernel update from 5.8 to 5.11
  Kernel 5.8 came with zfs-kmod-0.8.4-1ubuntu11.2

  Ubuntu updates that broke it:

  Upgrade: linux-headers-generic-hwe-20.04:amd64 (5.8.0.63.71~20.04.45, 
5.11.0.25.27~20.04.10), linux-
  image-generic-hwe-20.04:amd64 (5.8.0.63.71~20.04.45, 5.11.0.25.27~20.04.10), 
linux-generic-hwe-20.04
  :amd64 (5.8.0.63.71~20.04.45, 5.11.0.25.27~20.04.10)

  Sending the zfs send part to a file works, but then sending the file
  to zfs receive also fails. The dump file size seems reasonable but the
  contents may not be correct.
