The merge is completed; it has been uploaded to the xenial review queue;
we should get it in the archive proper soon (needs to be accepted by the

[Bug 1555345] Re: ISST-LTE: pVM:multipath -ll cannot show mpath device

[Mathieu Trudel-Lapierre]

The milestone for this is indeed still 16.04; but we might use a
different way to get the fix than applying the patch. We have Ryan here
working on merging multipath-tools (a git snapshot that should contain
the fix and many others) from Debian; once that is completed and lands
in the release we'll revisit this bug, make sure whether it is fixed or
if it still needs to have the patch applied on top.

Or, if we end up in the case that we can't land the larger update, we'll
land just this patch. In any case, this means we'll delay fixing this
here bug for now until the situation with the merge is completed -- that
is tracked in bug 1551952.

I've triaged this bug, but it's quite very late in the cycle to ship new
features, especially one such as this one which appears to be mostly
just a convenient way of adding WWIDs to the multipath list.

(which probably don't even need to be overriden), but this isn't a

[Bug 1551828] Re: kpartx causes kernel oops when NVMe devices is not in blacklist

[Mathieu Trudel-Lapierre]

** Description changed:

+ [Impact]
+ Users expecting to use multipath over NVMe device will notice hangs with any 
software attempting to use the device-mapper devices (/dev/dm-* or 
/dev/mapper/mpath*).
+ 
+ [Test case]
+ 1) Setup multipath over nvme. (should not be possible with the patch in)
+ 2) Run kpartx -av /dev/dm-device-mulipath-over-nvme   (will hang without the 
patch)
+ 
+ [Regression Potential]
+ Minimal. This removes a theoretically valid use case of multipath devices 
using NVMe disks, which is not technically supported and leads to software 
hangs (and thus installs will not complete, and setting up multipath over NVMe 
post-install would hang).
+ This only affects nvme devices; so any storage device using the "nvme" naming 
would no longer be able to setup multipath even if technical specifications 
were to change sufficiently to support multipath over NVMe (or if some other 
device starts using this naming which isn't affected by the same limitations).
+ 
+ 
+ -
+ 
  When on bare metal uses NVMe devices - kpartx cause kernel oops.
  http://paste.openstack.org/show/488638/
  
  Also any tools which works with disks (e.g. fdisk, lsblk) hangs in D state 
(uninterruptible sleep) while trying to to read /dev/dm-X.
  This bug is already described and fixed in upstream 
(http://git.opensvc.com/gitweb.cgi?p=multipath-tools/.git;a=commitdiff;h=5c412e47e589b5325ed7de6cba86d906a671d9df)
  
  I made patches for trusty and xenial versions of multipath-tools.
  Patches which fix issue is in attach.
  Could you apply this patches please, at least for trusty version?

preparing.

[Mathieu Trudel-Lapierre]

It's on my list, yes.

The idea however is that I haven't uploaded it because it is so annoying
to test these patches from a PPA, I uploaded the changes for xenial to
the archive for further testing since it looked like it worked
sufficiently to not break too many use cases.

Verified; this works as expected:

kpartx -av adds a loop device node and mounts the image, and sets up the 
partitions.
kpartx -dv deletes the partition maps and removed the loop device node.

[Bug 1538775] Re: multipath-tools-boot relies on scsi_wait_scan module, fails multipath setup

[Mathieu Trudel-Lapierre]

FWIW, it's not so much as a flat no for fixing this with a sleep as that
any possible value for sleep (unless it's unreasonably high) will still
fail for some people... and high values are just inconvenient since they
slow the boot down. It's generally just not a very useful general fix,
even if it works locally as a workaround.

Stuart, did you file a new bug for the actual scan wait process for
devices?

[Bug 1543430] Re: kpartx 0.5.0-7ubuntu11 fails to remove loop mapping on kpartx -d

[Mathieu Trudel-Lapierre]

Ugh, yeah, I see now that the patch fixing dealing with loopbacks at all
"regresses" in a way, but not dealing correctly with the loop entries
even though it appears to deal with the devmapper table just fine.

I'm looking at it right now, it's not pretty. There are basically two
ways I can think of to deal with this. Either relying more on
loopdev/device than S_ISREG on the buf that describes the file opened
(we needed to stat the loopback device after picking it, otherwise no
major/minor numbers to do the partition mappings), or hacking
buf.st_mode to convince kpartx we're still dealing with a regular file.

I'm trying to see what might break if we just use loopdev or device
everywhere. I will upload as soon as I'm reasonably confident this does
not further break things, and I'll adjust the autopkgtest accordingly.

[Bug 1526984] Re: ISST-LTE: root mpath device unavailable after installation

[Mathieu Trudel-Lapierre]

Hum, that's kind of weird. You should see disks being picked up by
multipath if they should, even if they are detected *after* multipath
scripts run (because multipathd...). They wouldn't be detected before
multipath runs, because then they would most likely be remapped anyway
(unless something else claims them).

Could you file a new bug for this, including the output of multipath -v4
taken from the initramfs? You may stop the boot process by adding "break
=pre-multipath" to break boot just before the multipath scripts. At that
point, you'll need to modprobe dm_multipath;  and then you should be
able to run multipath -v4. If you exit from there boot should complete
(hopefully succesfully, since there will have been some extra delay).

[Bug 1526984] Re: ISST-LTE: root mpath device unavailable after installation

[Mathieu Trudel-Lapierre]

Well, to be honest there isn't anything we can do in multipath-tools or
udev if the scans aren't generating events. The best option then is to
look at the driver, if it permits some control of how the scans happen,
and if not, why.

[Bug 1538775] Re: multipath-tools-boot relies on scsi_wait_scan module, fails multipath setup

[Mathieu Trudel-Lapierre]

Stuart,

I'm aware of that, but there are two different issues at play here: the
detection and scanning of drives, and the fact that scsi_wait_scan is
still in the script. The upload should likely fix both; but I'm closing
this bug here because it's about scsi_wait_scan. The other bugs are
referenced in the uploaded package, linked in the previous comment.

[Bug 1540401] Re: ISST-LTE: Ubuntu14.04.4 lpar fails to boot after installation: "The disk drive for /boot is not ready yet or not present"

[Mathieu Trudel-Lapierre]

This isn't obvious to reproduce. So far, I haven't had the system fail
to boot or fail to mount all partitions. I have been testing *without*
multipath-tools 0.4.9-3ubuntu7.8; so not using multipathd in the
initramfs.

I suppose it may be that I'm using a partitioning that happens to work?

Could you please add the output of: sudo dmsetup ls --tree -o blkdevname

No failure after 20 reboots:

mpath0-part1  (252:2)
 └─mpath0  (252:0)

My test system is indeed a ppc64el qemu VM using spapr-vscsi.

Will setup a new system using snapshot to test with multipath-tools
0.4.9-3ubuntu7.8.

I'd like to re-validate this for myself before we mark it verification-

openssh with audit support for this to work, so let's take another look.

Marking back to verification-needed.

[Bug 1486370] Re: ISST-LTE: not all mpath device files are symbol link

[Mathieu Trudel-Lapierre]

** Description changed:

  [Impact]
  Minimal impact, this is limited to aesthetic issues; devices should if 
possible all be actual block device nodes rather than symlinks.
  
  [Test case]
  1) ls -l /dev/mapper
  2) Reboot, try again.
+ 
+ Also:
+ while true; do kpartx -d -p -part /dev/dm-2;udevadm settle; kpartx -a -p 
-part /dev/dm-2; udevadm settle;done
+ 
+ Or:
+ while true; do multipath -F; multipath; done
+ 
  
  [Regression potential]
  Timing issues may cause delays in generating device nodes or symlinks due to 
the need for multipath-tools, device-mapper and udev to synchronize.

  Either symlinks to the dm devices or block devices which refer to them

  BTW, that expectation is per the SRU policy.
  
  And the problem cause is likely a race involving udev rules (multipath &
  kpartx), and possibly multipathd.

  Release: Ubuntu 14.04.3 LTS
  Kernel: linux-image-3.16.0-59-generic
  A clean system installed fresh today (2016-01-27)
  
  In attempting to configure a system to boot-from-SAN and enable
  multipath support I ran into an issue whereby despite the multiple paths
  being detected (when running the multipath command from the CLI) the
  configuration wasn't being enabled at boot. After examining /usr/share
  /initramfs-tools/scripts/local-top/multipath I found the following:
  
  verbose && log_begin_msg "Waiting for scsi storage"
  { rmmod scsi_wait_scan ; modprobe scsi_wait_scan ; rmmod scsi_wait_scan ; } 
>/dev/null 2>&1
  verbose && log_end_msg
  
  The problem appears to be that the scsi_wait_scan module doesn't  exist
  and so there is no wait before the multipath scan is performed. I
  managed to observe this briefly during bootup (with the script edited)
  and could see it performed the scan before sda/sdb was discovered.
  
  I also found a debian bug report indicating the module was removed a
  while back (https://lists.debian.org/debian-
  kernel/2012/05/msg00791.html).
  
  After adding in an artificial delay for testing the multipath command
  does what is expected and configures the paths accordingly. I'm not sure
  what the correct approach is if the scsi_wait_scan module is removed.
  
  I also found that the same local-top script doesnt have the dm-round-
  robin module loaded (but it is included in the initrd by the associated
  hook script), however I'm not sure if that is by design. I know I need
  it for my specific use-case, but don't know if it is deliberately
  excluded to prevent breakage on SAN units that don't support native
  round-robin.

[Bug 1432062] Re: multipath-tools-boot: support booting without user_friendly_names on devices with spaces in identifiers

[Mathieu Trudel-Lapierre]

** Description changed:

+ [Impact]
  If a system is not installed w/ multipath support (i.e., no 
disk-detect/multipath/enable=true), the /etc/multipath.conf file is not 
installed.
  If an user later installs multipath-tools-boot, it will enable the udev rules 
for multipath support.
  Those rules don't handle disk devices w/ spaces on their names/uuids/models 
very well..
  
  That's because of udev's SYMLINK command using spaces to separate
  multiple links, and the kernel sysfs/dm informing \x20 instead, which is
  not correctly interpreted by some commands, resulting in file not found
  errors, for example.
  
  Thus, the system fails to boot.
+ 
+ [Test case]
+ Requires installing on a system where there are spaces in the name of the 
device make/model data; for instance, on POWER8 with IPR disks, or with QEMU.
+ 1) Install system with multipath support 
('disk-detect/multipath/enable=true').
+ 2) Boot the system.
+ 3) Edit /etc/multipath.conf, remove "user_friendly_names yes" ; replace with 
"user_friendly_names no", or remove /etc/multipath.conf.
+ 4) Update the initramfs: sudo update-initramfs -u
+ 5) Reboot.
+ 
+ [Regression potential]
+ Minimal. Systems with names in the disk make/model data would not boot 
without user_friendly_names enabled. This patch will allow multipath-tools to 
correctly handle these devices in the case where friendly names are not enabled 
by using the devices major/minor numbers rather that its path.
+ 
+ 
  
  There's no problem, however, if user_friendly_names is enabled in
  multipath.conf (which is enabled in the default multipath.conf from the
  installer, if it has multipath enabled).
  
  Notice it's an acceptable case to install w/out multipath support, and
  enable it later for booting.
  
  Disk devices w/ spaces in naming is not common over SAN/storage systems, but 
that happens often for conventional disks; for example:
  - IBM IPR  ( IBM IPR-0   5DB6F480 )
  - IBM VDASD ( AIX VDASD   00c96f074c00014bb8e713f0.14 )
  - QEMU HARDDISK ( QEMU QEMU HARDDISK  )
  
  So, please, is it possible to ship the default multipath.conf (e.g.,
  from installer) w/ multipath-tools-boot?
  
  For users not to their systems failing to boot after installing
  multipath-tools-boot manually, after a non-multipath install.

[Bug 1526984] Re: ISST-LTE: root mpath device unavailable after installation

[Mathieu Trudel-Lapierre]

** Description changed:

+ [Impact]
+ This affects users of multipath systems where devices may be slow to be 
detected. (See below).
+ 
+ On some systems disks may be slow to be detected due to a number of
+ reasons: slow disks, spin delay, large number of devices to scan, etc.
+ If the disk containing the root filesystem fails to be detected/scanned
+ when the multipath initramfs scripts are run, the system will give up
+ and fail to load the rootfs, which results in a failure to boot (and the
+ user will be thrown into a busybox shell in the initramfs).
+ 
+ [Test case]
+ Boot the system.
+ 
+ [Regression Potential]
+ Given that this changes the load order for the system, it may cause some 
delay in booting due to the extra time taken to load all maps for the rootfs to 
become available through multipath. Also, crashes in multipathd may now affect 
early boot.
+ 
+ ---
+ 
  Canonical FYI:
  
  We appear to have a regression in the current 14.04 environment back to
  the behavior originally outlined in Comment #10 of LP Bug 1429327.
  
  ---Problem---
  
  A multipath install of 14.04.04 fails to create the install mpath
  device on subsequent boots.  While the root filesystem ends up being
  mounted on top of one of the path devices, other partitions on that
  multipath device will not be automatically found.
  
  ---Additional details---
  
  For one example host, the install disk was set up with a root and
  swap partition:
  
  Dec 14 21:37:55 disk-detect: create: mpath0 (35000c5007655a10f) undef IBM

  The resulting fstab entries after install were:
  
  /dev/mapper/mpath0-part2 /   ext4errors=remount-ro 0 1
  /dev/mapper/mpath0-part3 noneswapsw0 0
  
  In post-install boots, the multipath command appears to be executed
  prior to any disks being discovered:

[Bug 1473903] Re: parted will generate two devices when adding one partition on mpath device

[Mathieu Trudel-Lapierre]

I managed to find a patch I'm testing now, which adds udev sync support
to parted 2.3 (in 14.04) which is already in parted 3.2.

Testing is in progress, this should help remove the "device is busy"
warnings.

As for the two devices, other patches to multipath-tools and parted's
partitioning policy should fix this.

[Bug 1486370] Re: ISST-LTE: not all mpath device files are symbol link

[Mathieu Trudel-Lapierre]

Could you please verify that you're not seeing this issue on 16.04? It
looks like the patch found should solve this, but it's hard to verify
given that this is very dependent on the speed of the system on which
multipath-tools run, as well as how fast udev can run, scan devices,
etc.

** Description changed:

+ [Impact]
+ Minimal impact, this is limited to aesthetic issues; devices should if 
possible all be actual block device nodes rather than symlinks.
+ 
+ [Test case]
+ 1) ls -l /dev/mapper
+ 2) Reboot, try again.
+ 
+ [Regression potential]
+ Timing issues may cause delays in generating device nodes or symlinks due to 
the need for multipath-tools, device-mapper and udev to synchronize.

  This shouldn't be a problem at all.
  Either symlinks to the dm devices or block devices which refer to them 
directly (via major:minor number) will work.
  
  It isn't ideal, though.

[Bug 1478087] Re: Add libaudit support

[Mathieu Trudel-Lapierre]

** Description changed:

+ [Impact]
+ Auditing support is a commonly used feature in large enterprises, and allows 
better tracking of actions happening on secured systems, especially when it 
comes to accounting for login events.
+ 
+ Such systems fail to correctly list login events in aureport due to some
+ software not integrating libaudit.
+ 
+ [Test Case]
+ 1) Install auditd
+ 2) Login to the system multiple times (or allow for others to connect to the 
system)
+ 3) Run aureport -l
+ 
+ System should list login information.
+ 
+ [Regression Potential]
+ There is minimal risk for issues since libaudit support only allows for 
generating extra logging saved on the local system. A possible side-effect of 
this may be that systems on which auditing is enabled and where there are many 
users of the affected software (see bug tasks), such as many logins over SSH, 
there may be an increased demand on disk space necessary for the auditing data.

  This looks like a bug in aureport or libaudit. In addition to giving
  admins falsely empty record selections, this would prevent successful
  completion of a Common Criteria certification.

Did you modify the path selector yourself?

path_selector   "service-time 0"

This requires loading the dm-service-time module.

[Bug 1535898] Re: Trusty & Vivid multipath-tools (multipathd) seg-fault core dump

[Mathieu Trudel-Lapierre]

And now that I did some more testing with Louis on this, we were able to
"run into" a crash with mpp->alias attempted to be freed but failing,
which isn't quite the same backtrace as I had pasted earlier. It does
look like it might be similar to the issue reported by valgrind (depends
largely on the presence of the debug symbols).

Pending further testing, but I've prepared the attached debdiff, which
should address the state of mpp->alias.

The crash you're hitting is something very different than what valgrind
is finding (though I agree technically valgrind is correct in pointing
this out, and it looks as though some of it is addressed upstream).

That kind of makes me suspicious of the state of the kernel multipath
modules. Which ones are loaded of the dm-* modules? Does anything show
up in /var/log/syslog? It would be quite helpful if you could attach
syslog to this bug report.

[Bug 1469143] Re: kpartx -d fails with image paths longer than 63 characters

** Description changed:

+ [Impact]
+ Users of kpartx to load disk images, possibly multiple images with the same 
file name (but in different paths).
+ 
+ [Test case]
+ See below, also see 
https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1469143/comments/3
+ 
+ [Regression potential]
+ This changes makes the matching for loaded images more robust, and so has a 
very limited risk of regression. Since there is a call to stat() introduced, 
one may notice a slowdown if the stat() call blocks for a reason, and the 
operation will fail if the stat() call fails for any reason, since the device 
and inode are now required.

  $ sudo kpartx -dv 
asfd1asdf2asdf3asdf4asdf5asdf6asfd7asdf8asdf9asf10asdf11asdf12asdf13/disk.img
  
  strace shows that the parameter on the dismount appears to get cut at 63 
chars:
  ioctl(3, DM_LIST_VERSIONS, 0x15b89b0)   = 0

  if the path is 63 chars or less, the dismount also succeeds.
  
  This is quickly becomes an issue if you want to use full disk paths in
  your shell scripts.

[Bug 1509896] Re: IPMI USB SCSI endpoint discovery can fail on OpenPower machines

[Mathieu Trudel-Lapierre]

** Description changed:

- The current ipmitool code can fail to find an IPMI device on my
- OpenPower machine, due to bug in the USB SCSI device discovery process.
+ [Impact]
+ The current ipmitool code can fail to find an IPMI device on my OpenPower 
machine, due to bug in the USB SCSI device discovery process.
  
  This will only happen if the user has adjusted the number of virtual USB
  devices that the BMC exports. However, the failure mode isn't obvious,
  and it prevents the user from using the 'USB' IPMI channel, which is
  required for firmware upgrades.
  
  This is fixed in upstream commit 607cfe6f4, can we backport this to the
  Ubuntu ipmitool for versions at 1.8.15 or earlier?
+ 
+ [Test case]
+ 1- Increase number of virtual USB devices exported by BMC
+ 2- Run ipmitool -I usb lan print
+ 
+ [Regression Potential]
+ Low potential for regression. This increases the number of devices allowed 
for SCSI; since following spec there may be up to 16 devices on a bus. This 
might cause issues still for out of spec systems with more devices on the bus, 
or buggy BIOS incorrectly cleaning up memory for devices that are not present 
(ie. non-zeroed memory that could make ipmi think there is a device when there 
is not).

Is this change really needed on 15.10? It seems to me like we're already
carrying the proper options for 2810XIV given that the only elements
missing from the hw table are setting configuration options to their
default values anyway?

[Bug 1386637] Re: multipath shows non-mpath disks as being multipath

[Mathieu Trudel-Lapierre]

Mauricio,

Have you managed to test this successfully? I was able to build a vm and
test this, but I'm not certain whether the behavior, although it looks
correct in detecting the path changes, it indeed correct.

There's one noticeable difference at least on qemu; when the paths are
detected as removed they stop being listed at all in multipath -ll
output.

[Bug 1503305] Re: iLab: power kvm client after svc node reboot error inject test, multipath output show missing path and missing storage name

[Mathieu Trudel-Lapierre]

I'm ready to apply the patch, but doing this on 14.04 right now would
likely mean further delays for another stable update in progress. I'd
rather wait until that update is done and fully verified (waiting for a
confirmation from mauricfo) before adding a new patch to go through the
SRU process.

I can however apply this now to the devel release and to 15.04 and
15.10.

[Bug 1503305] Re: iLab: power kvm client after svc node reboot error inject test, multipath output show missing path and missing storage name

[Mathieu Trudel-Lapierre]

** Description changed:

+ [Impact]
+ Users of multipath will see incomplete output for the vendor and model values 
for devices where the first path is the path that is failed.
+ 
+ [Test Cases]
+ 1) Experience a failed path:
+ echo 1 > /sys/devices//delete
+ (the above is an example for forcibly removing a path for SCSI via the /sys 
filesystem)
+ 2) run:  sudo multipath -ll
+ 3) Verify the output, see below.
+ 
+ Storage name (vendor and model usually) should always be displayed after
+ dm-* on the header line for a multipath device.
+ 
+ [Regression Potential]
+ This is limited to output and is thus purely a cosmetic fix. Possible issues 
leading from that fix would include crashes due to an incorrect patch or the 
output for vendor/model info for the device to still be incorrect.

[Bug 1496210] Re: multipath-tools lacks the default settings for IBM 2810XIV storage system

[Mathieu Trudel-Lapierre]

This is a trivial change which is a prime target for a SRU, or if
there's another upload of multipath-tools prior to release.

[Bug 1386637] Re: multipath shows non-mpath disks as being multipath

[Mathieu Trudel-Lapierre]

Any news on verifying this?

Edward, looks like the devices aren't set up to have the same serial
number, so I'm not sure why they would ever be picked up by multipath as
being multipath devices. In any case, have you tested the update in
-proposed, which should fix this?

[Bug 1473903] Re: parted will generate two devices when adding one partition on mpath device

[Mathieu Trudel-Lapierre]

Don't both device names actually work fine though? I couldn't find any
blocking issue to leaving both in place, since they don't seem to
interfere with any operation of the system. This would certainly
constitute the least-intrusive change, on account that there would be no
change required.

Otherwise, there doesn't seem to be a straightforward way to fix this.
We basically have two not great options to contend with (unless someone
else can think of another):

1) Patch parted to write -part partitions instead of -p.
This is fine for the installed system, but means we'd need to revert SRUs 
already done for multipath-tools in the installer -- where we expect to see -p 
partitions always, and rewrite them to -part at the end (since there will be 
just kpartx on the installed system), modify partman-multipath to pick up all 
partitions and make them -part. There remains the issue of rewriting fstab 
later on, when comes the time to migrate to multipath 0.5.0 (which changes the 
partition names in other ways too, so unavoidable).

2) Fix kpartx rules either by disabling them or making them use -p only.
This would fix the installed system (since parted creates p partitions itself) 
and detected partitions on drives at boot would show up correctly, but we'd 
need to do other SRU changes to installer bits to not rewrite /etc/fstab to use 
-part as a partition separator. This is apparently a simpler change, but means 
we also need to deal with changing fstab on upgrade for those who use -part, 
which makes it dangerous and very intrusive.

I'd love to get some guidance on this, but I'm thinking not changing
anything for now is the best option; although if there is any effect in
having both devices show up and we need to stop it, then 1) would be
best.

[Bug 1492262] [NEW] maas-enlist-udeb fails enlistment because of missing curl

[Mathieu Trudel-Lapierre]

Public bug reported:

Looks like maas-enlist-udeb (the maas-enlist function for d-i, which
gets run when one selects the ubuntu-server ISO menu option "Multiple
server install using MAAS", has been failing at least since Trusty.

Attached are screenshots and logs for attempting a provisioning via
MAAS, but the enlist step fails: curl is not found, even though the
curl-udeb package is installed.

The system would normally silently fail to enlist and logs be somewhat
hard to get since maas-enlist-udeb.postinst forces a shutdown at its
end, regardless of the result of running /usr/bin/maas-enlist. The
postinst file was modified to remove the shutdown in order to get the
logs.
