Hi @mathieu-tl,

Given the explanation in the previous comment, can't this be considered
a way to fix a bug - rather than a feature?

Thank you

(In reply to comment #6)

Interestingly I forgot the point in time we are currently.

Yes, indeed, it's just a convenient way of adding WWIDs, however, its
importance lies if Ubuntu wants to enable its users to install
multipath-tools-boot (say, in a LVM/multipath scenario) to boot from
multipath.

If the root fs is locked due to a LVM volume, it cannot be multipathed, thus 
its WWID won't be added to the list.
During boot, the only chance for the LVM volume to be mounted from the 
multipath device is if the WWID is present (so the udev rule which removes the 
partition block devices from individual paths can succeed).

So it's now a chicken and egg problem. You need to boot from multipath
in order to be able to multipath the device with the root fs LVM LV. :-)

With multipath -a, you can just install multipath-tools-boot, multipath -a 
/dev/sdX, update-initramfs -u; done.
Without it, well, you can replace multipath -a for some multipath -v3 /dev/sdX 
| grep 'uid =' | sed/awk >> /etc/multipath/wwids.. but you see, it doesn't look 
quite 'this is how it should be done'.

Ryan,
congrats, well done. :-) I did an extended test with this multipathd/kpartx on 
a z/VM guest and in LPAR overnight and it ran very well. Even after 300 
"off/on" cycles all paths were "active ready running" at the end.
So, please go ahead with this. I will continue testing this when it is in 
xenial/main, since some of my other tests rely on this.

I will close this defect when this fix is in xenial/main.

The s390 backport looks good for libseccomp 2.2.3-3. However this upstream 
patch is missing:

commit d2ca11b7cdddbba3782b1e306ceacf19e898faee
Author: Heiko Carstens 
Date:   Mon Nov 9 13:15:39 2015 +0100

arch: update s390/s390x system call tables
s390 and s390x gained quite a few new system calls:
- numa related system calls
- the separated socket system calls
- two more s390 specific pci mmio system calls
All architectures got the new membarrier and userfaultfd system calls.

This patch updates the s390 specific system call tables and updates other
architectures where needed.

Also remove some extra whitespace from the s390 specific system call
tables.

Both 'make check' and './regression -T live' still work for s390 and s390x
after this update.

[Bug 1540401] Boot log with excerpts of systemd-udevd --debug

[bugproxy]

--- Comment on attachment From mauri...@br.ibm.com 2016-02-03 19:01

Adding an attachment (xz) of the boot log with systemd-udevd --debug running,
in order to verify the udev processing of the rules.

You may notice multipath -c is called several times only for
SUBSYSTEM==BLOCK devices, and partx -d is called only for the devices
part of a multpath device (ie, multipath -c has exit code 0).

Thank you Mauricio !!

I verified the same on PowerVM Lpar scenario, issue is fixed with
packages in -proposed :

root@miglp2:~# dpkg -l|grep multipath
ii  multipath-tools0.4.9-3ubuntu7.10ppc64el 
 maintain multipath block device access
ii  multipath-tools-boot   0.4.9-3ubuntu7.10all 
 Support booting from multipath devices

Lpar boots up with /boot :
---
root@miglp2:~# df |grep boot
/dev/mapper/mpath3-part2241965   60518168955  27% /boot

Thanks,
Manju

Results show, that this combination does not harm, instead it solves the
subject problem, even after 100 cycles.

Ryan, but it's up to you what you are going to integrate to fix this
bug.

--- Comment From thorsten.di...@de.ibm.com 2016-02-29 08:50 EDT---
Regarding the above strange behaviour in #5:
On a 4.4.0-8 system freshly installed (not updated from 4.4.0-7) with 
libzfcphbaapi0 installed the paths are recoverd and re-added as expected, as 
already described in case #2. And again, with case #1 the problem is 
reproducable.

What is this libzfcphbaapi0 package doing undercover? Normally it has no
interatice with multipath daemon. Does it change anything in the
multipath configuration?

Adding the libzfcphbaapi0 package to prevent symptoms of this bug can
not be the solution and it might be just by chance, that the symptom
vanished. I talked to zfcp development, and they confirmed that.

As already promised, I will continue some long term tests (cable pull
and other path loosing scenarios) on a 4.4.0-8 system with multipath-
tools_0.5.0+git1.656f8865-4 and kpartx_0.5.0+git1.656f8865-4. Results
should be available by tomorrow.

Hi Ryan,

I followed your proposal, installed 
multipath-tools_0.5.0+git1.656f8865-4_s390x.deb as described, and it worked 
fine and as expected, i.e. described problem does not occur.
On another system I installed both 
multipath-tools_0.5.0+git1.656f8865-4_s390x.deb and 
kpartx_0.5.0+git1.656f8865-4_s390x.deb - with the same result.
I did a detach/attach of the zfcp device and found, that it apperas for some 
seconds in status active faulty running, then it changed to failed faulty 
running and remained in that state until reattachment of the device. Then it 
changed back to active ready running.

Hi Christian,

in addition I did the following tests:

1. On a freshly installed xenial (installer version 427, kernel 4.4.0-8) with 
the already mentioned multipath.conf I found, that no zfcphbaapi stuff is 
installed per default.
kernel 4.4.0-8
multipath-tools 0.5.0-7ubuntu15 (was 7ubuntu14 before) and kpartx 
0.5.0-7ubuntu15
I did a detach/attach of the zfcp device and found, that it apperas for some 
seconds in status active faulty offline, then it changed to failed faulty 
offline and vanished and did not reappear upon reattachment of the device. I 
had the zfcp LUNs configure manually (via sysfs)

2. Then I installed zfcp-hbaapi-utils_2.1.1-0ubuntu1_s390x.deb and
libzfcphbaapi0_2.1.1-0ubuntu1_s390x.deb on top. With these two
additional packages I could not reproduce this problem.

3. I installed a system with kernel 4.4.0-7 and multipath-tools
0.5.0-7ubuntu14 + the above mentioned zfcphbaapi stuff. Problem was
reproducable.

4. I updated that system to multipath-tools 0.5.0-7ubuntu15. Problem was
still reproducable.

5. I updated that system to kernel 4.4.0-8. It should be now similar to
case #2. But problem was still reproducable. strange.

6. I switched several times back and forth between multipath-tools
0.5.0-7ubuntu15 and multipath-tools_0.5.0+git1.656f8865-4_s390x.deb.
With git1 it worked always, with 7ubuntu15 never. (although it did on a
freshly installed system, see #2)

So, for now we have two ways to solve/circumvent this problem:
a) use an updated multipath-tools package (from debian sid)
b) use an updated multipath-tools/kpartx packages from ubuntu (>= version 
0.5.0-7ubuntu15) AND zfcp-hbaapi-utils_2.1.1-0ubuntu1_s390x.deb and 
libzfcphbaapi0_2.1.1-0ubuntu1_s390x.deb on top. But that didn't help always 
(see case #5 above)

I found different values for path_selector in multipath-tools versions of 
ubuntu and debian:
ubuntu15: round-robin 0
debian-git: service-time 0
Then I set this in multipath.conf to the (usual) default "round-robin 0"
And with debian-git version the problem was still solved. So this setting 
should not matter.

Ryan,
although obviously only fixes from multipath-tools_0.5.0+git1.656f8865-4 are 
required to fix this problem, please consider and analyze, if it is better to 
get the complete set of patches in both multipath-tools AND kpartx from debian 
upstream (sid) instead of cherry picking some fixes.
The debian sid combination of multipath-tools AND kpartx does obviously not 
harm and is already 6 weeks old.

Anyway, I will do some other test with this combination.

Ok. Thanks for the update.

If that helps, I've been testing that more manually, either installing
the packages at the end of the installation (cd /target/tmp && wget
<...>.deb && chroot /target dpkg -i /target/tmp/*.deb), or by installing
the packages after system is already installed (just manually fixing the
boot problem at initramfs time break=pre-multipath for example).

Regards.

--- Comment From mauri...@br.ibm.com 2016-02-25 12:21 EDT---
Correction:

-packages at the end of the installation (cd /target/tmp && wget <...>.deb &&
-chroot /target dpkg -i /target/tmp/*.deb),

+packages at the end of the installation (cd /target/tmp && wget <...>.deb &&
+chroot /target dpkg -i /tmp/*.deb),

BTW, if you have a chance, it'd be nice to have a Trusty 'affects' row
for tracking purposes. Otherwise it seems this is already resolved
(despite your comment).  Thanks.

Hi Ryan,

on the most recent repro I already had version: 0.5.0-7ubuntu14 - same symptom.
With
# echo "offline" > /sys/class/block/sdb/device/state
I could not reproduce this symptom on z Systems.

Approved repro is as follows:
z Systems LPAR: chchp -c 0 ;sleep 30;chchp -c 1 
z Systems z/VM guest: vmcp det ;sleep 30;vmcp att  "*"

Cool, thanks; glad to see the patch made Xenial.

This is still on the queue for Trusty, correct?
- there's no 'Affects' line for Trusty on the LP bug header yet.

[Bug 1540401] [PATCH V2] booting with LVM on multipath devices

[bugproxy]

--- Comment on attachment From mauri...@br.ibm.com 2016-02-04 10:20 
EDT---


Hi Canonical,

Please consider this patch V2 for review.

It includes 2 important changes:
- The '--nr 1-1024' to the partx command.
- Built on top of the patches for multipathd/initramfs (LP #1526984) and kpartx 
w/ spaces (LP #1432062) -- both required.

Thanks,

Hi @mathieu-tl

(In reply to comment #44)
> 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*

I could reproduce the problem in that scenario by using break=multipath in the 
kernel cmdline
(which forces LVM udev rules to run before multipath discovery).

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

I'd expect it to fail in any case with LVM on top of multipath devices,
and LVM scan/volume activation happening before multipath discory
(root cause: LVM locking an individual path before multipath takes it).

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

Sure.

Is multipath-tools - 0.5.0-7ubuntu10 going to be available in the repository 
anytime soon? We want to verify the problem is fixed before completing our 
testing for 14.04.4, which we will be done with early next week...

That version is for 16.04 - it is already fix released/available in the
repository.

The version for 14.04.4 (something like  0.4.9-3ubuntu7.) is
not yet fix released/available.

There's no defined date for when it will be made available - but it is
in the list of multipath fixes that Canonical's team is aware of and
working on. Perhaps there will be single update w/ more than 1 bug
fixed.

There's likely a number of tasks on their side as well, and this one is
prioritized as Critical, so things should happen as best as possible.

Hello,

The openvswitch package previously existed in Trusty so is the problem
reported something new to version 2.4.0?

The test described in the bug fails in Ubuntu 14.04.2.

The following packages were tried as well: libnuma1 2.0.9~rc5-1ubuntu3
and numactl  2.0.9~rc5-1ubuntu3

In all cases the test failed. The efix for 14.04.1 provided by Thierry
Fauck worked but it was not used  in 14.04.02

[Bug 1526984] Support multipathd in the initramfs for async device discovery

[bugproxy]

--- Comment on attachment From mauri...@br.ibm.com 2016-01-11 07:58 
EDT---


Hi Canonical @mathieu-tl,

This patch implements multipathd in the initramfs, and is reported to resolve 
the problem
(tested by developer and test team for more than 10 reboots each).

It's on top of the patch in LP 1432062 comment 10 (requirement, since
multipathd -B might create devmaps w/ spaces in names).

Is it still in the window for 14.04.4?  
Thanks!

The test described in the bug fails in Ubuntu 14.04.2.

The following packages were tried as well: libnuma1 2.0.9~rc5-1ubuntu3
and numactl  2.0.9~rc5-1ubuntu3

In all cases the test failed. The efix for 14.04.1 provided by Thierry
Fauck worked but it was not used  in 14.04.02

The test described in the bug fails in Ubuntu 14.04.2.

The following packages were tried as well: libnuma1 2.0.9~rc5-1ubuntu3
and numactl  2.0.9~rc5-1ubuntu3

In all cases the test failed. The efix for 14.04.1 provided by Thierry
Fauck worked but it was not used  in 14.04.02

Subject: [PATCH] libnuma.so On ppc64el, cpu number are not contigous

Commit 32075635db57c3d5efe12f8fb569af857e01ccad issuea warning message
/sys not mounted when it find a non existent cpu number, and that's the
default for multinode on ppc64el bare metal installed system. This patch
removes the message when the /sys entry doesn't exist, but use the return
code.
