Docker hangs with xfs using aufs storage driver

[Akihiro Suda]

SRU Justification

Impact: Running the yum command in a Centos/RHEL container causes the process to hang enter uninterruptible sleep mode if /var/lib/docker is hosted on an XFS filesystem while the AUFS storage driver is used.

Fix: Commit e34c81ff96415c64ca827ec30e7935454d26c1d3 from upstream aufs-standalone. Requires prerequisite commit b4d3dcc92a13d53952fe6e9a640201ef87475302.

Test Case: Test scenario described above. Kernel with fixes applied has been confirmed by reporter to fix the issue.

Regression Potential: Both patches have been in upstream aufs-standalone for a while now and included in the artful kernel as well as currently being included in the upstream branch for 4.10. Therefore they are well tested and unlikely to cause regressions.

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Ubuntu 16.04 and 17.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
kernel 4.10.0-28-generic

3) What you expected to happen

Docker with AUFS on XFS works.

4) What happened instead

It hangs up

As reported in https://github.com/moby/moby/issues/34361 , AUFS on XFS needs this fix for kernel 4.10: https://github.com/sfjro/aufs4-standalone/commit/e34c81ff96415c64ca827ec30e7935454d26c1d3

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1709749

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Seth Forshee (sforshee)]

I've backported the fix and necessary prerequisite patches and prepared a test build so you can verify that these fix the issue. Can you please test the kernel at the link below and let me know your results?

http://people.canonical.com/~sforshee/lp1709749/

Let me know if you have questions about which packages you need to install, likely only linux-image-*-generic and linux-image-extra-*-generic but possibly others if you use dkms drivers or something like that. Thanks!

[Seth Forshee (sforshee)]

Oh and you can ignore the request for logs in comment #1.

[Akihiro Suda (suda-kyoto)]

Yes, I confirmed that the lp1709749 kernel works as expected.
Thank you for the work.

This appears to be a duplicate of https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1679768 and also affects Xenial when using hwe backported kernel.

[Kleber Sacilotto de Souza (kleber-souza)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-zesty' to 'verification-done-zesty'. If the problem still exists, change the tag 'verification-needed-zesty' to 'verification-failed-zesty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Kleber Sacilotto de Souza (kleber-souza)]

Hello Akihiro,

Could you please verify the fix with the latest Zesty kernel in -proposed?

Thank you!

[Akihiro Suda (suda-kyoto)]

Confirmed 4.10.0-34-generic (x86_64) works, sorry for late reply

[Kleber Sacilotto de Souza (kleber-souza)]

Hello Akihiro,

Thank you verifying the fix.
