Comments

[Andreas Dilger]

This is mostly failing on ubuntu2204, but there was also a failure on RHEL9.0 so it looks like it is a "new kernel" issue related to sendfile.

[Peter Jones]

Could we add this test to always_accept while we're working on a fix and then enforce testing on ubuntu 22.04 immediately to stop any other regressions creeping in?

[Andreas Dilger]

Yes, that is definitely a way forward, and will at least avoid new regressions. We just need to remember to actually fix the problem and remove the subtest from ALWAYS_EXCEPT, as we normally do with similar issues...

I think the check needs to be for the kernel version, and not the distro, since the same issue was also hit on el9.

[Andreas Dilger]

It looks like patch https://review.whamcloud.com/48928 "LU-16258 llite: Explicitly support .splice_write" has fixed this problem for Ubuntu22.04, since that patch and the one based on top if it have both passed:

https://testing.whamcloud.com/sub_tests/46663bdd-3ad0-4af3-8147-5057ac38898a
https://testing.whamcloud.com/sub_tests/5cda616c-c670-4721-9eb4-0b03b733aa94

No other Ubuntu22.04 test runs have passed in the past 4 weeks.

[Andreas Dilger]

Fixed by LU-16258.
