Comments

[Shaun Tancheff]

This is resolved now, these tests are not failing with the udio fixes landed.

[Peter Jones]

As per discussion on the LWG call today, moving tickets that do not appear to be essential to fix version 2.17. If the fix lands before code freeze we will update the fix version to reflect that but we want to focus on activities on the critical path. Please speak up if you think that this issue definitely needs to be fixed before we could issue a 2.16 release.

[Peter Jones]

According to a comment from Patrick in the above changeset it was rolled into the RHEL 9.4 server support patch which has been merged. So is there anything still remaining to be tracked by this ticket?

"Patrick Farrell <[e-mail]>" uploaded a new patch: https://review.whamcloud.com/c/fs/lustre-release/+/55650
Subject: LU-17927 tests: remove dio always_except for el9.4
Project: fs/lustre-release
Branch: master
Current Patch Set: 1
Commit: 1c61d064db37b31bb0e1f7409435efc885b7f992

Depending on which patch is landing first, the always_except for test_119 should be removed either from https://review.whamcloud.com/54712 or by one of the UDIO patches.

[Shaun Tancheff]

fwiw:
https://review.whamcloud.com/c/fs/lustre-release/+/53997
and
https://review.whamcloud.com/c/fs/lustre-release/+/52266
are probably both needed for el9.4, the later needed an el9.4 specific fix.

Without the above patches el9.4 crashes, with the patches all the 119 series tests pass.

[Andreas Dilger]

paf, stancheff, this seems like a blocker for UDIO in 2.16.0 if this is failing consistently with el9.4.

Is this addressed by Shaun's in-flight UDIO fix patch in LU-17525, or is there something new in the el9.4 kernel that is causing problems for UDIO?

[Jian Yu]

sanity test 119f, 119g, and 119h hit the similar failure.
