The auto-tests failures that experienced patch-set #8 of http://review.whamcloud.com/7437 under DNE conditions are not related to itself but are due to the issue addressed in LU-4093 where orphan HSM requests prevents others to start. And on the other hand, since this condition can clear itself during a test-suite, the sub-tests modified by this patch to become "DNE-aware" ran successfully !!

Auto-tests failures of Change #7571 patch-set #7 are DNE-specific and I will provide an update about them soon.

sanity-hsm subtests test_301/test_302 failed during Change #7437 patch-set #8 auto-tests DNE session.

sanity-hsm subtests test_302/test_400/test_401/test_403/test_404 failed during Change #7571 patch-set #7 auto-tests DNE-specifc session.

Need to analyze Maloo errors reports.

Thanks Thomas !! That will greatly help to clarify and not to get Gerrit changes orphaned.

This ticket is now referenced in the commit message for changes http://review.whamcloud.com/7437 and http://review.whamcloud.com/7571.
The following test parameters have also been set for both of them, as they only modify sanity-hsm.sh:
"Test-Parameters: mdtcount=2 mdscount=2 testlist=sanity-hsm"

Hello Thomas,

Thanks to add the "Test-Parameters: mdtcount=2 mdscount=2" added in Commit-msg.

But I also have an other request, in order to clarify the JIRA-Ticket<->Gerrit-Change relationships, could it be possible that you change Commit-msg of http://review.whamcloud.com/7437 and refer to this ticket instead of LU-3561 ??

Thanks again and in advance for your help.

Thomas,

Can you, as WangDi indicated, re-submit (+ re-base before ...) your change #7437/patch-set #3 with "Test-Parameters: mdtcount=2 mdscount=2" added in Commit-msg, to allow it being tested under DNE conditions.

Thanks!

I had to re-trigger auto-tests for both patches due to TEI-534 (aka no_root_squash for copy-tool back-end) related issue ...

[Thomas LEIBOVICI - CEA (Inactive)]

The following change depends on this patch: http://review.whamcloud.com/#/c/7571/ (DNE specific tests for HSM).

[Bruno Faccini (Inactive)]

I had to re-run auto-tests for the change due LU-1458 bug trigger during lustre-rsync-test/test_2b.

Here is the proposed patch for this change:
