This failure is being tracked under LU-5761.

It happened only once in these many tests recently. Let's see how it goes.

[Andreas Dilger]

Jinshan, I strongly suspect that if this ancient issue is being seen again that it is a new issue that needs a new Jira ticket, even if the error message is the same. It is also most likely that the problem is FLR related, since this hasn't been reported in over 3 years.

This problem is seeing again at:

[Andreas Dilger]

Note that the ORI project is closed and those tickets cannot be used to land patches on master. I opened LU-5761 for tracking the ZFS issue.

[Yang Sheng]

I think this ticket is for ldiskfs issue. ZFS has similar issue but it shows more blocks leak and OR-412 is more proper to handle it. So i close this one first.

[Andreas Dilger]

This is still failing for ZFS so the above patch only re-enables test_89 for ldiskfs:

re-enable test patch: http://review.whamcloud.com/12227

[Andreas Dilger]

replay-single test_89 is still being skipped on ZFS due to this bug. It looks like the landed patch may resolve the test failure, so a patch to re-enable it should be submitted.

[Yang Sheng]

Patch landed. Close bug.
