Thanks, Emoly. Please, reopen if the problem reoccurs in the future.

[Emoly Liu]

Andrew, you are right. Sorry to reopen this one.

I searched Maloo test results in this link https://maloo.whamcloud.com/sub_tests/query?utf8=✓&test_set%5Btest_set_script_id%5D=f6a12204-32c3-11e0-a61c-52540025f9ae&sub_test%5Bsub_test_script_id%5D=fb022be0-32c3-11e0-a61c-52540025f9ae&sub_test%5Bstatus%5D=FAIL&sub_test%5Bquery_bugs%5D=&test_session%5Btest_host%5D=&test_session%5Btest_group%5D=&test_session%5Buser_id%5D=&test_session%5Bquery_date%5D=&test_session%5Bquery_recent_period%5D=&test_node%5Bos_type_id%5D=&test_node%5Bdistribution_type_id%5D=&test_node%5Barchitecture_type_id%5D=&test_node%5Bfile_system_type_id%5D=00437f32-318d-11e1-9c6d-5254004bbbd3&test_node%5Blustre_branch_id%5D=&test_node_network%5Bnetwork_type_id%5D=&commit=Update+results

I didn't check each one. Maybe you are right, their parent commit is earlier than LU-3669 fix. If so, please close this ticket and ignore my previous comments.

The fixes were landed on Sep, 11 (see http://review.whamcloud.com/#/c/7208/), not two months ago.

It's not clear whether your reports are based on sources more recent than of that date.

https://maloo.whamcloud.com/test_sets/5bb89698-1a4f-11e3-a95b-52540035b04c was ran on Sep 10.
https://maloo.whamcloud.com/test_sets/243e1cd2-24f0-11e3-839b-52540035b04c was ran on Sep 23, the build links to http://review.whamcloud.com/#/c/7584/, which appears to be Patch Set 8 or earlier (Patch set 9 was uploaded on Sep 25) and the parent commit for Patch set 8 is c0e6982b57319e5044cf12bee509c0c571a17cc5, which was landed on Aug 7.

I reopen this ticket because through investigation on LU-3625, I find still many zfs tests hit this error in recent two months, such as:
https://maloo.whamcloud.com/test_sets/b278ad30-24ac-11e3-93a0-52540035b04c
https://maloo.whamcloud.com/test_sets/243e1cd2-24f0-11e3-839b-52540035b04c
https://maloo.whamcloud.com/test_sets/54b1a140-22e3-11e3-9488-52540035b04c
https://maloo.whamcloud.com/test_sets/5bb89698-1a4f-11e3-a95b-52540035b04c

"No such attribute" happens much more frequently than "No such file or directory".

[Nathaniel Clark]

This is verified fixed by LU-3669 closure

Nathaniel

Please verify whether this is still an issue after LU-3669 fix has landed

The first (ZFS) report is a duplicate of LU-3713 which is fixed by http://review.whamcloud.com/7208 in the context of LU-3669.

The second report does not look xattr cache related (no traces of xattr operations either in the MDS or in the client debug logs), "No such file or directory" probably relates to the fact that there was no such file or directory, rather than an xattr failure.

[Andreas Dilger]

This looks like it also failed on non-zfs testing:
https://maloo.whamcloud.com/sub_tests/749022be-07dd-11e3-bcfa-52540035b04c

and the first failure was on 2013-07-29 00:48:20 UTC
https://maloo.whamcloud.com/sub_tests/e2333076-f87a-11e2-a8b3-52540035b04c

and according to http://review.whamcloud.com/5537 the xattr cache patch landed on 07-29 also.
