Description

This issue was created by maloo for Andreas Dilger <[e-mail]>

This issue relates to the following test suite run: https://testing.hpdd.intel.com/test_sets/56e1b56e-53ff-11e5-8f2c-5254006e85c2.

The sub-test test_70d failed with the following error:

error on LL_IOC_LMV_SETSTRIPE '/mnt/lustre/d70d.replay-single/test1' (3): stripe already set
error: mkdir: create stripe dir '/mnt/lustre/d70d.replay-single/test1' failed
mkdir fails
/usr/lib64/lustre/tests/replay-single.sh: line 2236: kill: (25189) - No such process
mkdir/rmdir 25189 stopped

There are several test failures and timeouts for 70d since 2015-09-02 so I suspect a patch landed on that day or the previous day that introduced a regression.

Info required for matching: replay-single 70d

Never mind, I see that http://review.whamcloud.com/21064 "LU-7117 mdt: mdt unlink should lock before lookup" is abandoned since it was landed as http://review.whamcloud.com/21088 via LU-8353.

[Andreas Dilger]

How do the patches http://review.whamcloud.com/20940 "LU-7117 osp: control RPC to be sent when recovery" and http://review.whamcloud.com/21064 "LU-7117 mdt: mdt unlink should lock before lookup" relate to each other? Are they both needed? Are they different approaches to fixing the same problem, and only one is needed?
