 Description   

I got this failure while testing ptlrpc service patch, and don't think it could be introduced by my patch:

We saw this a couple of times in the past on the Orion branch.

Do you have time to look at this?

hm, don't see anything wrong in the logs ... any other recent occurrences?

This was b2_3 + "USE_OFD=yes" + "OSTFSTYPE=zfs".

Let's try to use multiop_bg_pause ...

Johann,
Is this a duplicate of LU-2877 which the patch looks very close to yours?

Comment by Peter Jones [ 06/Mar/13 ]

Johann confirms that this is a duplicate of LU-2877

Comment by Andreas Dilger [ 01/Oct/14 ]

sanity.sh test_34h is still being skipped due to this bug. It should have been fixed via LU-2877, so it needs a patch to re-enable the test.
