If it is no longer happening I think that it should be enough to close it as cannot repro and we can reopen the ticket if it is seen again.

The Maloo searching result shows that LU-3625 has disappeared since Aug.7 (probably fixed by some commit)? And the other issue on replay-single.sh test_58b/c(No such attribute) in LU-3795 was fixed in Sep.11.

Could we lower priority of this bug?

[Andreas Dilger]

We would still like some investigation of the source of the problem even if the failure is only on ZFS. Did this start failing at a certain time, maybe related to some patch introducing a regression?

[Emoly Liu]

This failure for ldiskfs hasn't been seen in recent one month, but it still happens for zfs, so I add label "zfs".

[Peter Jones]

Emoly will look into this one

I will use those 6 tar files as my sample data for repopulating the database tomorrow (2013 09 05). If it goes well then I will be trickling the data in for all the holes for the 6 weeks leading up to the maloo failure (2013 08 24).
