Description

This issue was created by maloo for Olaf Faaland <[e-mail]>

This issue relates to the following test suite run: https://testing.whamcloud.com/test_sets/150c0a5d-19ca-4d0e-bbd4-5d98ae175f9a

test_300d failed with the following error:

create 10 files failed

I can locally reproduce reliably with:
FSTYPE=zfs (zfs-0.7.11 or zfs-0.8.3)
MDSCOUNT=2
lustre 2.12.4, 2.13.0, and master
Run 20 times: sudo lustre/tests/auster sanity --only 300

I've seen the issue on average about 15% of runs with zfs-0.8 and less often with zfs-0.7.11

I've reproduced the issue with lustre 2.12.4, 2.13.0, master, and master-next.
Earlier lustre versions reliably LBUG before getting this far in test_300, in this configuration, so I don't know if the bug existed in earlier versions.

There are no warnings or errors in dmesg, emitted while the test is running (on any node).
