Hi all.
I built up ocfs2 on drbd dual primary.
Each node has 12 disks of Raid 10 with mdadm chuck size 4096k.
Cluster size of filesystem is 1048576 bytes.
Main purpose of use is reflink files on drbd.
I reflinked files from 1TB file and exported them to LIO iscsi.
After few days tests, i got kernel error.

A similiar issue was first reported by Junxiao:
[1] https://oss.oracle.com/pipermail/ocfs2-devel/2015-December/011408.html
I also reproduced that issue. But it's very tricky to handle in a way
maintainer can accept. There is a proposed patch in this thread, but I
fail to find the patches in archive:
[2] https://oss.oracle.com/pipermail/ocfs2-devel/2016-January/011503.html
IIRC, it just hung there, but without "-17" error which means "File
exists" :
(reflink,30902,0):ocfs2_reflink:4317 ERROR: status = -17

Hi Tiger,
Only those two process reported call trace from the two nodes? If so,
looks a little different from my hung where it is a recursive locking of
cluster lock. Any way, i just post the fixed to my issue to the mail
list, you can have a try.
Thanks,
Junxiao.
