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.

commit 702e5bc68ad2 ("ocfs2: use generic posix ACL infrastructure")
refactored code to use posix_acl_create. The problem with this function
is that it is not mindful of the cluster wide inode lock making it
unsuitable for use with ocfs2 inode creation with ACLs. For example,
when used in ocfs2_mkno
commit 743b5f1434f5 ("ocfs2: take inode lock in ocfs2_iop_set/get_acl()")
introduced this issue. ocfs2_setattr called by chmod command holds cluster
wide inode lock when calling posix_acl_chmod. This latter function in turn
calls ocfs2_iop_get_acl and ocfs2_iop_set_acl. These two are also called
Hi,
These two patches is to fix recursive locking deadlock issues. As we
talked with Mark before, recursive locking is not allowed in ocfs2,
so these two patches fixes the deadlock issue with reverting back
patches to avoid recursive locking. Please review.
Thanks,
Junxiao.
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 k
