Hi all, 

I am unmounting an OCFS2 filesystem across our cluster, but on 2 nodes
it just hangs.

This is on RHEL 4 update 8 kernel 2.6.9-89.0.26.ELsmp   running OCFS2
version OCFS2 1.2.9 Thu Sep  8 23:05:45 PDT 2011 (build
e5c3135c8cbf75f2620ff4c782d634f1)

If I do a mount | grep ocfs I get the following (which is what I expect)

# mount | grep ocfs

ocfs2_dlmfs on /dlm type ocfs2_dlmfs (rw)

/dev/emcpowerq1 on /d00/cfs type ocfs2 (rw,_netdev,heartbeat=local)

 

 

In /var/log/messages there are no error messages or any messages
relating to unmounting this particular filesystem.

Other OCFS2 mounted filesystems have umounted OK.


What steps should I take to diagnose what is causing this to hang?

 

Many thanks,

Neil
