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?
