Lon, The problem is reproducible at will. I do have access to the system after the "shutdown -h now" command is issued and rgmanager blocks. I have gdb installed, but I do not know how to obtain rgmanager-debuginfo. The system is on an isolated network and I pointed you to an on-disk repository that is a copy of the RHEL6 distribution DVD copied to local disk.

If you can still reach the machine (ssh or whatever) after executing 'shutdown -h now': 1) Install 'rgmanager-debuginfo' and gdb. 2) When rgmanager hangs on shutdown, run: - gdb /usr/sbin/rgmanager `pidof -s rgmanager` 3) When inside gdb, run: - thr a a bt There's a related bug in RHEL5 related to releasing the lockspace if CMAN exits before rgmanager, but I was unable to reproduce it on the STABLE3/31 branches when I tested. -- Lon -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
