I have a two node cluster on RHEL5 with 2.0.52 version of clustering that appears to be operating normally however, I cannot run the pvdisplay command: [root@server1 ~]# pvdisplay Error locking on node server2: Command timed out Error locking on node server1: Command timed out Unable to obtain global lock. I then run this command but it just hangs after displaying this output: [root@server1 ~]# /etc/init.d/clvmd status clvmd (pid 16888 8497) is running... Here's clustat: Cluster Status for server @ Sat Mar 19 14:30:05 2011 Member Status: Quorate Member Name ID Status ------ ---- ---- ------ server1 1 Online, Local, rgmanager server2 2 Online, rgmanager Service Name Owner (Last) State ------- ---- ----- ------ ----- service:server-nfs-a server1 started service:server-nfs-b server2 started service:server-nfs-c server1 started service:server-nfs-h server2 started service:server-nfs-i server2 started service:postgresql server1 started Not sure where to begin troubleshooting this. Any ideas? -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
