Thank you! Everything appears to be fine then, except that we cannot mount an OCFS2 filesystem on our 2nd node. When I try to mount the fs using ocfs2console on the 2nd node, I receive this error message in a dialog box: "mount.ocfs2: Invalid argument while mounting /dev/sda on /oracle_home. Check 'dmesg' for more information on this error. : Could not mount /dev/sda"
I do not see any related messages in /var/log/dmesg. Any help is greatly appreciated. Thanks, Reid The O2CB status is as follows on this 2nd node: [r...@nyclx2 ~]# lsmod | grep ocfs2 ocfs2 369640 0 ocfs2_dlmfs 55952 1 ocfs2_dlm 217104 2 ocfs2,ocfs2_dlmfs ocfs2_nodemanager 225416 6 ocfs2,ocfs2_dlmfs,ocfs2_dlm configfs 62301 2 ocfs2_nodemanager jbd 93873 2 ocfs2,ext3 [r...@nyclx2 ~]# service o2cb status Driver for "configfs": Loaded Filesystem "configfs": Mounted Driver for "ocfs2_dlmfs": Loaded Filesystem "ocfs2_dlmfs": Mounted Checking O2CB cluster tiaa: Online Heartbeat dead threshold: 31 Network idle timeout: 30000 Network keepalive delay: 2000 Network reconnect delay: 2000 Checking O2CB heartbeat: Not active [r...@nyclx2 ~]# -----Original Message----- From: Sunil Mushran [mailto:sunil.mush...@oracle.com] Sent: Tuesday, April 28, 2009 5:34 PM To: McKinley, Reid Cc: ocfs2-users@oss.oracle.com Subject: Re: [Ocfs2-users] O2CB heartbeat: Not active McKinley, Reid wrote: > > We have installed OCFS2 1.4.1 and for some reason we can only get the > mount point mounted on 1 of 2 nodes.

Is that volume mounted on the second node? Or is your qs, the mount on the second node is failing. For that I would suggest you check cluster.conf to ensure that the ip addresses are correct. Also, suggest either shutting down iptables or adding rules to allow traffic on the private network. Look for any firewalls between the nodes. dmesg should have more information. In short, cluster mount requires the nodes to connect to each other. > Also, should we be concerned that the ocfs2_nodemanager does not show > in this status?

The output of the o2cb init script in 1.4 is slightly different than 1.2. (You could do lsmod to check if the module is loaded or not.) $ lsmod | grep ocfs2 ocfs2_dlmfs 23944 1 ocfs2_dlm 176916 1 ocfs2_dlmfs ocfs2_nodemanager 141044 103 ocfs2_dlmfs,ocfs2_dlm configfs 28753 2 ocfs2_nodemanager ******************************************************************************************** This message, including any attachments, contains confidential information intended for a specific individual and purpose, and is protected by law.
