Unable to create a clustered Linux volume

This document (7009516) is provided subject to the disclaimer at the end of this document.

Environment

Novell Cluster Services
Novell Open Enterprise Server 11 (OES 11) Linux

Situation

Unable to create a clustered Linux volume.
NSSMU - Error 23384: Device "/dev/sde" is not shared by clvm

CLVMD process does not load during cluster initialization.
Failed to get my node id.

Resolution

Workaround:
Update the nodename file by using the following command: "echo -n "$HOSTNAME" > /etc/opt/novell/ncs/nodename"
Restart clustering services. (rcnovell-ncs stop / start)

Important: All nodes in the cluster need to have /usr/sbin/clvmd process running. If one node in the cluster has a problem it will affect your ability to create any clustered linux volumes.

Fix: Fixed in novell-cluster-services-kmp-default RPM.
OES11SP1 and in September 2012 OES11 Maintenance update patch (oes11-September-2012-Scheduled-Maintenance)

Cause

Found that there was a carriage return after the hostname in clustering's file /etc/opt/novell/ncs/nodename which was causing clvmd to fail during initialization.

Using (/usr/bin/vi) VI editor to edit this file will add a carriage return after the $HOSTNAME which will cause this problem.

Additional Information

Check to see if the /usr/sbin/clvmd process is running. This process is started by Novell Clustering Services.
Example: ps -eaf | grep clvmd

/var/log/messages shows this after novell-ncs startup script has run.
clvmd[2470]: CLVMD started
clvmd[2470]: Entering _init_cluster.
clvmd[2470]: _init_cluster: ncs_fd = 7.
clvmd[2470]: _init_cluster: Failed to get my node id.
clvmd[2470]: Can't initialise cluster interface

Troubleshooting:
Turn on debug mode for clvmd.
Run the following command "/usr/sbin/clvmd -d" and then check output in /var/log/messages.
May increase the verbosity level if needed. "/usr/sbin/clvmd -d2"
