CMAN and Openais upgrade steps

Latest response

Hi,

We have two node cluster (RHEL 5.6). Recently cluster went into split brain state and rebooted automatically to fix the issue.

When searched on this, found that there is bug in cman and openais and it needs to be updated to its latest version.

I would need the steps to upgrade CMAN and openais to its latest version in RHEL 5.6.

I would relocate the resources to avoid downtime. Is yum update better or rpm upgrade is better. If any one can share a document for best steps to proceed ahead.

Thanks
