My Cluster is configured in an Active/Passive configuration. When there is a problem with the active node and the attempt is made to failover, there is a failure to relocate the service. Please see below.

Is there a solution to this?

it woun't relocate because it can't unmount the filesystem. The "manual intervention is needed" line is there so that you know that you need to do manual stuff (eg. unmount the nfs-filesystem) before relocating.

Check to see if any process on the cluster node is using the filesystem - check for open files or processes with a current directory within the filesystem using "lsof".

NFS is still capable of totally hanging a system, to the point that a reboot is the only solution.

A force unmount is being done to relocate the NFS service. Will this be sufficient to prevent the unmount from failing?

In my experience, no not all the times.

But it will behave better.
