[Linux-cluster] Filesystem repair on a Clustered-NFS Server



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Assume for a moment that you have an EL5 NFS Cluster.

You have a clustered service "nfs-server1" that has an IP resource and
several "child" filesystems tied to it so that the filesystems move
when the IP moves through the cluster.  Each of these child
filesystems has an nfs-export resource associated with it, so they are
nfs-exported automatically.

How do you repair one of those filesystems without taking down the
entire service?  You can't unmount it while it's exported, and if you
try to unexport/unmount manually the cluster restarts it for you...

Do you have to remove the failed filesystem from the service?  Or can
you "disable" one resource and leave the others in peace?

This is not entirely a rhetorical question for me,
