I have been trying to set up a pair of servers in a secure environment. They both run and switch over from each other ok. (RHEL5.4) However the nfs is not being shared in a common dir. When I move nfs to the shared drive, at switch over I get an error saying Could not unmount file I think this is due to nfs residing on the drive. The server ends up doing a reboot. I end up with a stale mount on the client at the moment. Looking at the scheme this is what I would have expected. Is there another solution or am I doing something wrong?
