[Linux-cluster] really reliable?

[Spencer Parker]

I have a 2 node cluster dedicated to just mysql...the only problem I have is
when I want to add an NFS mount into the mix.  I just can't seem to get the
NFS mount to work properly.  When it does a status check it error out every
time on me and then stops.  Any insight into this?
