I'm assuming that at least one of the filesystems you're referring to on 
the backend holds your recordings?  If so, how could you be watching tv 
one minute (LiveTV through mythfrontend, or a recording, but you're not 
specific on this), and then the next minute all your recording files are 
missing?

Maybe your arrays are simply not mounted, and you're seeing the empty 
directory where they would normally be mounted?

Or your permissions on the mount point got messed up somehow?

What's the output of "df -h" say?
