This is usually what happens when you have an underlying xfs file system 
as your backing store, and have had a failure which has shut the xfs 
file system down.

Have a look in dmesg for the servers, and see if xfs has shut down.

Reasons for xfs shutdown include a) bugs in xfs/kernel, b) storage 
device/RAID failure.

Our experience is that "b" happens far more often than "a", though "a" 
does happen (especially on some kernels).
