  Benefits of the solution:
  A mount without required options now fail with an
  error, instead of crashing the node.
  
  Work Around:
  Always have the required dev= mount
  option available. This is the
  default in /etc/fstab.
  
  Problem trigger:
  Issue a mount request where the
  dev= option is missing. Either remove
  that from /etc/fstab, or issue a
  mount command that does not read
  options from /etc/fstab, e.g.:
  mount -t gpfs /gpfs/fs1 /gpfs/fs1
