19#  Mount GPFS file systems on one or more nodes in the cluster.
20#
21#  Usage:
22#    mmmount {Device | DefaultMountPoint | all} [-o MountOptions]
23#            [-a | -N {Node[,Node...] | NodeFile | NodeClass}]
24#  or
25#    mmmount Device MountPoint [-o MountOptions]
26#            [-a | -N {Node[,Node...] | NodeFile | NodeClass}]
27#
28#  where:
29#    -a                Mount the file systems on all nodes in the cluster.
30#
31#    -N Node,Node,...  Specify the nodes on which the mount is to take place.
32#    -N NodeFile       NodeClass may be one of several possible node classes
33#    -N NodeClass      (e.g., quorumnodes, managernodes, nsdnodes, etc.)
34#
35#    -o MountOptions   is a comma-separated list of mount options.
36#
37#  If not explicitly-specified otherwise, the file systems are mounted on
38#  the local node only.
39#
40#
41# Undocumented option:
42#
43#   -y                 Suppress internal remounting.
