19# Usage:
20#
21#   mmfsctl Device {suspend | resume}
22#     or
23#   mmfsctl Device {exclude | include}
24#                  {-d DiskList | -F DiskFile | -G FailureGroup}
25#     or
26#   mmfsctl Device syncFSconfig
27#                  {-n RemoteNodes | -C RemoteCluster} [-S SpecFile]
28#
29# where
30#
31#   Device            The device name of the affected GPFS file system.
32#
33#   suspend           Suspend the execution of all new I/O requests coming
34#                     from user applications, flush all pending requests
35#                     on all nodes, bring the file system to a consistent
36#                     state on disk.
37#
38#   resume            Resume normal processing of I/O requests on all nodes.
39#
40#   exclude           Exclude the specified disks when determining the
41#                     most recent file system control data structures.
42#                     This has the effect of overriding the normal GPFS
43#                     quorum requirements for on-disk file system data
44#                     and stops the disks from participating into normal
45#                     file systems operations.
46#
47#   include           Restore the specified disks for normal file system
48#                     operations.
49#
50#   -d DiskList       The names of the disks to be excluded or included.
51#                     If there is more than one disk, delimit each name with
52#                     a semicolon (;) and enclose the list in quotation marks.
53#
54#   -F DiskFile       A file that contains, one per line, the names of the
55#                     disks to be excluded or included.
56#
57#   -G FailureGroup   Exclude or include all disks that belong to the
58#                     specified failure group.
59#
60#   syncFSconfig      Synchronize the file system configuration information
61#                     in a remote cluster with the file system information
62#                     in the local cluster.
63#
64#   -C RemoteCluster  The name of the remote cluster where the file system
65#                     information is to be imported.  The cluster must
66#                     already be registered with the mmremotecluster command.
67#
68#   -n RemoteNodes    The path name to a file containing, one per line,
69#                     hostnames or IP addresses of nodes that belong to
70#                     the remote cluster.
71#
72#   -S SpecFile       The path name to a file with the NSD server designations
73#                     in the remote cluster for all affected disks.  The file
74#                     format is the same as for the -S parameter of mmimportfs.
75#                     Note that SpecFile refers to a file in the remote cluster
76#                     and must exist on all nodes in the contact node list.
