Determining which nodes have a file system mounted

The mmlsmount command is used to determine which nodes have a given file system mounted. The name and IP address of each node that has the file system mounted is displayed. This command can be used for all file systems, all remotely mounted file systems, or file systems mounted on nodes of certain clusters.

Note that the mmlsmount -L command reports file systems that are in use at the time the command is issued. A file system is considered to be in use if it is explicitly mounted with the mount or mmmount command or if it is mounted internally for the purposes of running some other GPFS™ command. For example, when you run the mmrestripefs command, the file system will be internally mounted for the duration of the command. If mmlsmount is issued in the interim, the file system will be reported as being in use by the mmlsmount command but, unless it is explicitly mounted, will not show up in the output of the mount or df commands. For more details, see The mmlsmount command..

This is an example of a mmlsmount -L command for a mounted file system named fs1:
File system fs1 (mnsd.cluster:fs1) is mounted on 5 nodes:
  9.114.132.101   c5n101                          mnsd.cluster
  9.114.132.100   c5n100                          mnsd.cluster
  9.114.132.106   c5n106                          mnsd.cluster
  9.114.132.97    c5n97                           cluster1.cluster
  9.114.132.92    c5n92                           cluster1.cluster
