Determining which nodes have a file system mounted

The mmlsmount command is used to determine which nodes have a specific 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.

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 when it is explicitly mounted with the mount or mmmount command, or when it is mounted internally for the purposes of running some other GPFS command. For example, when you run the mmrestripefs command, the file system remains internally mounted during that time. If the mmlsmount command is issued in the interim, then the file system is reported as in use by the mmlsmount command. However, unless the file system is explicitly mounted, it does not show up in the output of the mount or df commands. For more information, see The mmlsmount command.

This is an example of a mmlsmount -L command for a mounted file system that is 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
