mmlsfs – Displays file system attributes.
Synopsis
mmlsfs {Device | all} [-A] [-a] [-B] [-D] [-d] [-E] [-F] [-f] [-I] [-i] [-j] [-k] [-M] [-m] [-n] [-o] [-P] [-Q] [-R] [-r] [-S]

Description
Use the mmlsfs command to list the attributes of a file system.
Depending on your configuration, additional information that is set by GPFS may be displayed to assist in
problem determination when contacting the IBM Support Center.
Results
If you do not specify any options, all attributes of the file system are displayed. When you specify options,
only those attributes specified are listed, in the order issued in the command. Some parameters are preset
for optimum performance and, although they display in the mmlsfs command output, you cannot change
them.
Parameters
Device | all The device name of the file system to be listed. File system names need not be
fully-qualified. fs0 is as acceptable as /dev/fs0. Specify all to list the attributes of all GPFS
file systems that are owned by this cluster, as well as all remote file systems to which this
cluster has access.
Options
This must be the first parameter.
-A Automatically mount the file system when the GPFS daemon starts
-a Estimated average file size, in bytes
-B Size of data block, in bytes
-D The type of file locking semantics that are in effect (nfs4 or posix)
-d Names of all of the disks in the file system
-E Exact mtime values reported
-F Maximum number of files currently supported
