lsfs Command

Purpose

       Displays the characteristics of file systems.

Syntax

       lsfs [ -q ] [ -c | -l ] [ -a | -v VfsType | -u MountGroup| [FileSystem...] ]

Description

       The lsfs command displays characteristics of file systems, such as mount points, automatic mounts, permissions, and file system
       size. The FileSystem parameter reports on a specific file system. The following subsets can be queried for a listing of
       characteristics:
       *    All file systems
       *    All file systems of a certain mount group
       *    All file systems of a certain virtual file system type
       *    One or more individual file systems

       The lsfs command displays additional Journaled File System (JFS) or Enhanced Journaled File System (JFS2) characteristics if
       the -q flag is specified.

       You can use a Web-based System Manager File Systems application (wsm fs fast path) to run this command. You could also use the
       System Management Interface Tool (SMIT) smit lsfs fast path to run this command.

Flags

       -a
            Lists all file systems (default).
       -c
            Specifies that the output should be in colon format.
       -l

       -q
            Displays additional Journaled File System (JFS) or Enhanced Journaled File System (JFS2) characteristics specific to the

            This information is not reported for other virtual file system types. It is displayed in addition to other file system
            characteristics reported by the lsfs command.
       -u MountGroup
            Reports on all file systems of a specified mount group.
