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

            Specifies that the output should be in list format.

       -q

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

            file system type.

            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.

       -v VfsType

            Reports on all file systems of a specified type.

            lsfs

       2    To show all file systems of vfs type jfs, enter: lsfs -v jfs

       3    To show the file system size, the fragment size, the compression algorithm (if any), and the number of bytes per i-node as

            recorded in the superblock of the root file system, enter: lsfs -q /

       /etc/filesystems

            Lists the known file systems and defines their characteristics.
