lsfs

lsfs Command (AIX)



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) characteristics
if the -q flag is specified.

You can use the System Management Interface Tool (SMIT) to run this
command. To use SMIT, enter:

smit lsfs

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	Queries the logical volume manager (LVM) for the logical volume
size (in 512-byte blocks) and queries the JFS superblock for the file
system size, the fragment size, the compression algorithm (if any),
and the number of bytes per i-node (nbpi).

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.

Examples

1.	To show all file systems in the /etc/filesystems file, enter:

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 /

Files

/etc/filesystems	Lists the known file systems and defines their characteristics.
