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.
