IBM General Parallel File System for AIX: Administration and Programming Reference

Listing file system attributes

Use the mmlsfs command to display the current file system attributes:

-a

Estimated average file size, in bytes

-A

Automatically mount the file system when the GPFS daemon starts

-B

Size of data blocks, in bytes

-C

Identifier of the GPFS nodeset to which the file system belongs

-d

Names of all of the disks in the file system

-f

Minimum fragment size, in bytes

-F

Maximum number of files currently supported

-i

Inode size, in bytes

-I

Indirect block size, in bytes

-m

Default number of metadata replicas

-M

Maximum number of metadata replicas

-n

The estimated number of nodes that will mount the file system

-Q

Which quotas are currently enforced on the file system

-r

Default number of data replicas

-R

Maximum number of data replicas

-V

Current format version of the file system

-z

Whether or not DMAPI is enabled for the file system

If you specify no options with the mmlsfs command, all file system attributes are listed.

For example, to list the expected average file size for the file system fs1, enter:

mmlsfs fs1 -a 

The system displays information similar to:

flag value          description
---- -------------- -------------------------------------------------------
-a   208965994      Estimated average file size
  
 

See the mmlsfs Command for complete usage information. See the IBM General Parallel File System for AIX: Concepts, Planning, and Installation Guide and search on GPFS architecture and file system creation considerations for a detailed discussion of file system attributes.
