XFS file systems can be created with mkfs on any EVMS or compatibility volume that does not already have a file system. The following options are available for creating XFS file systems:
Specify a volume label for the file system. The default is none.
Specify the volume to use for an external journal. The default is none.
Specify the inline log size (in MB). This option is only available if the journalvol option is not set. The default is 4 MB; the allowed range is 2 to 256 MB.
