mkfs.jfs(8) JFS file system creation mkfs.jfs(8)NAME
mkfs.jfs - create a JFS formatted partition
SYNOPSIS
mkfs.jfs [options] device
DESCRIPTION
mkfs.jfs is used to create (format) a JFS partition. mkfs.jfs must be run as root.
device is the special file name corresponding to the actual device (e.g. /dev/hdb1) on which a JFS file system will be created.
The default block size is 4096.
WARNING
mkfs.jfs will destroy all data on the specified device!
OPTIONS -c Check the device for bad blocks before building the file system.
-L volume_label
Set the volume label for the file system.
-O Provide case-insensitive support for compatibility with OS/2.
-q Quiet execution - do not ask for confirmation before creating the file system.
-s log_size
Set the log size (in megabytes). If the -s option is not used, the default log size is 0.4% of the aggregate size.
-V Print version information and exit (regardless of any other chosen options).
EXAMPLES
Format 3rd partition on 2nd hard disk with the volume label "JFS_hdb3":
mkfs.jfs -L JFS_hdb3 /dev/hdb3
Format 5th partition on 1st hard disk, verifying each block created:
mkfs.jfs -c /dev/hda5
