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
