device
DESCRIPTION
mkfs.nilfs2 is used to create a nilfs2 filesystem (usually in a disk
partition). device is the special file corresponding to the device
(e.g. /dev/sdXX). Usually mkfs.nilfs2 is invoked from the mkfs(8)
front-end program.
The exit code returned by mkfs.nilfs2 is 0 on success and 1 on failure.
OPTIONS
-b block-size
Specify the size of blocks in bytes. The valid block size is
1024, 2048, 4096, 8192 bytes, ..., and the maximum block size is
restricted to the system page size. For most machines, it is
4096 bytes. The default block size is 4096 bytes.
-B blocks-per-segment
Specify the number of blocks in a segment, where the segment
(also called full segment) is an allocation unit of disk space
of NILFS. This parameter gives the size of segment and
consequently determines how many segments are aligned in the
specified device. The default number of blocks per segment is
2048 (= 8MB with 4KB blocks).
-c Check the device for bad blocks before building the filesystem.
-L new-volume-label
Set the volume label for the filesystem to new-volume-label.
The maximum length of the volume label is 16 bytes.
-m reserved-segments-percentage
Specify the percentage of the segments reserved for garbage
collection. The default percentage is 5%.
-n Cause mkfs.nilfs2 to not actually create a filesystem, but
display what it would be do if it were to create a filesystem.
-q Quiet execution. Useful if mkfs.nilfs2 is run in a script.
-V Print the version number of mkfs.nilfs2 and exit.
