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.
