DESCRIPTION
mke2fs
is used to create a Linux second extended file system on a device (usually
a disk partition).
device
is the special file corresponding to the device (e.g /dev/hdXX).
blocks-count
is the number of blocks on the device. If omitted,
mke2fs
automagically figures the file system size.
OPTIONS
- -b block-size
-
Specify the size of blocks in bytes.
- -c
-
Check the device for bad blocks before creating the file system.
- -f fragment-size
-
Specify the size of fragments in bytes.
- -i bytes-per-inode
-
Specify the bytes/inode ratio.
mke2fs
creates an inode for every
bytes-per-inode
bytes of space on the disk. This value defaults to 4096 bytes.
bytes-per-inode
must be at least 1024.
- -l filename
-
Read the bad blocks list from
filename
.
- -m reserved-blocks-percentage
-
Specify the percentage of reserved blocks for the super-user. This value
defaults to 5%.
- -t
-
Check the device for bad blocks before creating the file system.
- -v
-
Verbose execution.
AUTHOR
mke2fs
is based on
mkefs(8)
which is based itself on
mkfs(8)
written by Linus Torvalds <torvalds@cs.helsinki.fi> for the
minix file system.
Remy Card <card@masi.ibp.fr> has adapted it to the second extended file
system and is maintaining it.
Adam Richter <adam@soda.berkeley.edu> added the automatic file system
size detection.
BUGS
mke2fs
accepts the -b and -f option but currently ignores them because the second
extended file system does not support variable block sizes nor fragments
yet.
There may be some other ones. Please, report them to the author.
AVAILABILITY
mke2fs
is available for anonymous ftp from ftp.ibp.fr (132.227.60.2) in
/pub/linux/BETA/ext2fs.
