NAME

mke2fs - create a Linux second extended file system  

SYNOPSIS

mke2fs [ -c | -t | -l filename ] [ -b block-size ] [ -f fragment-size ] [ -i bytes-per-inode ] [ -m reserved-blocks-percentage ] [ -v ] device [ blocks-count ]  

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.
