Synopsis
mke2fs [options]device[blocks] mkfs.ext2 [options]device[blocks]
System administration command. Format device as a Linux Second Extended Filesystem. You may specify the number of blocks on the device or allow mke2fs to guess.
Options
- -b block-size
Specify block size in bytes.
- -c
Scan device for bad blocks before execution.
- -E featurelist
Specify extended features. This option’s parameters may be given in a comma-separated list:
- stride=size
Configure filesystem for a RAID array. Set stride size to size blocks per stripe.
- resize=blocks
Reserve descriptor table space to grow filesystem to the specified number of blocks.
- -f fragment-size
Specify fragment size in bytes.
- -F
Force mke2fs to run even if filesystem is mounted or device is not a block special device. This option is probably best avoided.
- -i bytes-per-inode
Create an inode for each bytes-per-inode of space. bytes-per-inode must be 1024 or greater; it is 4096 by default.
- -j
Create an ext3 journal. This is the same as invoking mkfs.ext3.
- -J parameterlist
Use specified parameterlist to create an ext3 journal. The following two parameters may be given in a comma-separated list:
- size=journal-size
Create a journal of journal-size megabytes. The size may be between 1024 filesystem blocks and 102,400 filesystem blocks in size (e.g., 1–100 megabytes if using 1K blocks, 4–400 megabytes if using 4K blocks).
- device=journal-device
Use an external journal-device to hold the filesystem journal. The journal-device can be specified by name, by ...
