Polecenie mke2fs

Wykonanie, użycie: 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

Opcje wykonania mke2fs w konsoli

-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 volume label, or by UUID.
-l filename

Consult filename for a list of bad blocks.

 -L label

Set volume label for filesystem.

 -m percentage

Reserve percentage percent of the blocks for use by privileged users.

 -M directory

Set the last mounted directory for filesystem to directory.

 -n

Don't create the filesystem; just show what would happen if it were run. This option is overridden by -F.

 -N inodes

Specify number of inodes to reserve for filesystem. By default, this number is calculated from the number of blocks and the inode size.

 -o os

Set filesystem operating system type to os. The default value is usually Linux.

 -O featurelist

Use specified featurelist to create filesystem. The sparse_super and filetype features are used by default on kernels 2.2 and later. The following parameters may be given in a comma-separated list:

dir_index

Use hashed B-trees to index directories.

 filetype

Store file type information in directory entries.

 has_journal

Create an ext3 journal. Same as using the -j option.

 journal_dev

Prepare an external journaling device by creating an ext3 journal on device instead of formatting it.

 sparse_super

Save space on a large filesystem by creating fewer superblock backup copies.
-q

Quiet mode.

 -r revision

Set filesystem revision number to revision.

 -S

Write only superblock and group descriptors; suppress writing of inode table and block and inode bitmaps. Useful only when attempting to salvage damaged systems.

 -T use

Set bytes-per-inode based on the intended use of the filesystem. Supported filesystem types are:

news

Four kilobytes per inode.

 largefile

One megabyte per inode.

 largefile4

Four megabytes per inode.
-v

Verbose mode.

 -V

Print version number, then exit.
