== File System Format Commands ==

Linux provides commands to create a filesystem. They are all based on mkfs

<syntaxhighlight>
mkfs.ext
mkfs.ext2
mkfs.ext3
mkfs.ext4
mkfs.xfs
</syntaxhighlight>

To create a file system, make sure that the partition is umounted and then run the mkfs command

<syntaxhighlight>
mkfs.ext4 /dev/sdb1
mkfs -t ext4 /dev/sdb1
</syntaxhighlight>

=== Swap Volumes ===

The mkswap command is used to format a swap parition. But then it must be activated using the swapon command.

== File System Check Commands ==

To check a filesystem and perform any repairs needed use the fsck command. To do this umount the file system, this may require you to boot into single user mode.

== File System Conversion Commands ==

To convert a file system from ext2 to ext3 for example, it must be remounted as read only before adding the journaling using the tune2fs command.

<syntaxhighlight>
mount -o remount,ro /dev/vda1
tune2fs -j /dev/vda1
mount -o remount,rw /dev/vda1
</syntaxhighlight>

To move to ext4, some other features must be added.

<syntaxhighlight>
mount -o remount,ro /dev/vda1
tune2fs -O extent,uninit_bg,dir_index /dev/vda1
mount -o remount,rw /dev/vda1
</syntaxhighlight>
