## NAME
       systemd-makefs@.service, systemd-mkswap@.service, systemd-growfs@.service, systemd-makefs,
       systemd-growfs - Creating and growing file systems on demand

## SYNOPSIS
       <systemd-makefs@_device_.service>

       <systemd-mkswap@_device_.service>

       <systemd-growfs@_mountpoint_.service>

       /lib/systemd/systemd-makefs

       /lib/systemd/systemd-growfs

## DESCRIPTION
       systemd-makefs@.service, systemd-mkswap@.service, and systemd-growfs@.service are used to
       implement the **x-systemd.makefs** and **x-systemd.growfs** options in [**fstab**(5)](https://www.chedong.com/phpMan.php/man/fstab/5/markdown), see
       [**systemd.mount**(5)](https://www.chedong.com/phpMan.php/man/systemd.mount/5/markdown). They are instantiated for each device for which the file system or swap
       structure needs to be initialized, and for each mount point where the file system needs to be
       grown.

       These services are started at boot, either right before or right after the mount point or
       swap device are used.

       systemd-makefs knows very little about specific file systems and swap devices, and after
       checking that the block device does not already contain a file system or other content, it
       will execute binaries specific to each filesystem type (/sbin/mkfs._type_ or /sbin/mkswap).

       systemd-growfs knows very little about specific file systems and swap devices, and will
       instruct the kernel to grow the mounted filesystem to full size of the underlying block
       device. Nevertheless, it needs to know the [**ioctl**(2)](https://www.chedong.com/phpMan.php/man/ioctl/2/markdown) number specific to each file system, so
       only certain types are supported. Currently: [**ext4**(5)](https://www.chedong.com/phpMan.php/man/ext4/5/markdown), [**btrfs**(5)](https://www.chedong.com/phpMan.php/man/btrfs/5/markdown), [**xfs**(5)](https://www.chedong.com/phpMan.php/man/xfs/5/markdown), and dm-crypt
       partitions (see [**cryptsetup**(8)](https://www.chedong.com/phpMan.php/man/cryptsetup/8/markdown)).

       If the creation of a file system or swap device fails, the mount point or swap is failed too.
       If the growing of a file system fails, a warning is emitted.
