NAME

       systemd-makefs@.service, systemd-mkswap@.service, systemd-growfs@.service, systemd-growfs-
       root.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

       systemd-growfs-root.service

       /usr/lib/systemd/systemd-makefs

       /usr/lib/systemd/systemd-growfs

DESCRIPTION

       systemd-makefs@.service, systemd-mkswap@.service, systemd-growfs@.service, and
       systemd-growfs-root.service are used to implement the x-systemd.makefs and
       x-systemd.growfs options in fstab(5), see systemd.mount(5). 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).
       For certain file system types (currently ext2/ext3/ext4(5), btrfs(5), xfs(5), f2fs, vfat)
       and for swap devices, it will configure reasonable defaults and set the file system label
       and UUID based on the device name.

       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) number specific to each file system,
       so only certain types are supported. Currently: ext4(5), btrfs(5), xfs(5), and dm-crypt
       partitions (see cryptsetup(8)).

       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.
