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.
