DESCRIPTION

24       systemd-makefs@.service, systemd-mkswap@.service,
25       systemd-growfs@.service, and systemd-growfs-root.service are used to
26       implement the x-systemd.makefs and x-systemd.growfs options in
27       fstab(5), see systemd.mount(5). They are instantiated for each device
28       for which the file system or swap structure needs to be initialized,
29       and for each mount point where the file system needs to be grown.
30
31       These services are started at boot, either right before or right after
32       the mount point or swap device are used.
33
34       systemd-makefs knows very little about specific file systems and swap
35       devices, and after checking that the block device does not already
36       contain a file system or other content, it will execute binaries
37       specific to each filesystem type (/sbin/mkfs.type or /sbin/mkswap). For
38       certain file system types (currently ext2/ext3/ext4(5), btrfs(5),
39       xfs(5), f2fs, vfat) and for swap devices, it will configure reasonable
40       defaults and set the file system label and UUID based on the device
41       name.
42
43       systemd-growfs knows very little about specific file systems and swap
44       devices, and will instruct the kernel to grow the mounted filesystem to
45       full size of the underlying block device. Nevertheless, it needs to
46       know the ioctl(2) number specific to each file system, so only certain
47       types are supported. Currently: ext4(5), btrfs(5), xfs(5), and dm-crypt
48       partitions (see cryptsetup(8)).
49
50       If the creation of a file system or swap device fails, the mount point
51       or swap is failed too. If the growing of a file system fails, a warning
52       is emitted.
