SYSTEMD-MAKEFS@.SERVICE(8) systemd-makefs@.service SYSTEMD-MAKEFS@.SERVICE(8)
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), 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).
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.
