systemd-clonesetup remove NAME
systemd-clonesetup@.service
systemd-clonesetup is used to set up (with add) and tear down
(with remove) dm-clone devices. It is primarily used via
systemd-clonesetup@.service units generated from
/etc/clonetab by
systemd-clonesetup-generator(8).
The positional arguments NAME, SOURCE-DEVICE,
DEST-DEVICE, META-DEVICE, and OPTIONS
have the same meaning as the fields in
clonetab(5).
Currently, the supported option in OPTIONS is
region-size=BYTES, where
BYTES is measured in bytes (standard suffixes like
"K", "M", "G" are supported).
