]- Splits devices off pool creating
newpool. All vdevs in
pool must be mirrors and the pool must
not be in the process of resilvering. At the time of the split,
newpool will be a replica of
pool. By default, the last device in each
mirror is split from pool to create
newpool.
The optional device specification causes the specified device(s) to be
included in the new pool and, should any
devices remain unspecified, the last device in each mirror is used as
would be by default.
-g- Display vdev GUIDs instead of the normal device names. These GUIDs can
be used in place of device names for the zpool
detach/offline/remove/replace commands.
-L- Display real paths for vdevs resolving all symbolic links. This can be
used to look up the current block device name regardless of the
/dev/disk/ path used to open
it.
-l- Indicates that this command will request encryption keys for all
encrypted datasets it attempts to mount as it is bringing the new pool
online. Note that if any datasets have a
keylocation of
prompt this command will block waiting
for the keys to be entered. Without this flag encrypted datasets will
be left unavailable until the keys are loaded.
-n- Do dry run, do not actually perform the split. Print out the expected
configuration of newpool.
-P- Display full paths for vdevs instead of only the last component of the
path. This can be used in conjunction with the
-L flag.
-o
property=value- Sets the specified property for
newpool. See the
zpoolprops manual page for more
information on the available pool properties.
-R
root- Set altroot for
newpool to
root and automatically import
it.
