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
keylocation=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 a dry-run (“No-op”) split: do not actually perform it.
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(7) manual page for more
information on the available pool properties.
-R
root- Set altroot for
newpool to
root and automatically import it.
