Split devices off a ZFS storage pool creating a new pool
pool newpool [device]...
-R root] pool
newpool [device ...]
- 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
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.
- Display vdev GUIDs instead of the normal device names. These GUIDs can
be used in place of device names for the zpool
- 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.
- 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.
- Do dry run, do not actually perform the split. Print out the expected
configuration of newpool.
- Display full paths for vdevs instead of only the last component of the
path. This can be used in conjunction with the
- Sets the specified property for newpool. See the
zpoolprops manual page for more information on the
available pool properties.
- Set altroot for newpool to
root and automatically import it.
