zpool-split —
split devices off ZFS storage pool, creating new
pool
zpool |
split [-gLlnP]
[-o
property=value]…
[-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
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.
