|

|
|

.
|
|
.Sh DESCRIPTION
|
|
Splits devices off
|
|
.Ar pool
|
|
creating
|
|
.Ar newpool .
|
|
All vdevs in
|
|
.Ar pool
|
|
must be mirrors and the pool must not be in the process of resilvering.
|
|
At the time of the split,
|
|
.Ar newpool
|
|
will be a replica of
|
|
.Ar pool .
|
|
By default, the
|
|
last device in each mirror is split from
|
|
.Ar pool
|
|
to create
|
|
.Ar newpool .
|
|
.Pp
|
|
The optional device specification causes the specified device(s) to be
|
|
included in the new
|
|
.Ar pool
|
|
and, should any devices remain unspecified,
|
|
the last device in each mirror is used as would be by default.
|
|
.Bl -tag -width Ds
|
|
.It Fl 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.
|
|
.It Fl 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
|
|
.Pa /dev/disk/
|
|
path used to open it.
|
|
.It Fl 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
|
|
.Sy keylocation Ns = Ns Sy 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.
|
|
.It Fl n
|
|
Do a dry-run
|
|
.Pq Qq No-op
|
|
split: do not actually perform it.
|
|
Print out the expected configuration of
|
|
.Ar newpool .
|
|
.It Fl P
|
|
Display full paths for vdevs instead of only the last component of
|
|
the path.
|
|
This can be used in conjunction with the
|
|
.Fl L
|
|
flag.
|
|
.It Fl o Ar property Ns = Ns Ar value
|
|
Sets the specified property for
|
|
.Ar newpool .
|
|
See the
|
|
.Xr zpoolprops 7
|
|
manual page for more information on the available pool properties.
|
|
.It Fl R Ar root
|
|
Set
|
|
.Sy altroot
|
|
for
|
|
.Ar newpool
|
|
to
|
|
.Ar root
|
|
and automatically import it.
