ZPOOL-SPLIT(8)		FreeBSD	System Manager's Manual		ZPOOL-SPLIT(8)

     zpool-split -- split devices off ZFS storage pool,	creating new pool

     zpool split [-gLlnP] [-o property=value]a|	[-R root] pool newpool

     Splits devices off	pool creating newpool.	All vdevs in pool must be mir-
     rors 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 de-
	     tach/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 proper-

     -R	root
	     Set altroot for newpool to	root and automatically import it.
