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

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

SYNOPSIS
       zpool  split  [-gLlnP]  [-o  property=value]  [-R  root]	 pool  newpool
	     [device]

DESCRIPTION
       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 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 re-
	       gardless	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-
	       ties.

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