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]a| [-R root] pool newpool
	   [device]a|

DESCRIPTION
     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 de-
     vice in each mirror is split from pool to create newpool.

     The optional device specification causes the specified device(s) to be  in-
     cluded 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/of-
	     fline/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.  With-
	     out 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.
