37# DESCRIPTION:
38# 	Replacing disks during I/O should pass for supported pools.
39#
40# STRATEGY:
41#	1. Create multidisk pools (stripe/mirror/draid) and
42#	   start some random I/O
43#	2. Replace a disk in the pool with another disk.
44#	3. Verify the integrity of the file system and the rebuilding.
45#
46# NOTE: Raidz does not support the sequential resilver (-s) option.
