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