# DESCRIPTION:
#   Replacing disks during I/O should pass for supported pools.
#
# STRATEGY:
#   1. Create multidisk pools (stripe/mirror/raidz) and
#      start some random I/O
#   2. Replace a disk in the pool with anbother disk.
#   3. Verify the integrity of the file system and the resilvering.
