# DESCRIPTION:
#	Resilver prevent scrub from starting until the resilver completes
#
# STRATEGY:
#	1. Setup a mirror pool and filled with data.
#	2. Detach one of devices
#	3. Verify scrub failed until the resilver completed
#
# NOTES:
#	Artificially limit the scrub speed by setting the zfs_scan_vdev_limit
#	low in order to ensure that the scrub does not complete early.
