31# DESCRIPTION:
32#	Verify 'zpool clear' doesn't cause concurrent resilvers
33#
34# STRATEGY:
35#	1. Create N(10) virtual disk files.
36#	2. Create draid pool based on the virtual disk files.
37#	3. Fill the filesystem with directories and files.
38#	4. Force-fault 2 vdevs and verify distributed spare is kicked in.
39#	5. Free the distributed spare by replacing the faulty drive.
40#	6. Run zpool clear and verify that it does not initiate 2 resilvers
41#	   concurrently while distributed spare gets kicked in.
