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