21# DESCRIPTION:
22# 'zpool wait' works when a scrub is paused or canceled.
23#
24# STRATEGY:
25# 1. Modify tunable so that scrubs won't complete while test is running.
26# 2. Start a scrub.
27# 3. Start a process that waits for the scrub.
28# 4. Wait a few seconds and then check that the wait process is actually
29#    waiting.
30# 5. Pause the scrub.
31# 6. Check that the wait process returns reasonably promptly.
32# 7. Repeat 2-6, except stop the scrub instead of pausing it.
