21# DESCRIPTION:
22# 'zpool wait' works when device removal is canceled.
23#
24# STRATEGY:
25# 1. Create a pool with two disks and some data.
26# 2. Modify a tunable to make sure removal won't complete while test is running.
27# 3. Start removing one of the disks.
28# 4. Start 'zpool wait'.
29# 5. Sleep for a few seconds and check that the process is actually waiting.
30# 6. Cancel the removal of the device.
31# 7. Check that the wait process returns reasonably promptly.
