21# DESCRIPTION:
22# Test zpool reopen -n while scrub is running.
23# Checks if re-plugged device is NOT resilvered.
24#
25# STRATEGY:
26# 1. Create a pool
27# 2. Remove a disk.
28# 3. Write test file to pool.
29# 4. Execute scrub.
30# 5. "Plug back" disk.
31# 6. Reopen a pool with an -n flag.
32# 7. Check if resilver was deferred.
33# 8. Check if trying to put device to offline fails because of no valid
34#    replicas.
35#
36# NOTES:
37#	A 125ms delay is added to make sure that the scrub is running while
38#	the reopen is invoked.
