Once we trigger the zpool scrub, all zpool/zfs command gets stuck for 180 seconds. Post 180 seconds zpool/zfs commands gets start executing however few more seconds(10s) it take to update the status. hence sleeping for 200 seconds so that we get the correct status.

# DESCRIPTION:
|
|
# Test /proc/spl/kstat/zfs/<pool>/state kstat
|
|
#
|
|
# STRATEGY:
|
|
# 1. Create a mirrored pool
|
|
# 2. Check that pool is ONLINE
|
|
# 3. Fault one disk
|
|
# 4. Check that pool is DEGRADED
|
|
# 5. Create a new pool with a single scsi_debug disk
|
|
# 6. Remove the disk
|
|
# 7. Check that pool is SUSPENDED
|
|
# 8. Add the disk back in
|
|
# 9. Clear errors and destroy the pools
