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. 32# 33 34function cleanup 35{ 36 kill_if_running $pid 37 log_must set_tunable32 REMOVAL_SUSPEND_PROGRESS 0 38 poolexists $TESTPOOL && destroy_pool $TESTPOOL 39} 40 41log_onexit cleanup 42 43typeset pid 44 45log_must zpool create -f $TESTPOOL $DISK1 $DISK2 46 47log_must dd if=/dev/urandom of="/$TESTPOOL/testfile" bs=1k count=16k 48 49# Start removal, but don't allow it to make any progress 50log_must set_tunable32 REMOVAL_SUSPEND_PROGRESS 1 51log_must zpool remove $TESTPOOL $DISK1 52 53log_bkgrnd zpool wait -t remove $TESTPOOL 54pid=$! 55 56log_must sleep 3 57proc_must_exist $pid 58 59log_must zpool remove -s $TESTPOOL 60bkgrnd_proc_succeeded $pid 61 62log_pass "'zpool wait -t remove' works when removal is canceled." 63
