Create a pool with two disks and some data. 26# 2. Modify a tunable to make sure removal doesn't make any progress. 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. Modify tunable to allow removal to complete. 31# 7. Monitor the waiting process to make sure it returns neither too soon nor 32# too late. 33# 8. Repeat 1-7, except using the '-w' flag for 'zpool remove' instead of using 34# 'zpool wait'. 35# 36 37function cleanup 38{ 39 kill_if_running $pid 40 log_must set_tunable32 REMOVAL_SUSPEND_PROGRESS 0 41 poolexists $TESTPOOL && destroy_pool $TESTPOOL 42} 43 44function do_test 45{ 46 typeset use_flag=$1 47 48 log_must zpool create -f $TESTPOOL $DISK1 $DISK2 49 log_must dd if=/dev/urandom of="/$TESTPOOL/testfile" bs=1k count=16k 50 51 # Start removal, but don't allow it to make any progress at first 52 log_must set_tunable32 REMOVAL_SUSPEND_PROGRESS 1 53 54 if $use_flag; then 55 log_bkgrnd zpool remove -w $TESTPOOL $DISK1 56 pid=$! 57 58 while ! is_pool_removing $TESTPOOL && proc_exists $pid; do 59 log_must sleep .5 60 done 61 else 62 log_must zpool remove $TESTPOOL $DISK1 63 log_bkgrnd zpool wait -t remove $TESTPOOL 64 pid=$! 65 fi 66 67 # Make sure the 'zpool wait' is actually waiting 68 log_must sleep 3 69 proc_must_exist $pid 70 71 # Unpause removal, and wait for it to finish 72 log_must set_tunable32 REMOVAL_SUSPEND_PROGRESS 0 73 check_while_waiting $pid "is_pool_removing $TESTPOOL" 74 75 log_must zpool destroy $TESTPOOL 76} 77 78log_onexit cleanup 79 80typeset pid 81 82do_test true 83do_test false 84 85log_pass "'zpool wait -t remove' and 'zpool remove -w' work." 86
