Create a pool with 3 vdevs. 27# 2. Start trimming vdevs 1 and 2 with one invocation of 'zpool trim -w' 28# 3. Start trimming vdev 3 with a second invocation of 'zpool trim -w' 29# 4. Cancel the trim of vdev 1. Check that neither waiting process exits. 30# 5. Cancel the trim of vdev 3. Check that only the second waiting process 31# exits. 32# 6. Cancel the trim of vdev 2. Check that the first waiting process exits. 33# 34 35function cleanup 36{ 37 kill_if_running $trim12_pid 38 kill_if_running $trim3_pid 39 poolexists $TESTPOOL && destroy_pool $TESTPOOL 40 [[ -d "$TESTDIR" ]] && log_must rm -r "$TESTDIR" 41} 42 43if is_freebsd; then 44 log_unsupported "FreeBSD has no hole punching mechanism for the time being." 45fi 46 47typeset trim12_pid trim3_pid 48typeset -r VDEV1="$TESTDIR/file_vdev1" 49typeset -r VDEV2="$TESTDIR/file_vdev2" 50typeset -r VDEV3="$TESTDIR/file_vdev3" 51 52log_onexit cleanup 53 54log_must mkdir "$TESTDIR" 55log_must truncate -s 10G "$VDEV1" "$VDEV2" "$VDEV3" 56log_must zpool create -f $TESTPOOL "$VDEV1" "$VDEV2" "$VDEV3" 57 58log_bkgrnd zpool trim -r 1M -w $TESTPOOL "$VDEV1" "$VDEV2" 59trim12_pid=$! 60log_bkgrnd zpool trim -r 1M -w $TESTPOOL "$VDEV3" 61trim3_pid=$! 62 63# Make sure that we are really waiting 64log_must sleep 3 65proc_must_exist $trim12_pid 66proc_must_exist $trim3_pid 67 68# 69# Cancel trim of one of disks started by trim12, make sure neither 70# process exits 71# 72log_must zpool trim -c $TESTPOOL "$VDEV1" 73proc_must_exist $trim12_pid 74proc_must_exist $trim3_pid 75 76# 77# Cancel trim started by trim3, make sure that process exits, but 78# trim12 doesn't 79# 80log_must zpool trim -c $TESTPOOL "$VDEV3" 81proc_must_exist $trim12_pid 82bkgrnd_proc_succeeded $trim3_pid 83 84# Cancel last trim started by trim12, make sure it returns. 85log_must zpool trim -c $TESTPOOL "$VDEV2" 86bkgrnd_proc_succeeded $trim12_pid 87 88log_pass "'zpool trim -w' works." 89
