Create a pool with 3 vdevs. 28# 2. Start trimming vdevs 1 and 2 with one invocation of 'zpool trim -w' 29# 3. Start trimming vdev 3 with a second invocation of 'zpool trim -w' 30# 4. Cancel the trim of vdev 1. Check that neither waiting process exits. 31# 5. Cancel the trim of vdev 3. Check that only the second waiting process 32# exits. 33# 6. Cancel the trim of vdev 2. Check that the first waiting process exits. 34# 35 36function cleanup 37{ 38 kill_if_running $trim12_pid 39 kill_if_running $trim3_pid 40 poolexists $TESTPOOL && destroy_pool $TESTPOOL 41 [[ -d "$TESTDIR" ]] && log_must rm -r "$TESTDIR" 42} 43 44if is_freebsd; then 45 log_unsupported "FreeBSD has no hole punching mechanism for the time being." 46fi 47 48typeset trim12_pid trim3_pid 49typeset -r VDEV1="$TESTDIR/file_vdev1" 50typeset -r VDEV2="$TESTDIR/file_vdev2" 51typeset -r VDEV3="$TESTDIR/file_vdev3" 52 53log_onexit cleanup 54 55log_must mkdir "$TESTDIR" 56log_must truncate -s 10G "$VDEV1" "$VDEV2" "$VDEV3" 57log_must zpool create -f $TESTPOOL "$VDEV1" "$VDEV2" "$VDEV3" 58 59log_bkgrnd zpool trim -r 1M -w $TESTPOOL "$VDEV1" "$VDEV2" 60trim12_pid=$! 61log_bkgrnd zpool trim -r 1M -w $TESTPOOL "$VDEV3" 62trim3_pid=$! 63 64# Make sure that we are really waiting 65log_must sleep 3 66proc_must_exist $trim12_pid 67proc_must_exist $trim3_pid 68 69# 70# Cancel trim of one of disks started by trim12, make sure neither 71# process exits 72# 73log_must zpool trim -c $TESTPOOL "$VDEV1" 74proc_must_exist $trim12_pid 75proc_must_exist $trim3_pid 76 77# 78# Cancel trim started by trim3, make sure that process exits, but 79# trim12 doesn't 80# 81log_must zpool trim -c $TESTPOOL "$VDEV3" 82proc_must_exist $trim12_pid 83bkgrnd_proc_succeeded $trim3_pid 84 85# Cancel last trim started by trim12, make sure it returns. 86log_must zpool trim -c $TESTPOOL "$VDEV2" 87bkgrnd_proc_succeeded $trim12_pid 88 89log_pass "'zpool trim -w' works." 90
