Create a single-disk pool. 31# 2. Start trimming. 32# 3. Attach a second disk, ensure trimming continues. 33# 4. Detach the second disk, ensure trimming continues. 34# 5. Add a second disk, ensure trimming continues. 35# 6. Remove the first disk, ensure trimming stops. 36# 37 38DISK1="$(echo $DISKS | cut -d' ' -f1)" 39DISK2="$(echo $DISKS | cut -d' ' -f2)" 40 41log_must zpool create -f $TESTPOOL $DISK1 42 43log_must zpool trim -r 128M $TESTPOOL $DISK1 44progress="$(trim_progress $TESTPOOL $DISK1)" 45[[ -z "$progress" ]] && log_fail "Trim did not start" 46 47log_must zpool attach $TESTPOOL $DISK1 $DISK2 48new_progress="$(trim_progress $TESTPOOL $DISK1)" 49[[ "$progress" -le "$new_progress" ]] || \ 50 log_fail "Lost trimming progress on demotion to child vdev" 51progress="$new_progress" 52 53log_must zpool detach $TESTPOOL $DISK2 54new_progress="$(trim_progress $TESTPOOL $DISK1)" 55[[ "$progress" -le "$new_progress" ]] || \ 56 log_fail "Lost trimming progress on promotion to top vdev" 57progress="$new_progress" 58 59log_must zpool add $TESTPOOL $DISK2 60log_must zpool remove $TESTPOOL $DISK1 61[[ -z "$(trim_prog_line $TESTPOOL $DISK1)" ]] || \ 62 log_fail "Trimming continued after initiating removal" 63 64log_pass "Trimming worked as expected across attach/detach and add/remove" 65
