Create a one-disk pool. 31# 2. Start trimming and verify that trimming is active. 32# 3. Wait 3 seconds, then suspend trimming and verify that the progress 33# reporting says so. 34# 4. Wait 3 seconds and ensure trimming progress doesn't advance. 35# 5. Restart trimming and verify that the progress doesn't regress. 36# 37 38function cleanup 39{ 40 if poolexists $TESTPOOL; then 41 destroy_pool $TESTPOOL 42 fi 43 44 if [[ -d "$TESTDIR" ]]; then 45 rm -rf "$TESTDIR" 46 fi 47} 48 49LARGEFILE="$TESTDIR/largefile" 50 51log_must mkdir "$TESTDIR" 52log_must truncate -s 10G "$LARGEFILE" 53log_must zpool create -f $TESTPOOL $LARGEFILE 54 55log_must zpool trim -r 256M $TESTPOOL 56sleep 2 57 58[[ -z "$(trim_progress $TESTPOOL $LARGEFILE)" ]] && \ 59 log_fail "Trimming did not start" 60 61sleep 3 62log_must zpool trim -s $TESTPOOL 63log_must eval "trim_prog_line $TESTPOOL $LARGEFILE | grep suspended" 64progress="$(trim_progress $TESTPOOL $LARGEFILE)" 65 66sleep 3 67[[ "$progress" -eq "$(trim_progress $TESTPOOL $LARGEFILE)" ]] || \ 68 log_fail "Trimming progress advanced while suspended" 69 70log_must zpool trim $TESTPOOL $LARGEFILE 71[[ "$progress" -le "$(trim_progress $TESTPOOL $LARGEFILE)" ]] || 72 log_fail "Trimming progress regressed after resuming" 73 74log_pass "Suspend + resume trimming works as expected" 75
