Create a one-disk pool. 31# 2. Write data to the pool. 32# 3. Start trimming and verify that trimming is active. 33# 4. Write more data to the pool. 34# 5. Export the pool and use zdb to validate checksums. 35# 36 37function cleanup 38{ 39 if poolexists $TESTPOOL; then 40 destroy_pool $TESTPOOL 41 fi 42 43 if [[ -d "$TESTDIR" ]]; then 44 rm -rf "$TESTDIR" 45 fi 46} 47log_onexit cleanup 48 49LARGESIZE=$((MINVDEVSIZE * 4)) 50LARGEFILE="$TESTDIR/largefile" 51 52log_must mkdir "$TESTDIR" 53log_must truncate -s $LARGESIZE "$LARGEFILE" 54log_must zpool create $TESTPOOL "$LARGEFILE" 55 56log_must dd if=/dev/urandom of=/$TESTPOOL/file1 bs=1048576 count=64 57sync_all_pools 58log_must zpool trim $TESTPOOL 59 60[[ -z "$(trim_progress $TESTPOOL $DISK1)" ]] && \ 61 log_fail "Trimming did not start" 62 63log_must dd if=/dev/urandom of=/$TESTPOOL/file2 bs=1048576 count=64 64sync_all_pools 65 66log_must zpool export $TESTPOOL 67log_must zdb -e -p "$TESTDIR" -cc $TESTPOOL 68 69log_pass "Trimming does not corrupt existing or new data" 70
