Create a one-disk pool using a sparse file. 32# 2. Initialize the pool and verify the file vdev is no longer sparse. 33# 3. Trim the pool and verify the file vdev is again sparse. 34# 35 36function cleanup 37{ 38 if poolexists $TESTPOOL; then 39 destroy_pool $TESTPOOL 40 fi 41 42 if [[ -d "$TESTDIR" ]]; then 43 rm -rf "$TESTDIR" 44 fi 45 46 log_must set_tunable64 TRIM_EXTENT_BYTES_MIN $trim_extent_bytes_min 47} 48log_onexit cleanup 49 50LARGESIZE=$((MINVDEVSIZE * 4)) 51LARGEFILE="$TESTDIR/largefile" 52 53# Reduce trim size to allow for tighter tolerance below when checking. 54typeset trim_extent_bytes_min=$(get_tunable TRIM_EXTENT_BYTES_MIN) 55log_must set_tunable64 TRIM_EXTENT_BYTES_MIN 4096 56 57log_must mkdir "$TESTDIR" 58log_must truncate -s $LARGESIZE "$LARGEFILE" 59log_must zpool create $TESTPOOL "$LARGEFILE" 60 61original_size=$(du -B1 "$LARGEFILE" | cut -f1) 62 63log_must zpool initialize $TESTPOOL 64 65while [[ "$(initialize_progress $TESTPOOL $LARGEFILE)" -lt "100" ]]; do 66 sleep 0.5 67done 68 69new_size=$(du -B1 "$LARGEFILE" | cut -f1) 70log_must within_tolerance $new_size $LARGESIZE $((128 * 1024 * 1024)) 71 72log_must zpool trim $TESTPOOL 73 74while [[ "$(trim_progress $TESTPOOL $LARGEFILE)" -lt "100" ]]; do 75 sleep 0.5 76done 77 78new_size=$(du -B1 "$LARGEFILE" | cut -f1) 79log_must within_tolerance $new_size $original_size $((128 * 1024 * 1024)) 80 81log_pass "Trimmed appropriate amount of disk space" 82
