Create a one-disk pool using a sparse file. 33# 2. Initialize the pool and verify the file vdev is no longer sparse. 34# 3. Trim the pool and verify the file vdev is again sparse. 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 47 log_must set_tunable32 zfs_trim_extent_bytes_min $trim_extent_bytes_min 48} 49log_onexit cleanup 50 51LARGESIZE=$((MINVDEVSIZE * 4)) 52LARGEFILE="$TESTDIR/largefile" 53 54# Reduce trim size to allow for tighter tolerance below when checking. 55typeset trim_extent_bytes_min=$(get_tunable zfs_trim_extent_bytes_min) 56log_must set_tunable32 zfs_trim_extent_bytes_min 4096 57 58log_must mkdir "$TESTDIR" 59log_must truncate -s $LARGESIZE "$LARGEFILE" 60log_must zpool create $TESTPOOL "$LARGEFILE" 61 62original_size=$(du "$LARGEFILE" | cut -f1) 63original_size=$((original_size * 512)) 64 65log_must zpool initialize $TESTPOOL 66 67while [[ "$(initialize_progress $TESTPOOL $LARGEFILE)" -lt "100" ]]; do 68 sleep 0.5 69done 70 71new_size=$(du "$LARGEFILE" | cut -f1) 72new_size=$((new_size * 512)) 73log_must test $new_size -gt $((8 * 1024 * 1024)) 74 75log_must zpool trim $TESTPOOL 76 77while [[ "$(trim_progress $TESTPOOL $LARGEFILE)" -lt "100" ]]; do 78 sleep 0.5 79done 80 81new_size=$(du "$LARGEFILE" | cut -f1) 82new_size=$((new_size * 512)) 83log_must within_tolerance $new_size $original_size $((128 * 1024 * 1024)) 84 85log_pass "Trimmed appropriate amount of disk space" 86
