Create a pool on sparse file vdevs to trim. 33# 2. Set autotrim=on to enable asynchronous pool trimming. 34# 3. Generate some interesting pool data which can be trimmed. 35# 4. Verify trim IOs of the expected type were issued for the pool. 36# 5. Verify data integrity of the pool after trim. 37# 6. Repeat test for striped, mirrored, and RAIDZ pools. 38 39verify_runnable "global" 40 41log_assert "Set 'autotrim=on' pool property verify pool data integrity" 42 43function cleanup 44{ 45 if poolexists $TESTPOOL; then 46 destroy_pool $TESTPOOL 47 fi 48 49 log_must rm -f $TRIM_VDEVS 50 51 log_must set_tunable32 zfs_trim_extent_bytes_min $trim_extent_bytes_min 52 log_must set_tunable32 zfs_trim_txg_batch $trim_txg_batch 53} 54log_onexit cleanup 55 56# Minimum trim size is decreased to verify all trim sizes. 57typeset trim_extent_bytes_min=$(get_tunable zfs_trim_extent_bytes_min) 58log_must set_tunable32 zfs_trim_extent_bytes_min 4096 59 60# Reduced zfs_trim_txg_batch to make trimming more frequent. 61typeset trim_txg_batch=$(get_tunable zfs_trim_txg_batch) 62log_must set_tunable32 zfs_trim_txg_batch 8 63 64for type in "" "mirror" "raidz" "raidz2" "raidz3"; do 65 log_must truncate -s 1G $TRIM_VDEVS 66 67 log_must zpool create -f $TESTPOOL $type $TRIM_VDEVS 68 log_must zpool set autotrim=on $TESTPOOL 69 70 # Add and remove data from the pool in a random fashion in order 71 # to generate a variety of interesting ranges to be auto trimmed. 72 for n in {0..10}; do 73 dir="/$TESTPOOL/autotrim-$((RANDOM % 5))" 74 filesize=$((4096 + ((RANDOM * 691) % 131072) )) 75 log_must rm -rf $dir 76 log_must fill_fs $dir 10 10 $filesize 1 R 77 zpool sync 78 done 79 log_must du -hs /$TESTPOOL 80 81 verify_trim_io $TESTPOOL "ind" 10 82 verify_pool $TESTPOOL 83 84 log_must zpool destroy $TESTPOOL 85 log_must rm -f $TRIM_VDEVS 86done 87 88log_pass "Automatic trim successfully validated" 89
