Create a pool on sparse file vdevs to trim. # 2. Set autotrim=on to enable asynchronous pool trimming. # 3. Generate some interesting pool data which can be trimmed. # 4. Verify trim IOs of the expected type were issued for the pool. # 5. Verify data integrity of the pool after trim. # 6. Repeat test for striped, mirrored, and RAIDZ pools. verify_runnable "global" log_assert "Set 'autotrim=on' pool property verify pool data integrity" function cleanup { if poolexists $TESTPOOL; then destroy_pool $TESTPOOL fi log_must rm -f $TRIM_VDEVS log_must set_tunable64 TRIM_EXTENT_BYTES_MIN $trim_extent_bytes_min log_must set_tunable64 TRIM_TXG_BATCH $trim_txg_batch } log_onexit cleanup # Minimum trim size is decreased to verify all trim sizes. typeset trim_extent_bytes_min=$(get_tunable TRIM_EXTENT_BYTES_MIN) log_must set_tunable64 TRIM_EXTENT_BYTES_MIN 4096 # Reduced TRIM_TXG_BATCH to make trimming more frequent. typeset trim_txg_batch=$(get_tunable TRIM_TXG_BATCH) log_must set_tunable64 TRIM_TXG_BATCH 8 for type in "" "mirror" "raidz" "raidz2" "raidz3"; do log_must truncate -s 1G $TRIM_VDEVS log_must zpool create -f $TESTPOOL $type $TRIM_VDEVS log_must zpool set autotrim=on $TESTPOOL # Add and remove data from the pool in a random fashion in order # to generate a variety of interesting ranges to be auto trimmed. for n in {0..10}; do dir="/$TESTPOOL/autotrim-$((RANDOM % 5))" filesize=$((4096 + ((RANDOM * 691) % 131072) )) log_must rm -rf $dir log_must fill_fs $dir 10 10 $filesize 1 R zpool sync done log_must du -hs /$TESTPOOL verify_trim_io $TESTPOOL "ind" 10 verify_pool $TESTPOOL log_must zpool destroy $TESTPOOL log_must rm -f $TRIM_VDEVS done log_pass "Automatic trim successfully validated"
