Create a pool on sparse file vdevs to trim. 32# 2. Generate some interesting pool data which can be trimmed. 33# 3. Manually trim the pool. 34# 4. Verify trim IOs of the expected type were issued for the pool. 35# 5. Verify data integrity of the pool after trim. 36# 6. Repeat test for striped, mirrored, and RAIDZ pools. 37 38verify_runnable "global" 39 40log_assert "Run 'zpool trim' and verify pool data integrity" 41 42function cleanup 43{ 44 if poolexists $TESTPOOL; then 45 destroy_pool $TESTPOOL 46 fi 47 48 log_must rm -f $TRIM_VDEVS 49 50 log_must set_tunable64 TRIM_EXTENT_BYTES_MIN $trim_extent_bytes_min 51 log_must set_tunable64 TRIM_TXG_BATCH $trim_txg_batch 52} 53log_onexit cleanup 54 55# Minimum trim size is decreased to verify all trim sizes. 56typeset trim_extent_bytes_min=$(get_tunable TRIM_EXTENT_BYTES_MIN) 57log_must set_tunable64 TRIM_EXTENT_BYTES_MIN 4096 58 59# Reduced TRIM_TXG_BATCH to make trimming more frequent. 60typeset trim_txg_batch=$(get_tunable TRIM_TXG_BATCH) 61log_must set_tunable64 TRIM_TXG_BATCH 8 62 63for type in "" "mirror" "raidz" "draid"; do 64 log_must truncate -s 1G $TRIM_VDEVS 65 66 log_must zpool create -f $TESTPOOL $type $TRIM_VDEVS 67 68 # Add and remove data from the pool in a random fashion in order 69 # to generate a variety of interesting ranges to be manually trimmed. 70 for n in {0..10}; do 71 dir="/$TESTPOOL/trim-$((RANDOM % 5))" 72 filesize=$((4096 + ((RANDOM * 691) % 131072) )) 73 log_must rm -rf $dir 74 log_must fill_fs $dir 10 10 $filesize 1 R 75 zpool sync 76 done 77 log_must du -hs /$TESTPOOL 78 79 log_must timeout 120 zpool trim -w $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 "Manual trim successfully validated" 89
