Set 'compression' or 'compress' to on or lzjb 45# 2. Set different recordsize with ZFS filesystem 46# 3. Repeatedly using 'randfree_file' to create a file and then free its 47# storage space with different range, the system should work normally. 48# 49# TESTABILITY: explicit 50# 51# TEST_AUTOMATION_LEVEL: automated 52# 53# CODING_STATUS: COMPLETED (2006-07-26) 54# 55# __stc_assertion_end 56# 57################################################################################ 58 59verify_runnable "both" 60 61function cleanup 62{ 63 $RM -f $TESTDIR/* 64} 65 66function create_free_testing #<file size> <file> 67{ 68 typeset -i fsz=$1 69 typeset file=$2 70 typeset -i start=0 71 typeset -i len=0 72 typeset -i dist=0 73 74 for start in 0 `expr $RANDOM % $fsz` 75 do 76 (( dist = fsz - start )) 77 for len in `expr $RANDOM % $dist` $dist \ 78 `expr $start + $dist`; do 79 log_must $RANDFREE_FILE -l fsz -s $start \ 80 -n $len $file 81 [[ -e $file ]] && \ 82 log_must $RM -f $file 83 done 84 done 85} 86 87 88log_assert "Creating non-power-of-2 blocksize file and freeing the file \ 89 storage space at will should work normally with compression setting" 90log_onexit cleanup 91 92fs=$TESTPOOL/$TESTFS 93single_blk_file=$TESTDIR/singleblkfile.${TESTCASE_ID} 94multi_blk_file=$TESTDIR/multiblkfile.${TESTCASE_ID} 95typeset -i blksize=512 96typeset -i fsize=0 97typeset -i avail=0 98typeset -i blknum=0 99 100for propname in "compression" "compress" 101do 102 for value in $(get_compress_opts zfs_compress) 103 do 104 log_must $ZFS set compression=$value $fs 105 real_val=$(get_prop $propname $fs) 106 if [[ $value == "gzip-6" ]]; then 107 value="gzip" 108 fi 109 [[ $real_val != $value ]] && \ 110 log_fail "Set property $propname=$value failed." 111 112 (( blksize = 512 )) 113 while (( blksize <= 131072 )); do 114 log_must $ZFS set recordsize=$blksize $fs 115 116 # doing single block testing 117 (( fsize = $RANDOM )) 118 if (( fsize > blksize )); then 119 (( fsize = fsize % blksize )) 120 fi 121 if (( (fsize % 2) == 0 )); then 122 #make sure fsize is non-power-of-2 123 (( fsize = fsize + 1 )) 124 fi 125 create_free_testing $fsize $single_blk_file 126 127 # doing multiple blocks testing 128 avail=$(get_prop available $fs) 129 (( blknum = avail / blksize )) 130 # we just test <10 multi-blocks to limit testing time 131 (( blknum = blknum % 9 )) 132 while (( blknum < 2 )); do 133 (( blknum = blknum + $RANDOM % 9 )) 134 done 135 if (( (blknum % 2) == 0 )); then 136 (( blknum = blknum + 1 )) # keep blknum as odd 137 fi 138 (( fsize = blknum * blksize )) 139 create_free_testing $fsize $multi_blk_file 140 141 (( blksize = blksize * 2 )) 142 done 143 done 144done 145 146log_pass "Creating and freeing non-power-of-2 blocksize file work as expected." 147
