Set 'compression' or 'compress' to on or lzjb 41# 2. Set different recordsize with ZFS filesystem 42# 3. Repeatedly using 'randfree_file' to create a file and then free its 43# storage space with different range, the system should work normally. 44# 45 46verify_runnable "both" 47 48function cleanup 49{ 50 $RM -f $TESTDIR/* 51} 52 53function create_free_testing #<file size> <file> 54{ 55 typeset -i fsz=$1 56 typeset file=$2 57 typeset -i start=0 58 typeset -i len=0 59 typeset -i dist=0 60 61 for start in 0 `expr $RANDOM % $fsz` 62 do 63 (( dist = fsz - start )) 64 for len in `expr $RANDOM % $dist` $dist \ 65 `expr $start + $dist`; do 66 log_must $RANDFREE_FILE -l fsz -s $start \ 67 -n $len $file 68 [[ -e $file ]] && \ 69 log_must $RM -f $file 70 done 71 done 72} 73 74 75log_assert "Creating non-power-of-2 blocksize file and freeing the file \ 76 storage space at will should work normally with compression setting" 77log_onexit cleanup 78 79fs=$TESTPOOL/$TESTFS 80single_blk_file=$TESTDIR/singleblkfile.$$ 81multi_blk_file=$TESTDIR/multiblkfile.$$ 82typeset -i blksize=512 83typeset -i fsize=0 84typeset -i avail=0 85typeset -i blknum=0 86 87for propname in "compression" "compress" 88do 89 for value in $(get_compress_opts zfs_compress) 90 do 91 log_must $ZFS set compression=$value $fs 92 real_val=$(get_prop $propname $fs) 93 if [[ $value == "gzip-6" ]]; then 94 value="gzip" 95 fi 96 [[ $real_val != $value ]] && \ 97 log_fail "Set property $propname=$value failed." 98 99 (( blksize = 512 )) 100 while (( blksize <= 131072 )); do 101 log_must $ZFS set recordsize=$blksize $fs 102 103 # doing single block testing 104 (( fsize = $RANDOM )) 105 if (( fsize > blksize )); then 106 (( fsize = fsize % blksize )) 107 fi 108 if (( (fsize % 2) == 0 )); then 109 #make sure fsize is non-power-of-2 110 (( fsize = fsize + 1 )) 111 fi 112 create_free_testing $fsize $single_blk_file 113 114 # doing multiple blocks testing 115 avail=$(get_prop available $fs) 116 (( blknum = avail / blksize )) 117 # we just test <10 multi-blocks to limit testing time 118 (( blknum = blknum % 9 )) 119 while (( blknum < 2 )); do 120 (( blknum = blknum + $RANDOM % 9 )) 121 done 122 if (( (blknum % 2) == 0 )); then 123 (( blknum = blknum + 1 )) # keep blknum as odd 124 fi 125 (( fsize = blknum * blksize )) 126 create_free_testing $fsize $multi_blk_file 127 128 (( blksize = blksize * 2 )) 129 done 130 done 131done 132 133log_pass "Creating and freeing non-power-of-2 blocksize file work as expected." 134
