Set 'compression' or 'compress' to on or lzjb 40# 2. Set different recordsize with ZFS filesystem 41# 3. Repeatedly using 'randfree_file' to create a file and then free its 42# storage space with different range, the system should work normally. 43# 44 45verify_runnable "both" 46 47function cleanup 48{ 49 rm -f $TESTDIR/* 50} 51 52function create_free_testing #<file size> <file> 53{ 54 typeset -i fsz=$1 55 typeset file=$2 56 typeset -i start=0 57 typeset -i len=0 58 typeset -i dist=0 59 60 for start in 0 `expr $RANDOM % $fsz` 61 do 62 (( dist = fsz - start )) 63 for len in `expr $RANDOM % $dist` $dist \ 64 `expr $start + $dist`; do 65 66 # Zero length results in EINVAL for fallocate(2). 67 if is_linux; then 68 if (( len == 0 )); then 69 continue 70 fi 71 fi 72 73 log_must randfree_file -l fsz -s $start \ 74 -n $len $file 75 [[ -e $file ]] && \ 76 log_must rm -f $file 77 done 78 done 79} 80 81 82log_assert "Creating non-power-of-2 blocksize file and freeing the file \ 83 storage space at will should work normally with compression setting" 84log_onexit cleanup 85 86fs=$TESTPOOL/$TESTFS 87single_blk_file=$TESTDIR/singleblkfile.$$ 88multi_blk_file=$TESTDIR/multiblkfile.$$ 89typeset -i blksize=512 90typeset -i fsize=0 91typeset -i avail=0 92typeset -i blknum=0 93 94for propname in "compression" "compress" 95do 96 for value in "${compress_prop_vals[@]:1}" 97 do 98 log_must zfs set compression=$value $fs 99 real_val=$(get_prop $propname $fs) 100 if [[ $value == "gzip-6" ]]; then 101 value="gzip" 102 fi 103 [[ $real_val != $value ]] && \ 104 log_fail "Set property $propname=$value failed." 105 106 (( blksize = 512 )) 107 while (( blksize <= 131072 )); do 108 log_must zfs set recordsize=$blksize $fs 109 110 # doing single block testing 111 (( fsize = $RANDOM )) 112 if (( fsize > blksize )); then 113 (( fsize = fsize % blksize )) 114 fi 115 if (( (fsize % 2) == 0 )); then 116 #make sure fsize is non-power-of-2 117 (( fsize = fsize + 1 )) 118 fi 119 create_free_testing $fsize $single_blk_file 120 121 # doing multiple blocks testing 122 avail=$(get_prop available $fs) 123 (( blknum = avail / blksize )) 124 # we just test <10 multi-blocks to limit testing time 125 (( blknum = blknum % 9 )) 126 while (( blknum < 2 )); do 127 (( blknum = blknum + $RANDOM % 9 )) 128 done 129 if (( (blknum % 2) == 0 )); then 130 (( blknum = blknum + 1 )) # keep blknum as odd 131 fi 132 (( fsize = blknum * blksize )) 133 create_free_testing $fsize $multi_blk_file 134 135 (( blksize = blksize * 2 )) 136 done 137 done 138done 139 140log_pass "Creating and freeing non-power-of-2 blocksize file work as expected." 141
