Create assigned number of files in ZFS filesystem as vdevs and use the first 37# file to create a pool 38# 2. Add other vdevs to the pool should get success 39# 3 Fill in the filesystem and create a partially written file 40# as vdev 41# 4. Add the new file into the pool should be failed. 42# 43 44verify_runnable "global" 45 46function cleanup 47{ 48 poolexists $TESTPOOL1 && \ 49 destroy_pool $TESTPOOL1 50 51 datasetexists $TESTPOOL/$TESTFS && \ 52 log_must $ZFS destroy -f $TESTPOOL/$TESTFS 53 poolexists $TESTPOOL && \ 54 destroy_pool $TESTPOOL 55 56 if [[ -d $TESTDIR ]]; then 57 log_must $RM -rf $TESTDIR 58 fi 59 60 partition_cleanup 61} 62 63 64# 65# Create a pool and fs on the assigned disk, and dynamically create large 66# numbers of files as vdevs.(the default value is <VDEVS_NUM>) 67# the first file will be used to create a pool for other vdevs to be added into 68# 69 70function setup_vdevs #<disk> 71{ 72 typeset disk=$1 73 typeset -l count=0 74 typeset -l largest_num=0 75 typeset -l slicesize=0 76 typeset vdev="" 77 78 79 # 80 # Get disk size for zfs filesystem 81 # 82 create_pool foo $disk 83 log_must $ZFS create foo/fs 84 typeset -l fs_size=$(get_prop "available" foo/fs) 85 destroy_pool foo 86 87 #64m is the minmum size for pool 88 (( largest_num = fs_size / (1024 * 1024 * 64) )) 89 if (( largest_num < $VDEVS_NUM )); then 90 # minus $largest_num/40 to leave 2.5% space for metadata. 91 (( vdevs_num=largest_num - largest_num/40 )) 92 file_size=64 93 vdev=$disk 94 else 95 vdevs_num=$VDEVS_NUM 96 file_size=$((fs_size / (1024 * 1024 * \ 97 (vdevs_num + vdevs_num / 40)))) 98 if (( file_size > FILE_SIZE )); then 99 file_size=$FILE_SIZE 100 fi 101 # plus $vdevs_num/40 to provide enough space for metadata. 102 (( slice_size = file_size * (vdevs_num + vdevs_num/40) )) 103 set_partition 0 "" ${slice_size}m $disk 104 vdev=${disk}s0 105 fi 106 107 create_pool $TESTPOOL $vdev 108 [[ -d $TESTDIR ]] && \ 109 log_must $RM -rf $TESTDIR 110 log_must $MKDIR -p $TESTDIR 111 log_must $ZFS create $TESTPOOL/$TESTFS 112 log_must $ZFS set mountpoint=$TESTDIR $TESTPOOL/$TESTFS 113 114 # Create a pool first using the first file, and make subsequent files 115 # ready as vdevs to add to the pool 116 117 log_must $MKFILE ${file_size}m ${TESTDIR}/file.$count 118 create_pool "$TESTPOOL1" "${TESTDIR}/file.$count" 119 log_must poolexists "$TESTPOOL1" 120 121 while (( count < vdevs_num )); do # minus 1 to avoid space non-enough 122 (( count = count + 1 )) 123 log_must $MKFILE ${file_size}m ${TESTDIR}/file.$count 124 vdevs_list="$vdevs_list ${TESTDIR}/file.$count" 125 done 126} 127 128log_assert " 'zpool add [-f]' can add large numbers of vdevs to the specified" \ 129 " pool without any errors." 130log_onexit cleanup 131 132if [[ $DISK_ARRAY_NUM == 0 ]]; then 133 disk=$DISK 134else 135 disk=$DISK0 136fi 137 138vdevs_list="" 139vdevs_num=$VDEVS_NUM 140file_size=$FILE_SIZE 141 142setup_vdevs $disk 143log_must $ZPOOL add -f "$TESTPOOL1" $vdevs_list 144log_must iscontained "$TESTPOOL1" "$vdevs_list" 145 146(( file_size = file_size * (vdevs_num/40 + 1 ) )) 147log_mustnot $MKFILE ${file_size}m ${TESTDIR}/broken_file 148 149log_mustnot $ZPOOL add -f "$TESTPOOL1" ${TESTDIR}/broken_file 150log_mustnot iscontained "$TESTPOOL1" "${TESTDIR}/broken_file" 151 152log_pass "'zpool successfully add [-f]' can add large numbers of vdevs to the" \ 153 "specified pool without any errors." 154
