Create assigned number of files in ZFS filesystem as vdevs and use the first 46# file to create a pool 47# 2. Add other vdevs to the pool should get success 48# 3 Fill in the filesystem and create a partially written file 49# as vdev 50# 4. Add the new file into the pool should be failed. 51# 52# TESTABILITY: explicit 53# 54# TEST_AUTOMATION_LEVEL: automated 55# 56# CODING_STATUS: COMPLETED (2005-10-09) 57# 58# __stc_assertion_end 59# 60################################################################################ 61 62verify_runnable "global" 63 64function cleanup 65{ 66 poolexists $TESTPOOL1 && \ 67 destroy_pool $TESTPOOL1 68 69 datasetexists $TESTPOOL/$TESTFS && \ 70 log_must $ZFS destroy -f $TESTPOOL/$TESTFS 71 poolexists $TESTPOOL && \ 72 destroy_pool $TESTPOOL 73 74 if [[ -d $TESTDIR ]]; then 75 log_must $RM -rf $TESTDIR 76 fi 77 78 partition_cleanup 79} 80 81 82# 83# Create a pool and fs on the assigned disk, and dynamically create large 84# numbers of files as vdevs.(the default value is <VDEVS_NUM>) 85# the first file will be used to create a pool for other vdevs to be added into 86# 87 88function setup_vdevs #<disk> 89{ 90 typeset disk=$1 91 typeset -i count=0 92 typeset -i largest_num=0 93 typeset -i slicesize=0 94 typeset vdev="" 95 96 fs_size=$(get_available_disk_size $disk) 97 98 # 64M is the minimum size for the pool 99 (( largest_num = fs_size / (1024 * 1024 * 64) )) 100 if (( largest_num < $VDEVS_NUM )); then 101 # Minus $largest_num/20 to leave 5% space for metadata. 102 (( vdevs_num=largest_num - largest_num/20 )) 103 file_size=64 104 vdev=$disk 105 else 106 vdevs_num=$VDEVS_NUM 107 (( file_size = fs_size / (1024 * 1024 * (vdevs_num + vdevs_num/20)) )) 108 if (( file_size > FILE_SIZE )); then 109 file_size=$FILE_SIZE 110 fi 111 # Plus $vdevs_num/20 to provide enough space for metadata. 112 (( slice_size = file_size * (vdevs_num + vdevs_num/20) )) 113 wipe_partition_table $disk 114 set_partition 0 "" ${slice_size}m $disk 115 vdev=${disk}p1 116 fi 117 118 create_pool $TESTPOOL $vdev 119 [[ -d $TESTDIR ]] && \ 120 log_must $RM -rf $TESTDIR 121 log_must $MKDIR -p $TESTDIR 122 log_must $ZFS create $TESTPOOL/$TESTFS 123 log_must $ZFS set mountpoint=$TESTDIR $TESTPOOL/$TESTFS 124 125# Create a pool first using the first file, and make subsequent files ready 126# as vdevs to add to the pool 127 128 vdev=${TESTDIR}/file.$count 129 VDEV_SIZE=${file_size}m 130 log_must create_vdevs ${TESTDIR}/file.$count 131 create_pool "$TESTPOOL1" "${TESTDIR}/file.$count" 132 log_must poolexists "$TESTPOOL1" 133 134 while (( count < vdevs_num )); do # minus 1 to avoid space non-enough 135 (( count = count + 1 )) 136 log_must create_vdevs ${TESTDIR}/file.$count 137 vdevs_list="$vdevs_list ${TESTDIR}/file.$count" 138 done 139 unset VDEV_SIZE 140} 141 142log_assert " 'zpool add [-f]' can add large numbers of vdevs to the specified" \ 143 " pool without any errors." 144log_onexit cleanup 145 146if [[ $DISK_ARRAY_NUM == 0 ]]; then 147 disk=$DISK 148else 149 disk=$DISK0 150fi 151 152vdevs_list="" 153vdevs_num=$VDEVS_NUM 154file_size=$FILE_SIZE 155 156setup_vdevs $disk 157log_must $ZPOOL add -f "$TESTPOOL1" $vdevs_list 158log_must iscontained "$TESTPOOL1" "$vdevs_list" 159 160log_pass "'zpool successfully add [-f]' can add large numbers of vdevs to the" \ 161 "specified pool without any errors." 162
