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 poolexists $TESTPOOL && \ 70 destroy_pool $TESTPOOL 71 72 if [[ -d $TESTDIR ]]; then 73 log_must $RM -rf $TESTDIR 74 fi 75} 76 77 78# 79# Create a pool and fs on the assigned disk, and dynamically create large 80# numbers of files as vdevs.(the default value is <VDEVS_NUM>) 81# the first file will be used to create a pool for other vdevs to be added into 82# 83 84function setup_vdevs #<disk> 85{ 86 typeset disk=$1 87 typeset -i count=0 88 typeset -i largest_num=0 89 typeset -i slicesize=0 90 typeset vdev="" 91 92 fs_size=$(get_available_disk_size $disk) 93 94 # 64M is the minimum size for the pool 95 (( largest_num = fs_size / (1024 * 1024 * 64) )) 96 if (( largest_num < $VDEVS_NUM )); then 97 # Minus $largest_num/20 to leave 5% space for metadata. 98 (( vdevs_num=largest_num - largest_num/20 )) 99 file_size=64 100 else 101 vdevs_num=$VDEVS_NUM 102 (( file_size = fs_size / (1024 * 1024 * (vdevs_num + vdevs_num/20)) )) 103 if (( file_size > FILE_SIZE )); then 104 file_size=$FILE_SIZE 105 fi 106 # Plus $vdevs_num/20 to provide enough space for metadata. 107 (( slice_size = file_size * (vdevs_num + vdevs_num/20) )) 108 wipe_partition_table $disk 109 set_partition 0 "" ${slice_size}m $disk 110 fi 111 vdev=${disk} 112 113 create_pool $TESTPOOL $vdev 114 [[ -d $TESTDIR ]] && \ 115 log_must $RM -rf $TESTDIR 116 log_must $MKDIR -p $TESTDIR 117 log_must $ZFS create $TESTPOOL/$TESTFS 118 log_must $ZFS set mountpoint=$TESTDIR $TESTPOOL/$TESTFS 119 120# Create a pool first using the first file, and make subsequent files ready 121# as vdevs to add to the pool 122 123 vdev=${TESTDIR}/file.$count 124 VDEV_SIZE=${file_size}m 125 log_must create_vdevs ${TESTDIR}/file.$count 126 create_pool "$TESTPOOL1" "${TESTDIR}/file.$count" 127 log_must poolexists "$TESTPOOL1" 128 129 while (( count < vdevs_num )); do # minus 1 to avoid space non-enough 130 (( count = count + 1 )) 131 log_must create_vdevs ${TESTDIR}/file.$count 132 vdevs_list="$vdevs_list ${TESTDIR}/file.$count" 133 done 134 unset VDEV_SIZE 135} 136 137log_assert " 'zpool add [-f]' can add large numbers of vdevs to the specified" \ 138 " pool without any errors." 139log_onexit cleanup 140 141vdevs_list="" 142vdevs_num=$VDEVS_NUM 143file_size=$FILE_SIZE 144 145setup_vdevs $DISK0 146log_must $ZPOOL add -f "$TESTPOOL1" $vdevs_list 147log_must iscontained "$TESTPOOL1" "$vdevs_list" 148 149log_pass "'zpool successfully add [-f]' can add large numbers of vdevs to the" \ 150 "specified pool without any errors." 151
