Growing the pool by adding a disk 39# increases the amount of space. 40# 41# STRATEGY: 42# 1) Fill a ZFS filesystem mirror/raidz until ENOSPC by creating lots 43# of files 44# 2) Grow the mirror/raidz by adding a disk 45# 3) Verify that more data can now be written to the file system 46# 47 48verify_runnable "global" 49 50log_assert "A zpool mirror/raidz may be increased in capacity by adding a disk." 51 52log_must $ZFS set compression=off $TESTPOOL/$TESTFS 53$FILE_WRITE -o create -f $TESTDIR/$TESTFILE1 \ 54 -b $BLOCK_SIZE -c $WRITE_COUNT -d 0 55 56typeset -i zret=$? 57readonly ENOSPC=28 58if [[ $zret -ne $ENOSPC ]]; then 59 log_fail "file_write completed w/o ENOSPC, aborting!!!" 60fi 61 62if [[ ! -s $TESTDIR/$TESTFILE1 ]]; then 63 log_fail "$TESTDIR/$TESTFILE1 was not created" 64fi 65 66# 67# $DISK will be set if we're using slices on one disk 68# 69if [[ -n $DISK ]]; then 70 log_must $ZPOOL add $TESTPOOL $POOLTYPE $DISK"s"$SLICE3 \ 71 $DISK"s"$SLICE4 72else 73 [[ -z $DISK2 || -z $DISK3 ]] && \ 74 log_unsupported "No spare disks available." 75 log_must $ZPOOL add -f $TESTPOOL $POOLTYPE $DISK2"s"$SLICE \ 76 $DISK3"s"$SLICE 77fi 78 79log_must $FILE_WRITE -o append -f $TESTDIR/$TESTFILE1 \ 80 -b $BLOCK_SIZE -c $SMALL_WRITE_COUNT -d 0 81 82log_must $ZFS inherit compression $TESTPOOL/$TESTFS 83log_pass "TESTPOOL mirror/raidz successfully grown" 84
