Growing the pool by adding a disk 39# increases the amount of space. 40# 41# STRATEGY: 42# 1. Fill the filesystem on mirror/raidz pool by writing a file until ENOSPC. 43# 2. Grow the mirror/raidz pool by adding another mirror/raidz vdev. 44# 3. Verify that more data can now be written to the filesystem. 45 46verify_runnable "global" 47 48function cleanup 49{ 50 destroy_pool $TESTPOOL 51 rm -f $DEVICE1 $DEVICE2 $DEVICE3 $DEVICE4 52} 53 54log_assert "mirror/raidz pool may be increased in capacity by adding a disk" 55 56log_onexit cleanup 57 58readonly ENOSPC=28 59 60for pooltype in "mirror" "raidz"; do 61 log_note "Creating pool type: $pooltype" 62 63 truncate -s $SPA_MINDEVSIZE $DEVICE1 $DEVICE2 64 create_pool $TESTPOOL $pooltype $DEVICE1 $DEVICE2 65 66 log_must zfs create $TESTPOOL/$TESTFS 67 log_must zfs set mountpoint=$TESTDIR $TESTPOOL/$TESTFS 68 log_must zfs set compression=off $TESTPOOL/$TESTFS 69 70 file_write -o create -f $TESTDIR/$TESTFILE1 \ 71 -b $BLOCK_SIZE -c $WRITE_COUNT -d 0 72 73 [[ $? -ne $ENOSPC ]] && \ 74 log_fail "file_write completed w/o ENOSPC" 75 76 [[ ! -s $TESTDIR/$TESTFILE1 ]] && \ 77 log_fail "$TESTDIR/$TESTFILE1 was not created" 78 79 truncate -s $SPA_MINDEVSIZE $DEVICE3 $DEVICE4 80 log_must zpool add $TESTPOOL $pooltype $DEVICE3 $DEVICE4 81 82 log_must file_write -o append -f $TESTDIR/$TESTFILE1 \ 83 -b $BLOCK_SIZE -c $SMALL_WRITE_COUNT -d 0 84 85 log_must destroy_pool $TESTPOOL 86 rm -f $DEVICE1 $DEVICE2 $DEVICE3 $DEVICE4 87done 88 89log_pass "mirror/raidz pool successfully grown" 90
