我在 ubuntu 20.04 服务器操作系统上使用 maas 2.9 来安装 ubuntu 20.04 映像。
问题 1：如何利用剩余空间创建最后一个分区？
为了创建自定义存储配置，我添加了以下代码：
storage:
version: 1
config:
- id: sda
type: disk
wipe: superblock
ptable: gpt
model: VOLUME1 DISK
serial: 5000c500bbe76fab
grub_device: true
# Create a partition for boot
- id: sda1
type: partition
size: 3G
device: sda
name: boot-partition
wipe: superblock
- id: sda-boot
type: format
fstype: ext4
label: BOOT
# Get volume name from partition id
volume: sda1
#Mount this on boot
- id: sda1-mount
type: mount
path: /boot
#Get device name from format id
device: sda-boot
#Create partition for boot efi
- id: sda2
type: partition
size: 500M
device: sda
name: bootefi-partition
wipe: superblock
- id: sda-bootefi
type: format
fstype: fat32
label: BOOTEFI
volume: sda2
#Mount this on boot
- id: sda2-mount
type: mount
path: /boot/efi
device: sda-bootefi
#Create partition for usr
- id: sda3
type: partition
size: 20G
device: sda
name: usr-partition
wipe: superblock
- id: sda-usr
type: format
fstype: xfs
label: USR
volume: sda3
#Mount this on usr
- id: sda3-mount
type: mount
path: /usr
device: sda-usr
#Create partition for TMP
- id: sda4
type: partition
size: 5G
device: sda
name: tmp-partition
wipe: superblock
- id: sda-tmp
type: format
fstype: xfs
label: TMP
volume: sda4
#Mount this on tmp
- id: sda4-mount
type: mount
path: /tmp
device: sda-tmp
#Create partition for ROOT
- id: sda5
type: partition
size: 50G
device: sda
name: root-partition
wipe: superblock
flag: boot
- id: sda-root
type: format
fstype: xfs
label: ROOT
volume: sda5
#Mount this on /
- id: sda5-mount
type: mount
path: /
device: sda-root
#Create partition for HOME
- id: sda6
type: partition
size: 50G
device: sda
name: home-partition
wipe: superblock
- id: sda-home
type: format
fstype: xfs
label: HOME
volume: sda6
#Mount this on /home
- id: sda6-mount
type: mount
path: /home
device: sda-home
#Create partition for VAR
- id: sda7
type: partition
size: -1
device: sda
name: var-partition
wipe: superblock
#Format partition for var
- id: sda-var
type: format
fstype: xfs
label: VAR
volume: sda7
#Mount this on var
- id: sda7-mount
type: mount
path: /var
device: sda-var
我收到以下错误：

有人能告诉我应该为尺寸字段提供什么值吗？
问题 2：如果我将最后一个分区的大小定义为固定值，则操作系统安装成功。但在首次启动时，找不到 /root 分区
错误有点像下面这样：
/usr clean mount ok
/root/lib : mkdir failed
/sbin/ : not found
谢谢
