自动服务器安装Config文件--如何自动安装配置“填充磁盘”

Question

我试图创建云配置文件“填充磁盘”(lvm)，有人可以检查并告诉我是什么问题吗？(在ubuntu20.4服务器故障上获取根卷错误)

首先通过重新安排存储配置条目来创建交换逻辑卷。

您将创建一个将使用所有空间的根逻辑卷。

    - name: lv-root
      volgroup: lvm_volgroup-0
      size: -1
      wipe: superblock
      preserve: false
      type: lvm_partition
      id: lvm_partition-0

然后创建交换逻辑卷。

    - name: lv-swap
      volgroup: lvm_volgroup-0
      size: 4290772992B
      wipe: superblock
      preserve: false
      type: lvm_partition
      id: lvm_partition-1

安装程序不喜欢这样。我得到了这个错误日志(使用22.04安装程序)。

LVM_LogicalVolume(name='lv-root', volgroup=lvm_volgroup-0, size=-1, wipe='superblock', type='lvm_partition', id='lvm_partition-0') has negative size but is not final partition of LVM_VolGroup(name='vg0', devices=[partition-1], type='lvm_volgroup', id='lvm_volgroup-0')
