PVE 中的 win 主机为什么无法备份？

[Eaglemask]

不管 win 主机是开机还是关机状态都不行， 下面是 log ， 可能问题会在哪里？

遇到个很奇怪的问题， 见截图， 明明4T硬盘，还有最少3T的足够空间， 但是只显示 95.95 GiB， 这是个什么情况？

此外有个VM起不来， 提示：

TASK ERROR: NUMA needs to be enabled for memory hotplug

发现问题所在了 fdisk -l 看了下， 需要扩容了。


Disk /dev/mapper/pve-root: 96 GiB, 103079215104 bytes, 201326592 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

看错误是没空间了😳

Write error : No space left on device (cannot write compressed block)

没空了

分区分错了把。

安装 PVE 的时候默认用了 LVM 分区，只显示 95.95GiB 这个是 lvm_root ，应该还有 lvm_swap 和 lvm_data 之类的。另外，备份时空间不足是因为只能备份到 lvm_root 。解决方案是安装的时候就考虑到分区的大小或者你先试试调整 lvm 分区大小。我自己是有两块盘，所以没这个问题。

按照这个教程扩容 pve-root, 用了几年 pve 了，今天才发现竟然还有 pve-root 容量限制这么个回事。

@Eaglemask 明摆着是个 pve-root 是个 lvm 逻辑卷，好比普通分区，初始化肯定要指定一个分区大小，而并非什么容量限制！

你应该庆 pve 幸用了 lvm 逻辑卷，不然扩展容量会变得极为麻烦！
