Question

我调整了qcow2图像的大小以增加它的大小，在此过程中我通过了错误的设备进行扩展，现在virt-filesystems显示：

[root@node3 35]# virt-filesystems --long --parts --blkdevs -h -a disk.0
Name       Type       MBR  Size  Parent
/dev/sda1  partition  83   243M  /dev/sda
/dev/sda2  partition  05   1.0K  /dev/sda
/dev/sda5  partition  8e   9.8G  /dev/sda
/dev/sda   device     -    40G   -

我想调整/ dev / sda5以从/ dev / sda中获取所有40G，但是在虚拟机fdisk中，lv工具，parted不显示该空间而且我有点迷失。

感谢任何帮助或指导。

Fdisk输出：

Answer 1

我最后创建了一个新分区/ dev / vda6，我将其添加到LVM组。

在不关闭VM的情况下调整lvm分区的大小
