我要求将虚拟服务器的磁盘大小从 20 GB 扩展到 80 GB。
此后，磁盘大小/dev/sda增加到 80 GiB。但大小/dev/sda2保持不变，为 19.5 GiB：
root@localhost:/home/worker# fdisk -l
Disk /dev/sda: 80 GiB, 85899345920 bytes, 167772160 sectors
Disk model: Virtual disk
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

Disk identifier: 0x520f1760

Disk /dev/mapper/vg00-lv01: 17.63 GiB, 18912116736 bytes, 36937728 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
我可以使用以下命令修复此问题growpart：
root@localhost:# growpart /dev/sda 2

/dev/sda2 999424 167772126 166772703 79.5G 8e Linux LVM
但是我的文件系统仍然没有足够的空间。
root@localhost:# df -h

udev 947M 0 947M 0% /dev

从谷歌上我了解到我还必须以某种方式增加分区。但是在网上我只找到了关于如何在“ext4”或其他类型上执行此操作的信息。在我的例子中，类型指定为LVM2_member。我不知道如何处理。
root@localhost:# blkid
/dev/mapper/vg00-lv00: UUID="d236bafc-c18c-49aa-816d-85f0c7afc810" TYPE="swap"

/dev/sda1: UUID="de2cb53e-6086-4fd5-99a9-1c22674a4f91" TYPE="ext4" PARTUUID="520f1760-01"
/dev/sda2: UUID="R5VWXg-jamB-5dWM-PpwY-7a49-LRz7-Vrvdl2" TYPE="LVM2_member" PARTUUID="520f1760-02"
我试过lvextend没有效果：

New size (4509 extents) matches existing size (4509 extents).

联系支持人员后找到了解决方案。 https://www.ionos.de/hilfe/index.php?id=4315
基本上，申请之前的步骤pvresize /dev/sda2缺失了lvextend。
现已解决。
