我嘗試按照以下說明進行操作： 無法使用 resize2fs 調整分割區大小
但似乎沒有任何作用。
的輸出lsblk是：
[AWS root@archive ~]$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 300G 0 disk
├─xvda1 202:1 0 500M 0 part /boot
├─xvda2 202:2 0 29.5G 0 part
│ ├─vg_archive-lv_root (dm-0) 253:0 0 147.6G 0 lvm /
│ └─vg_archive-lv_swap (dm-1) 253:1 0 2G 0 lvm [SWAP]
├─xvda3 202:3 0 10G 0 part
│ └─vg_archive-lv_root (dm-0) 253:0 0 147.6G 0 lvm /
└─xvda4 202:4 0 110G 0 part
└─vg_archive-lv_root (dm-0) 253:0 0 147.6G 0 lvm /
您可以看到 300Gb 可用，但我無法將根卷從 150Gb 擴展。非常感謝任何幫助，謝謝。
更新：我想添加linux發行版，它很舊，這可能是問題的一部分...

根據評論中的要求，這是上面連結中建議命令的輸出：

我透過執行以下操作成功調整了磁碟大小：
將 AWS 控制台中的映像大小從 150Gb 增加到 300Gb 後，我執行了以下命令：
[AWS root@archive ~]$ pvresize /dev/xvda4
Physical volume "/dev/xvda4" changed
1 physical volume(s) resized / 0 physical volume(s) not resized
重啟
[AWS root@archive ~]$ growpart /dev/xvda 4

[AWS root@archive ~]$ pvresize /dev/xvda4

[AWS root@archive ~]$ lvextend /dev/vg_archive/lv_root -l+100%FREE

再次重新啟動，因為它不起作用
[AWS root@archive ~]$ lvextend /dev/vg_archive/lv_root -l+100%FREE

Performing an on-line resize of /dev/vg_archive/lv_root to 78004224 (4k) blocks.
The filesystem on /dev/vg_archive/lv_root is now 78004224 blocks long.
[AWS root@archive ~]$ df -h
Filesystem Size Used Avail Use% Mounted on

所以我不完全確定哪個命令需要重新啟動，但我必須重新啟動才能成功調整大小。
我希望這對其他人有幫助
