無法在 aws 實例上調整磁碟大小
我嘗試按照以下說明進行操作： Can’t resize a partition using resize2fs
但似乎沒有任何效果。
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，但我無法從 150Gb 擴展根卷。非常感謝任何幫助，謝謝。
更新：以為我會添加 linux 發行版，它很舊，可能是問題的一部分…

我通過執行以下操作成功調整了磁碟大小：
在將 AWS 控制台中的圖像大小從 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 CHANGED: partition=4 start=83875365 old: size=230693400 end=314568765 new: size=545262165,end=629137530 [AWS root@archive ~]$ pvresize /dev/xvda4 Physical volume "/dev/xvda4" changed 1 physical volume(s) resized / 0 physical volume(s) not resized [AWS root@archive ~]$ lvextend /dev/vg_archive/lv_root -l+100%FREE New size (37776 extents) matches existing size (37776 extents) Run `lvextend --help' for more information. [AWS root@archive ~]$ resize2fs /dev/vg_archive/lv_root resize2fs 1.41.12 (17-May-2010) The filesystem is already 38682624 blocks long. Nothing to do!重新啟動，因為它不起作用

我希望這對其他人有幫助
