無法在 AWS 上掛載現有 EBS

我嘗試將現有的 EBS 儲存**（有數據）**安裝到一個實例，但它一直拋出這個錯誤。

mount: wrong fs type, bad option, bad superblock on /dev/xvdf,
      missing codepage or helper program, or other error

      In some cases useful info is found in syslog - try
      dmesg | tail or so.

儲存細節如下：

ec2-user@ip ~]$ sudo parted -l
Model: Xen Virtual Block Device (xvd)
Disk /dev/xvda: 8590MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Model: Xen Virtual Block Device (xvd)

dmesg | tail 顯示以下詳細資訊

看起來您已經對該塊設備進行了分區。在這種情況下，您需要安裝/dev/xvdf1，而不僅僅是/dev/xvdf。

對我來說，有一些神秘的文件導致了這個問題。

首先檢查您的分區以確保您正在執行 ext3 卷，然後：

對我來說，我必須使用以下命令清除目錄。

sudo mkfs -t ext3 /dev/sdf

警告：這可能會刪除您保存的文件。因此，您可以執行ls以確保不會失去重要的已保存文件
