无法在 AWS 上挂载现有 EBS

Question

我尝试将现有的 EBS 存储（包含数据）安装到实例，但它不断抛出此错误。

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.

存储细节是：

ec2-user@ip ~]$ sudo parted -l

Answer 1

看起来您已经对该块设备进行了分区。在这种情况下，您需要安装/dev/xvdf1，而不仅仅是/dev/xvdf.
