ec2 卷挂载错误

Question

尝试挂载 ec2 卷时出现以下错误

[ec2-user@ip-172-XX-XX-XX-XX ~]$ sudo mount /dev/xvdf /mnt
mount: /dev/xvdf is write-protected, mounting read-only
mount: unknown filesystem type '(null)'

此外，尝试安装零件如下

[ec2-user@ip-172-XX-XX-XX ~]$ sudo mount /dev/xvdf2 /mnt
    mount: wrong fs type, bad option, bad superblock on /dev/xvdf2,
       missing codepage or helper program, or other error

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

Answer 1

发布对我有用的解决方案，因为我没有在其他地方找到这个......

首先检查dmesg查看实际错误

dmesg | tail

并发现重复 UUID 的错误

[180875.598481] XFS (xvdf2): Filesystem has duplicate UUID 379de64d-ea11-4f5b-ae6a-0aa50ff7b24d - can't mount
[180970.058345] XFS (xvdf2): Filesystem has duplicate UUID 379de64d-ea11-4f5b-ae6a-0aa50ff7b24d - can't mount

所以要解决这个问题，请使用 nouuid 选项

[ec2-user@ip-172-XX-XX-XX ~]$ sudo mount -o nouuid /dev/xvdf2 /mnt
