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.
