ec2卷装载错误

在尝试安装ec2卷时遇到以下错误

[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)' 

另外，试图安装下面的部分

 [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.
