fsck后出现问题，求救...

[weixin_38065391]

[root@WEB root]# fsck -A
fsck 1.26 (3-Feb-2002)
e2fsck 1.26 (3-Feb-2002)
/dev/sda5 is mounted.  

WARNING!!!  Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.

Do you really want to continue (y/n)? yes

/: recovering journal
fsck.ext3: Bad magic number in super-block while trying to re-open /
e2fsck: io manager magic bad!


结果现在无法再telnet登录到系统。

请问有什么办法恢复这个系统吗？
谢谢。
