[求助] 自信调整硬盘分区容量，结果挂了，紧急求救

小悟空

很自信的按照论坛中扩容分区容量的方法对自己网站服务器进行了设置，结果重启后执行错误，无法挂载分区，可能有一步错误，怎么办，肿么办呀，紧急求救，没有备份呀，也没有在其他机器上做实验。。。。。。急死了呀。。。。。

QQ1655105会搞的大神帮忙啊，另外机器重新做了CentOS6，结果挂载一样的不行，看来是分区故障

没有备份恼火了啊。

admin

输入root密码,然后用fsck修复下试试

小悟空

命令格式？
直接输入 fsck  ？
提示如下：

fsck from util-linux-ng 2.17.2
e2fsck 1.41.12 (17-may-2010)
/dev/mapper/VolGroup-lv_root: cleam,80768/32768000 files, 847477/13107200 blocks
e2fsck 1.41.12 (17-may-2010)
/dev/sda1:clean, 38/12016 files, 44823/51200 blocks
e2fsck 1.41.12 (17-may-2010)
The filesystem size (according to hte superblock) is 13107200 blocks
The physical size of the device is 5242000 blocks
Either the superblock or the partition table is likely to be corruypt!
Abort<y>? yes

e2fsck 1.41.12 (17-may-2010)
fsck.ext4:No suck file or directory while tering to open /dev/mapper /VolGroup-lv _mylvm

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not sqap or ufs or something else),then the superblock
is corrupt,and you might try running e2fsck with an alternate superblock:
      e2fsck -b 8193 <device>



这个提示，因为有数据没备份，不敢下一步了，老大请指教
