Today, I did the following things,and also met the other errror message:
First, I used the CentOS 4.6 DVD to boot for the linux rescue and then i copy all data to the another server
Then, reboot the server and then boot it from the hard disk.
This time, the screen came up with these:
Checking root filesystem:
----------------------------------------------
EXT3-fs error (device dm-0) :
ext3_get_inode_loc: unable to read inode block -inode=7473432, block=14942282
fsck: error while loading shard libraries: libuuid.so.1:cannot open shared object file:
Input/Output error:
*** An error occured during the file system check.
*** Droping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance
(or type Control-D to continue)
--------------------------------------------------------------
What could i do now ?
Maybe it is the only method to reinstall the CentOS operating system. isn't it?
