Thanks for all replies .
Today, I did the following things,and also met the other errror message:
<snip>
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
<snip>
It is obvious that the fsck command maybe not to use .
What could i do now ?
Maybe it is the only method to reinstall the CentOS operating system. isn't it?
That looks like you either have a physically bad hard disk, or directory/inode corruption in the entry needed to load fsck. Try running
<snip> Looks to me as though you definitely have a hard drive going bad. The thing that says that to me is "unable to read", not "error reading". I'd reboot from a DVD with linux rescue, do *not* mount the filesystems, and do an fsck -c (and any other options) on all the partitions that are formatted. This will check for bad blocks. If there's only a few, say, 1, or 10, note how many of them there are, and let it take its default to mark, and then fix everything else. If there's a *bunch* of them (100+), you need a new hard disk, now.
