SERVER IS NOT GETTING START AND SHOWING THIS ERROR
EXT3-fs: unable to read superblock mount: error mounting /dev/root on /sysroot as ext3: Invalid argument Setting up other filesystems. Setting up new root fs setuproot: moving /dev failed: No such file or directory no fstab.sys, mounting internal defaults setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory Switching to new root and running init. unmounting old /dev unmounting old /proc unmounting old /sys switchroot: mount failed: No such file or directory Kernel panic - Not syncing: Attempted to kill init!
Note: actually this problem is coming when superblock of root partition are crrupted. therefore you are not able to mount your partition because file system of that partition is not working properly.
Sulation:-
Step-1. Go to rescure mode through CentOS DVD.
Note: If your Hard drive is not detecting/showing in rescure mode then boot from Ubuntu live Dvd for temporary use Ubuntu.
Step-2. Use following command to recover superblock.
#dumpe2fs /dev/sda2 | grep superblock
#fsck -b 32768 /dev/sda2 or #e2fsck -b 32768 /dev/sda2
Now reboot sysytem...
