I have a redhat linux server working as a backup server. After my coworker worked on this system, for some reason it couldn't start. Please see the following output for diagnose.
Activating Logical volumes
4 logical volume(s) in volume group "VolGroup00" now active.
Creating root device. Mounting root filesystem.
kjournald starting. Commit interval 5 seconds
EXT3-fs: mounted filesystem with ordered data mode.
Setting up other filesystems.
Setting up new root fs
no fstab.sys, mounting internal defaults
Switching to new root and runing init.
unmounting old /dev
unmounting old /proc
unmounting old /sys
/bin/sh: ro: No such file or directory
Kernel panic - not syncing: Attempted to kill init!
After these steps, the system just keep rebooting. Please advise what caused this failure and how to remedy it. Thank you experts!
