Here has entered the rescue mode.


To switch the root directory:

Chroot/mnt/sysimage

To start the SSH service (or not to start):

Service sshd Start

To mount a disc:

Mkdir-p/mnt/cdrommount/dev/cdrom/mnt/cdrom

Re-install the kernel:

CD/MNT/CDROM/PACKAGESRPM-IVH kernel-2.6*--root=/--force

After the installation is complete, view the partition (I am the LVM partition):

ls/dev/mapper/

Kernel line does not show full, followed by Volgroup-lv_root, that is, the path of the root partition, and enforcing=0 (not likely to boot boot)

When you are done, enter:

Boot

Start

It may be a little longer here, after the disk is re-labeled.

When you are finished, you can enter the system normally:
