After a power failure in my building, my SL 6.4 (x86_64) is experiencing a
kernel panic in the first stages of booting.
Error messages suggests that a serious problem occurred with my Ext4 filesystem
in /dev/mapper/VolGroup-lv_root.
Here are the error messages aftes the kernel panic:
ata3.00: status: { DRDY ERR }
ata3.00: error: { UNC }
ata3.00: exception Emask 0xoSAct 0x0 SErr 0x0 action 0x0

EXT4-fs (dm-0): error
loading journal
mount: wrong fs type, bad option, bad superblock on
/dev/mapper/VolGroup-lv_root,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Rescue disk says that I "don't have any Linux partitions" and I need to rescue,
at least, two MySQL databases in this server.
Can someone, please, provide some help with this case?
