Kernel panic and bad block after update /etc/updatedb.conf

Hi,

I have update my updated.con file with the parameters cvfs . CVFS is the File system of Quantum Storage Manager.
Server HP Proliant 380 G8, RHEL 5.4.

This to avoid, like is written into Quantum documentation, to create an index on FS many large:

RedHat Enterprise Linux 4, 5, and 6
Add “cvfs” to the list of file system types to be
skipped. This is usually done by modifying the
“PRUNEFS” line in the /etc/updatedb.conf file to read:
PRUNEFS=”cvfs sysfs selinuxfs usbdevfs
devpts NFS nfs nfs4 afs sfs proc smbfs cifs
autofs auto iso9660 udf”

This operation was made by me also in other installation without problems.

Yesterday after done it into 4 server none of this were able to reboot again.
At boot Linux gave me Kernel panic, problems about Logical VolGroup00, Bad Block and freeze the pc at boot.

There is anybody that have had a similar behaviour ?
I'm not skill about Linux. Is there the possibility to boot with a minimal configuration ( like windows ) to try to delete the parameter into the file updated.conf ?

Thank you
