So I screwed up majorly when adding a new hard drive to a server. I accidentaly ran fdisk on an existing partition, it told me it was not recognized, and so I pressed w to write.
Now when I try to book I get the error:
ALERT! /dev/mapper/LI--MAIL-root does not exist. Dropping to a Shell!
Grub also tells me :
Partition hd0, msdos5: not a known filesystem.
Unfortunately this is a live server that I need back up and running as soon as possible. I have spend the last 2 hour scouring the web for help. Please if anyone has any idea on how I can get this working again please help.
