Please use code tags for code,

It says "exec of init failed", which is the executable program Linux runs on boot after it has mounted the disk, so it appears to be finding a volume, but not finding /sbin/init inside it. This suggests to me that either

a) It is attempting to boot from the wrong volume

or

b) Some sort of disk corruption has removed /sbin/init from the correct voluem.

(a) might mean the correct volume is unavailable -- causing it to go to the next one. Or that the order of the volumes has changed, due to something being detected earlier than it was before. Have you made any disk changes to this server recently?

I would suspect (b) would warn you that the disk was not properly unmounted, but won't rule it out either.

Either way, I think you'll need a rescue CD to solve this, something to boot into and examine your disks. (not alter, unless you're VERY sure of yourself. It'd be very easy to dig in deeper at this point.)
