I agree that you don't need LVM (if that's what you meant). I do think
you need a journalling filesystem.

However in the present case it's conceivable that the power fail did
some damage to the actual drive, especially if there was also a power
spike, in which case a journal may not save you. You might have better
protection with a mirrored drive, but really there are no guarantees.
Backup often.
