Re: storage
Network partition followed by database "failure" suggests some sort of clustered system with no split-brain protection. Two halves of one cluster each thinking they are the "one true cluster" and writing data to shared or replicated storage with no protection. It's a typical mistake made by home-grown cluster software that doesn't fail safe.
Plenty of ways to avoid that with decent clustering software, with or without ZFS.
