Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I'm working on this emergency open wi-fi network project and it includes a local website (nginx + MySQL). In order to eliminate SPOFs, we're going to setup at least two of everything (server, switch, router, etc.).

This network is thought to work when an earthquake strikes and it's very likely to a server to go to down, if so, we need to be able to boot them up and be operating as soon as possible.

Do any of you know if any linux filesystem would work better than others in this scenario?

Most cluster-aware file systems are actually very good at dealing with outages as they're kind of expecting it, you get two or more servers dealing at the block-level with the same file system then it's there to handle outages right? That said just because they're good at dealing with outages doesn't mean they do that AND come back up quickly however, basically you can't have your cake and eat it. As such something like OCFS2 or Veritas Storage Foundation would be my suggestions.

We're going to be using Red Hat, so I've been reading a lot about GFS2, seems to be pretty much the same as OCFS2, right? –  Felipe Solís Nov 16 '11 at 18:04
    
They're similar yes but if you're using RHEL then they just bought gluster.org - which you might consider too. –  Chopper3 Nov 16 '11 at 18:06

Are you asking what filesystem is more tolerant of hardware failure? If so, the answer is pretty much "none". You'll have to get gear that's shock tolerant, either in the form of a rack with shock absorbers, a server room with shock absorbtion, or SSDs instead of conventional HDDs.
