I'd recomend drbd over a nbd + raid solution: * drbd knows to read from local device only so performance is generaly better * it deals nicely with disconnect / reconnect scenarios. I've used drbd in real-life configurations with linux FailSafe and with heartbeat as cluster managers, works quite nicely once you get it running. Problems with drbd: * current version doesn't like SMP * works at block level, so speed for a full synchronisation depends on filesystem size, not just used space. * resync speed limited to about 4MB/sec - limit aplies only for resync, not for normal read/write access. have a look at http://www.linbit.com/en/ for more information.
