I am not the roiginal poster, but I am doing something very similar and can answer that question for you. Some people get paranoid about the whole "single point of failure" thing. I originally suggestted that we buy a filer and have identical servers so if one breaks we connect the other to the filer, but the response I got was "what if the filer breaks?". So in the end I had to show we have duplicate independent machines, with the data kept symetrical on them at all times. It does actually work quite nicely actually - I have an "'active" database machine, and a "passive". The opassive is only used if the active fails, and the drives are run as a gmirror pair with the remote one being mounted using ggated. It also means I can flip from active to passive when I want to do an OS upgrade on the active machine. Switching takes a few seconds, and this is fine for our setup. So the answer is that the descisiuon was taken out of my hands - but this is not uncommon, and as a roll-your-own cluster it works very nicely. -pete. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
