Sure, I'm definitely not disagreeing with anything you're saying here. I'm
inclined to think I have just been lucky the few times I've had to do this
in the past, and to maximise my good luck I should take the same
precautions that you do in the future :-)
I haven't played with gvinum yet either, but I'll probably be looking at a
hardware solution (FreeBSD-supported hardware RAID or network-attached
storage appliances) when the time comes to replace these servers. Vinum
has been excellent, but I always find it really traumatic to deal with,
mostly because I have to touch it every 6 months at most. There's always a
frantic hour re-reading the documentation, followed by a lot of "I really,
really, hope this works" moments before hitting Enter :-(
