Hmmm. Alright, but supporting hot-swap isn't the issue, is it? I mean, like I said in my response to myxiplx, if I have to bring down the machine in order to replace a faulty drive, that's perfectly acceptable - I can do that whenever it's most convenient for me.
What is _not_ perfectly acceptable (indeed, what is quite _unacceptable_) is if the machine hangs/freezes/locks up or is otherwise brought down by an isolated failure in a supposedly redundant array... Yanking the drive is just how I chose to simulate that failure. I could just as easily have decided to take a sledgehammer or power drill to it, http://www.youtube.com/watch?v=CN6iDzesEs0 (fast-forward to the 2:30 part) http://www.youtube.com/watch?v=naKd9nARAes and the machine shouldn't have skipped a beat. After all, that's the whole point behind the "redundant" part of RAID, no? And besides, RAID's been around for almost 20 years now... It's nothing new. I've seen (countless times, mind you) plenty of regular old IDE drives fail in a simple software RAID5 array and not bring the machine down at all. Granted, you still had to power down to re-insert a new one (unless you were using some fancy controller card), but the point remains: the machine would still work perfectly with only 3 out of 4 drives present... So I know for a fact this type of stability can be achieved with IDE. What I'm getting at is this: I don't think the method by which the drives are connected - or whether or not that method supports hot-swap - should matter. A machine _should_not_ crash when a single drive (out of a 4 drive ZFS RAID-Z array) is ungracefully removed, regardless of how abruptly that drive is excised (be it by a slow failure of the drive motor's spindle, by yanking the drive's power cable, by yanking the drive's SATA connector, by smashing it to bits with a sledgehammer, or by drilling into it with a power drill). So we've established that one potential work around is to use the ahci instead of the pci-ide driver. Good! I like this kind of problem solving! But that's still side-stepping the problem... While this machine is entirely SATA II, what about those who have a mix between SATA and IDE? Or even much larger entities whose vast majority of hardware is only a couple of years old, and still entirely IDE? I'm grateful for your help, but is there another way that you can think of to get this to work?
