> I wanted to do something like this, but after reading about the failure rates of drives and raid, once one disk fails, it seems like you're fucked. Anybody got some stories or numbers that prove that while repairing my raid for one disk failure I won't just destroy the rest of my drives? Yeah, I've recovered several failed drives without issue, even on LVM systems where some partitions failed because they were striped but others worked because they were mirrored. No real issues overall. The only case where you might run into problems is when you get conflicting data between 2 drives, but I've never seen that happen in the real world. Some people will scare you into thinking that happens often but it hasn't been my experience. Often one drive just goes kaput completely or has an entire section which is completely unreadable or extremely slow, for which recovery is just a matter of marking that drive offline, swapping a new drive in and telling it to rebuild. The only case in which you lose everything is if you use RAID0. If you can do RAID10 that's the way to go IMO. RAID5 can be a little riskier because if one drive is damaged and one fails then you can wind up losing the bunch, but I use it on my personal NAS because it's mostly just TV and the important stuff is syncthing'd to my other machines. Regular scrubbing prevents these issues usually.
