Thanks Chris I should've browsed recent threads, my apologies. Terribly frustrating though that the issues you refer to aren't documented in the btrfs wiki. Reading the wiki one is lead to believe that the only real issue is the write hole that can occur as a result of a power loss. There I was thinking I've a UPS attached, no problem. Notification and handling of device failures is fundamental to any raid system, so it seems it's nowhere near ready.
