But it'll require more devices than a raid56 would... And also with such large storage stacks with big drives, when they fail (note I use when not if) it takes a long time to restore. So if you have the ability to break them up and use something like GlusterFS to distribute it, it helps to mitigate this as well as other kinds of failures like power supply, logic board, controllers, and with georep even the entire local site. This is not meant to indicate the current layout is wrong. Just that there are other possibilities to achieve the desired up-time and data safety. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
