Recently I upgraded the drives and wanted to get my data back. I figured I could just plug in one drive, but I found that the volume simply would not mount. I tried the other drive alone and got the same thing. Plugging in both at the same time and the volume mounted without issue. I used raid 1 because I figured that if one drive failed I could simply use the other. This recovery scenario makes me think this is incorrect. Am I misunderstanding btrfs raid? Is there a process to go through for mounting single member of a raid pool? Thanks, Jon
