Hi all, What am I missing or misunderstanding? I have a newly purchased laptop I want/need to multi boot different OSs on. As a result after partitioning I have ended up with two partitions on each of the two internal drives(sda3, sda8, sdb3 and sdb8). FWIW, sda3 and sdb3 are the same size and sda8 and sdb8 are the same size. As an end result I want one btrfs raid1 filesystem. For lack of better terms, sda3 and sda8 "concatenated" together, sdb3 and sdb8 "concatenated" together and then mirroring "sda" to "sdb" using only btrfs. So far have found no use-case to cover this.
If I create a raid1 btrfs volume using all 4 "devices" as I understand it I would loose data if I were to loose a drive because two mirror possibilities would be: sda3 mirrored to sda8 sdb3 mirrored to sdb8 Is what I want to do possible without using MD-RAID and/or LVM? If so would someone point me to the documentation I missed. For whatever reason, I don't want to believe that this can't be done. I want to believe that the code in btrfs is smart enough to know that sda3 and sda8 are on the same drive and would not try to mirror data between them except in a test setup. I hope I just missed some documentation, somewhere. Thanks in advance for your help. And last but not least, thanks to all for your work on btrfs.
