Does the BTRFS raid bug affect ReadyNas units?
Was just reading this today:
http://www.phoronix.com/scan.php?page=news_item&px=Btrfs-RAID-56-Is-Bad
https://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg55161.html
Does this affect the BTRFS implimentation used in ReadyNas OS 6?
No. We use mdadm for RAID and the BTRFS file system is used on top of that. The mdadm RAID is at a lower level than the filesystem. We've been using mdadm raid since 2008 (when we released the ReadyNAS Pro running RAIDiator 4.2.x). mdadm is very mature.
The combination of mdadm raid + BTRFS is better than mdadm + lvm + ext4
