Just need an ordinary Linux PC with a reasonably up to date kernel, and to install mdadm and btrfs-progs (if they are not already installed).

Hello mdgm, just a clarification on this matter.

Assuming I have this scenario: a RN102/104 equipped with 2 HDDs or a RN312/RN314 (maybe valid also for a RN316) equipped with 4 HDDs both configured with so called - AFAIK default, "X-RAID" (and BRTFS as factory default filesystem for data) and I want/need to recover data from them because things went badly wrong.

Question (maybe silly): Have I to pull out all involved ReadyNAS HDDs and push them in into a suitable Linux box (with enough SATA ports available) respecting exact ReadyNAS HDDs install order and exact HDDs quantity (so, as example, equipping the Linux box with HDD 1 and 2 from a RN102/312 fully filled or with HDD 1, 2, 3 and 4 from a RN104/314 fully filled) so to have, on the target Linux system, new devices sdb/sdc or sdb/sdc/sde/sdf (considering sda used by my Linux distribution for its OS)?

The question above should be also valid if I have a 3 HDDs configuration (or a different one, as example, 2 HDDs on a RN104/RN314) too. Thanks!
