ReadyNAS Volume not expanding - with encryption
 Don't not the exact Pro 6 Model..     I've got a Pro6 with  2x 2TB and 2x 3TB     All worked fine except the XRAID2 isn't working.. at least not how expected.  I've installed ReadyNAS OS6 with factor...
- Mar 29, 2017md1 is the swap volume, so no need to touch that. If the volume is encrypted, X-RAID won't be able to create sub RAID arrays on unused disk capacity in case of mixed capacity HDDs. It's just not compatible. This is why the logs say " Skipping X-RAID auto-expansion on encrypted pool data Your solutions: use disks of the same capacity, or create separate encrypted volumes, or don't use volume encryption.

- chsu83Mar 29, 2017Luminarythank you for that.. good to know. yep.. the swap I only touched because I thougt if something is checking raid level of different raids.. and only if all ar good and in same way configured then the expansion starts.. thats why I tried to make them similiar. The statement, I've seen later :) Skipping X-RAID auto-expansion on encrypted pool data - chsu83Mar 29, 2017LuminarySo then.. cool feature.. personally I think its a cool implementation of it. Would perhaps be great for some situation, that there is a mini webservice to submit the key in the boot process without a key. Unfortunately this situation I couldn't thest via the VM, because I didn't now how to propagate the USB Stick. Perhaps some time the possibility will come use XRAID with uneven disks and encryption. Or enabling/disabling encryption after creation of the volume.. *hoping* Thanks to all of you, made the OS6 possible on legacy devices. I'll have to think to destroy the volume, or buy new Harddisks.. :S - bad situation, if you got enough place with the cool XRAID :) - jak0lantashMar 29, 2017Mentor
