Planning Ahead for Capacity Upgrade
Well, the ol' 4TB based volume in my 516 is down below 3TB free space. FWIW, this somehow got created as a RAID-5 under X-RAID2, but with 4TB disks it wasn't so bad. After some thought and looking at...

The volume will only expand when redundant space can be added. So if you have one 12TB disk after the RAID-6 volume is rebuilt you will still have dual-redundancy.
After you've created the RAID-6 volume you can re-enable X-RAID.
In fact depending what disks are installed, with a RAID-5 volume with three or more disks you could disable X-RAID and designate it so that when the next empty slot is filled it is used to add parity (i.e. convert to RAID-6). This conversion does take a long time though.

Nearly 70% today... and then a bad turn. Someone turns off the power strip with the NAS on it. I find it later and it boots up with volume mounted, but resync doesn't seem to be running despite showing 69.4% completed. I try for clean restart from web interface and it comes up with no data volume. Shows "offline" volume with all the drives in it, but not sure how to proceed.
Submitted SR 27783352 and waiting to hear back. Logs and diagnostic access included.

Hi btaroli.
Given the event that occurred and as well as its result it was a good idea to get support already. I would have advised to do so if in case.
They should provide updates once the checking on the back-end is done.

Well, sadly, it was not to be that the raid5 to 6 conversion could be safely resumed, and it's not entirely clear why it failed to recover after the apparent power event. But the good news is that the support heroes did get the volume into read only mode and we were able to spare 12TB of data from a ghastly fate. I've destroyed and re-created the "data" volume on the affected device and it's already gotten through 63% of the initial resync /while/ 12TB and over 3M files copied back to it in about a day.
So if faced with the prospect of migrating existing disks and coverting to raid6 when enough storage and different NAS heads are avilable to build fresh and copy data, I know which route I'LL take. ;) It's all a learning process, after all. :D
