Volume Expansion question
Hi, I have a Readynas 3200 with OS 6.9.5 HF1 and up until some days ago I have 12 2Tb discs using X-RAID2 with a total of 18,15 TB. I now installed 2 new 6TB discs and though that after rebuild wou...

I think StephenB got the math wrong and the volume will expand by 8TB (assuming you've got the standard RAID6). Still, since only bays 1-3 can handle a disk >2TB on a 3200, you might want to consider higher capacity drives. But you will need 4, so you'd have to figure out what to do with the the 6TBs you already bought.

I now installed 2 new 6TB discs and though that after rebuild would expand the volume but it doesn't!
My questions is:
1. Should it automatically expand the volume with this new added space?
2. If Not...How many 6 TB disc to I need for it to happened?
You are running RAID-6, so the four largest disks need to be the same size.
After you upgrade two more disks to 6 TB, the volume will expand by 4 TB to 24 TB (~21.8 TiB).

Well that sucks that I can only use bays 1-3 for larger discs.
Anyway....Thanks for your replies...both You and @StephenB.

I thought the 3200 could handle > 2 TB drives in bays 1-4 ???

Correct. I'm not sure what made me put 1-3. They use a different onboard SATA controller than the other 8.
