Anybody know how big a volume I can create with Radiator 4.2.31?
I've got these Western Digital 6TB gold drives (please see attached file). Here's the thing. If I let the ReadyNas 2100 create an X-Raid2 volume it uses up all of the space, and then it says the ...
Thanks everybody for your advice.
The final number: 16,273,912 MB is what you would put in. That's including "10 GB" for snapshots, although I think the software is in error, I think that really means "10 %" for snapshots.
(If you put 16,273,913 MB that is the smallest size that is too big to be created into a successful volume.)
For ReadyNas 2100 v1 running Raidiator 4.2.31.

It would still be interresting to see the results of those commands to see what's causing that limit.
One reason for the inability to expand over 16 TiB is the inode size. The system uses 32 bit inodes if the initial volume is < 16 TiB, and that can't be safely changed later (at least in the ext software in the 4.2.x ReadyNAS). You need 64 bit inodes if the volume is > 16 TiB.
But in this case (4x6TB drives), the system should have chosen 64 bit inodes.
Interesting.

I haven't quite figured out how they got that number, but it's good info for anyone with an NVX, 1500, or 2100V1.

So a 16 TiB ceiling on the 32 bit 4.2.x NAS.
Grunchy: One option is to switch to flexraid with only three of your disks in place, and set that up as RAID-5 (volume c). Then hot-insert the last disk and set it up as RAID-0 (volume d). You'd get 12 TB in the c volume, and 6 TB in the d volume. You wouldn't have RAID redundancy on the d volume.
