ReadyNAS Pro Biz Edition upgrade from 6X2TB to ?
I have a 2009 ReadyNAS Pro Biz Edition that has six 2TB drives and it is running RAIDiator 4.2.22. I haven't had it on for awhile and quit using it because it filled up. I have a couple 3TB drives ...

Still not getting the math. at 14TB I already subtracted a full 4TB drive for redundancy. Then what is the additional 1.3TB being taken away?
14 TB and 12.7 TiB are the same amount of actual space, just reported using different units. Drive manufacturers always use TB. The NAS uses TiB, but calls it TB (as does Windows).
1 TB = 1000*1000*1000*1000 bytes
1 TiB = 1024*1024*1024*1024 bytes
To convert 14 TB to TiB, the formula is
14*(1000/1024)*(1000/1024)*(1000/1024)*(1000/1024) = 12.7 TiB.
There are similar mismatches for GB /GiB and MB/MiB.
Sorry, but the description seems overcomplicated.
What HDDs do you actually have in the NAS right now?
"4+4+3+3+2+2-4=14", what's that "-4"??
On XRAID, if you have 2x4TB + 2x3TB + 2x2TB, you should have a RAID5 of 6 partitions of 2TB (10TB capacity, 2TB parity) + a RAID5 of 4 partitions of 1TB (3TB capacity, 1TB parity) + a RAID1 of 2 partitions of 1TB (1TB capacity, 1TB mirror), with a volume capacity of 14TB.
BUT, we're talking about RAIDiator 4.2 here, not ReadyNAS OS6! Volume creation and expansion don't happen the same way.
On RAIDiator 4.2, (I'm gonna say "if I remember correctly", just in case, but I'm pretty sure that's it, it just has some time since I played with XRAID on that version), it starts by creating the primary RAID... and that's it. After it's fully resynced, then it will create the second RAID... and that's it. After it's fully resynced, then it will create the third RAID.
It might be necessary to reboot the NAS to trigger the expansion (it is actually handled like a vertical expansion, with its limits).
