Need help with ReadyNAS Pro expansion

I need assistance with making a 6th drive expand on my Pro Pioneer Edition with Radiator RAIDiator 4.2.21 (just updated to from .20)

I had (4) 1TB Drives for quite sometime and recently purchased (2) more 1TB to max out the six slots.

I wasn't aware that I should have done 1 drive at a time, but inserted both at the same time. I also tried the following the recommendations:

1) Unchecked both Disable full data journaling and Disable Journaling checkboxes
2) Unchecked Enable disk spin-down
3) Unchecked Disk Scrubbing and Online File System Consistency Check
4) Rebooted multiple times with Check and fix quotas on next boot and still I get a maximum of 3688 GB

I get this in the VOLUME SECTION:

Disk space

2265 GB (61%) of 3688 GB used

RAID Configuration
Configuration: RAID Level X-RAID2, 6 disks
Status: Redundant
RAID Disks:

Ch 1 : WDC WD10EADS-00P8B0 [931 GB]
927 GB allocated

Ch 2 : WDC WD10EADS-00M2B0 [931 GB]
927 GB allocated

Ch 3 : WDC WD10EADS-00M2B0 [931 GB]
927 GB allocated

Ch 4 : WDC WD10EARS-22Y5B1 [931 GB]
927 GB allocated

Ch 5 : WDC WD10EADS-00M2B0 [931 GB]
927 GB allocated

Ch 6 : WDC WD10EADS-00M2B0 [931 GB]
927 GB allocated


I expect to have at least 4.6TB of free space!

Any ideas?
