You set it up in flexraid mode? 

Do you have one volume or two?

Will the system let you switch to xraid?

Also, you should have 5x2TB RAID-5 in the first group, and 2x1TB RAID-1 in the second group. 

It looks like you might have tried to add a group instead of choosing expand.  Though it is possible that FlexRaid is expecting you to add a 3TB drive.  There is a comment in the optimization guide that suggests that:

drive per RAID group. (page 7)

If the system will let you switch to XRAID, then I think you can just hot-insert the disk, and add it to the array.  You'll likely need to format it on the volume tab first.

You could also copy off the data again (this time to a 3 TB drive), and destroy the current volume, and create a new one with 4x2TB+1x3TB using XRAID.  Then hot-insert the remainin 3 TB drive.

If you can back up the data, then you could try using ssh to manually expand group 1.  Sandshark can probably give you the commands you'd need - but you'd be on your own, and he can't test them for your specific situation.  Doing this incorrectly could easily result in loss of data.
