Reformatting Issue
Hello I had 2x2TB drives and 3x3TB drives (starting from a 2TB drive) added to a Readynas ultra 6. In the x-Raid2 configuration, it gave me 9250GB usable capacity. I have used 9000GB so I decided to...

Only reformatting method I can find is to add these previously formatted drives into a driveless ReadyNAS and factory reset it. If this is the only way then do I have to execute the following extra steps?
I am assuming 6TB and 3TB backup is being done externally (in a USB enclosure, or temporarily connected to a PC). Is that correct?
After the restore, you can simply hot-insert (or replace) the drives into the NAS. OS-6 will detect that there is data on them, so it will not automatically add them. But you will be able to format them/add them to the array from the OS-6 UI. So there are no big hoops to jump through. Just make sure you do this one drive at a time, and wait for the resync to finish before doing the second drive.
Though only 3 TB of the 6 TB drive can be used initially. So 2x2TB+4x3TB will give you the same volume size as 2x2TB+3x3TB+6TB (13 TB). 1x2TB+4x3TB+6TB would give you a 14 TB volume. If budget permits, perhaps get two 6 TB drives, and go with 2x6TB+4x3TB (18 TB volume). Though you can migrate to this later on - and OS 6 has no known expansion limits.

Great!
Thanks StephenB!
So it is ok to remove the 3TB drive from the current configuration, right?

Yes, I will use the 1x2TB+4x3TB+6TB config for now and eventually replace the remaining 2TB with a 6TB when budget allows.

It should be, though I'd backup up to the 6 TB drive first.
