how to vertically expand a ReadyNAS 104
I bought a ReadyNAS104 a couple of years ago with one 3TB disk.
Now that that disk is full, I bought another 3TB disk to increase the capacity to 6TB.
I stuck the new hard drive into the box, and...
If I remove the second drive and reboot the NAS, is there any way to get it back to a single disk system and start over?
Could I then make the system into a JBOD (or something) array and have it (re)format the second hard drive so I can use it?
There is no other way than to change to Flex-RAID and destroy the current volume created or do a Factory reset and start with Flex-RAID. The RAID is now RAID 1 so these are the only option :(
Both will be destructive so you need to do a backup.

So, if I have no choice but to add another hard drive, what options do I have with the drive: does it have to be exactly the same as the original disks (WD Red 3TB), or can it be just the cheapest I can find?
It would be better if you get the same drive as with the first two that you have :)
If you can avoid Desktop drives and go with WD Reds then it will be best.
OR you can disable XRAID add the 3rd drive, set it as JBOD then transfer the files and go DESTROY the other volume and set the other 2 again as JBOD,
But JBOD does not have any data protection, once it failed you don't have any data to be recovered.

If you need to get a different size disk (either bigger or smaller), then this might be a good approach. But if you are getting another 3 TB drive, you are better off sticking with XRAID.
As far as disks go, I have quite a few WD30EFRX deployed, and they've worked out well for me. A Seagate 3 TB IronWolf would also be a good option, so you could price them both. I don't recommend going with desktop drives. NAS-purposed drives like the Red and the IronWolf are much better choices.

Regards,I don't have any money to buy another hard drive at the moment, so this issue will remain unresolved for me until I can get another drive.

Which I guess also means that you don't have the ability to back up your NAS (since you could solve it w/o a purchase if you did).
I'd recommend investing in a backup plan before you expand capacity. Although RAID isn't enough to protect your data, it does offer more protection than jbod (which is what you had with only a single drive).
