I have a Duo 1 with 2 mirrored disks and I would like to remove 1 to use as a back up disk in a USB drive for something elseIs this possible and if so what do I have to do.I realise I would loose security by only running 1 drive but that would be ok

All you actually need to do is remove it. The duo will put the volume in a "degraded" status - and it will stay in that state forever. It's best to pull the parity drive (which is normally drive 2).Given the price of new 2 TB drives ($60-$70 street price in the US), I wouldn't do this myself.

Nor would I.Is the data on the duo backed up, or would you be happy to lose it?

The process requires a factory reset.(a) save the config, note any add-ons(b) reset with one disk in place (can be done from either frontview or the boot menu).(c) choose "flexraid" and RAID-0 via RAIDAR within 5 minutes or so of the reset.(d) reinstall the add-ons (the order matters for this step!).(e) restore the config(f) restore data from the backup.This would allow you to add a second disk (its own volume) later on, and increase the storage of the NAS up to 4 TB if you wanted.This of course can be done at your convenience (e.g., you could pull the parity drive now, and reconfigure as jbod when you need the storage).I've rebuilt my own duo as jbod - at this point it is only for backup, and I needed the space more than the RAID protection.

I wanted to repurpose a 2TB drive myself and I thought that removing it would have my 516 just rebuild, but it's still in Degraded state. Is there no way to force a rebuild?

I'm trying to force it to remove one disk from a 5 disk X-RAID setup. It even has enough free space where it wouldn't miss the disk I'm trying to remove.

You can't shrink the RAID. X-RAID is eXpandable RAID not shrinkable RAID.

Hi, I have a similar problem. I have 2 ReadyNAS Duo v1 at home, the first with two 1Tb disks in X-Raid configuration and the other one with two 2Tb disks always in X-Raid configuration. I normally use the first NAS for my daily needs and periodically backup the first NAS to the second via Frontview Backup (Rsync mode). I don't know if this is the best way to use my 2 NAS so I really appreciate if someone would like to give me tips.
By the way my question is which would be the right way to upgrade my disk dimensions in the first NAS in order to not lose any data/configuration. I'm going to buy now only one 2Tb HDD due to economic issues and 1/2 months later I'll buy the second one.
Thanks
