Migrating from 2 × 1TB to 1 × 2TB
Hello, for some years already I have ReadyNAS Duo (SPARC aka v1). From the very beginning there are 2 disks of 1TB with X-RAID (redundancy).
The time has come to upgrade for more space. So I got one 2TB drive. What I want is to have all the same configuration of shares, accounts, rights, add-ons but with only one 2 TB drive in my ReadyNAS Duo and of course (almost) 2TB of disk space available for my data. I don't think I'll be buying second 2TB drive later for this unit but maybe one day if I can get one for free or cheaply then I'll put it there for redundancy.
So, what is the simple way of reconfiguring from 2×1TB to 1×2TB without factory reset?
Yes, I know that putting two 2TB disks would have given me 2TB of disk space with redundancy.
At this stage I don't care for redundancy. Neither I want to buy second 2TB disk.
What I want is to have:
1. all my configuration settings preserved,
2. 2TB disk space
3. ONE disk of 2TB capacity inside my ReadyNAS Duo (SPARC).
The question is: is there a way to get this without manually recreating all configs?
What will happen in that given scenario:
1. ReadyNAS is on with two disks of 1TB synchronized and redundant,
2. I hot remove disk no2,
3. I put new 2TB disk into bay 2,
4. ReadyNAS initiates and synchronizes new drive,
5. When sync is done I hot remove disk 1,
6. I reboot ReadyNAS.
Will it expand to 2TB then?
If it will not expand automatically, will it expand with manually initiated command? If so, how to do it manually?

Hello Poldek,
XRAID on Duo or any 2-bay ReadyNAS is mirror RAID. One disk mirrors the other. The volume capacity is equal to the smallest size of disk, which means if you are going to have a combination of 1TB and 2TB disks, you are wasting 1TB space of the 2TB disk as it mirrors the other.
Best thing here is if you are trying to expand the volume you need to have 2x 2TB and not just one.
To expand the existing 2x1TB space, just remove 2nd disk and replace it with the 2TB. Once it is done synching, replace the disk 1 with 2TB.
However, I strongly suggest you backup the data (as we always suggest to always have full backup) since this unit is a very old version that do not have XRAID2 which is essential when it comes to volume expansion. Having full backup will save you in case you encounter any trouble with the expansion.

I don't think that will work. AFAIK the NAS will not expand unless both drives are replaced with larger ones. X-RAID doesn't support reducing the number of discs or disc capacity.
If you hotswap your current disc 2 and replace it with a 2 TB disc the NAS will resync. When you remove the disc in bay 1 the NAS wil consider the volume as degraded as there is no longer any redundancy.
I doubt that rebooting the device will change this.
If you want to have the NAS running with just one disc you will have to do a full backup and then do a factory reset with the 2 TB in the NAS (And ONLY this disc). This will wipe all data and settings.
Hello lundmilo,
Thanks for helping to explain. :)
Regards,
Ok - so there is no other way for me than factory reset.
Then could you tell me please if:
1. After I made factory reset - is there any difference if I put the 2TB disk (as the ONLY disk in the NAS) into bay 1 or bay 2?
2. I saved not only data, but also settings somewhere else. After factory reset and now ONE 2TB drive I can run RAIDar and have few minutes to choose - what to choose: JBOD or X-RAID? Considering there will be ONE drive in the NAS, probably for long time if not for the rest of the life of this NAS, but there is LITTLE chance that someone will give me good 2TB drive as a gift, I'll not have other option to use it, so I'd put it into the NAS then.
Will there be choice of X-RAID/JBOD at all if there is only ONE disk inside?
3. I try do restore my config from a saved file - will it work with new bigger disk and just ONE disk (JBOD vs. X-RAID)?
Hi Poldek,
1. There is no difference whether you use bay 1 or 2.
2. It is up to you if you use XRAID or FlexRAID. XRAID if you are expecting to have an additional disk for the other bay. It is for redundancy and not expansion. Setting up the NAS always starts with volume creation where it asks which RAID you want to use.
3. See page 98 Back Up and Restore Settings in the user manual, it does not matter if you use XRAID or not as long as there is a volume created.
Regards,
I see - thank you very much.
So, another way round...
I remove both old 1TB disks from NAS. I put ONE new 2TB disk into NAS. It is initialised etc. I play with it for some time - I create accounts, put some data on it - I play with this new disk for some time to see how it works. Then I remove this 2 TB disk from the NAS and I put back two old disks into the NAS again. Will everything be the same, as it was before? I mean configs, data? Or the NAS will treat the old disk as new ones and initialise it from the beginning.
