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...
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?
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.
Hello Poldek,
Data and settings are saved to the disk/s. So if you remove the new disk from the chassis and put the old one back in, it should still give you access to the data and still have the same settings, it is safer if you power off the NAS first before removing and inserting any of the disk. Also, make sure to take note which bay the old disk is situated, always insert it to same bay where it has been working.
Regards,
The net here is that to get what you want you need to save the data to external storage (PC internal drive or USB drive), and then do the factory reset with only one drive in place. There is no way around it.
If you choose flexraid, you'll be able to add the 1 TB drive back later on, and have a C volume with 2 TB and a D volume with 1 TB.
Does it mean that if I put one new 2 TB disk, then do factory reset, make new config and then put second disk into the NAS - let's say 1TB disk - then I have 2TB+1TB = 3TB disk space available ony my NAS for my files? Always thought that for a ReadyNAS Duo SPARC 2TB user disk space is maximum.
