reconfigure readynas 104
Posted elsewhere but hadn't considered business solutions - sorry. My readynas 104 was configured with disk 1 and 2 as raid 0 and disks 3 and 4 as two jbod volumes. I decided to split disks 1 and 2 a...

Thanks for the quick reply. The current situation is disks 1 and 2 are installed as 2 x jbod and I am restoring files to them as I write. So can I now return disks 3 and 4 without losing the data on them? I'm just worried that the factory reset may have done something that causes the nas to format them instead of simply mount them.

No, that is not what I said. Go back and read post # 2 again. Pay particular attention to the need to export the volumes.
You can of course back up the files on disks 3 and 4 when you boot up the system with only those disks in place.

The raid 0 volume no longer exists. I have now got disks 1, 2 and 4 all as single jbod volumes, and all are active and saving data. So my concern is can I return disk 3, containing data from before starting this evolution, into slot 3 and have the shares on it available again, or will it be reformatted by the nas? I am aiming for 4 individual jbod volumes.

How many times do I need to answer this? Here is the step by step:
- Power down the NAS
- Remove disk 1 and 2, add disk 3 and 4
- Power up and reboot the NAS (with only disk 3 and 4)
- Go to the volumes page in the web ui. You should see the volumes on disk 3 and disk 4 as healthy. The original RAID-0 volume will be inactive
- Optionally back up the files on these two disks
- Click on the volume settings wheel for disk 3 and choose Export
- Click on the volume settings wheel for disk 4 and choose Export
- Power down the NAS and reinsert disk 1 and 2
- Power up and you should then see all four volumes with no data loss.

I'm sorry I seem to be frustrating you - perhaps I'm having a 'senior moment'. 😞 There is currently no volume 3, just 1, 2 and 4, all newly created on clean disks as jbod after the factory reset. So I now only have disk 3 to insert back into slot 3, that has the original set of shares and data on a jbod disk. So I'm just checking that when I insert it into slot 3 the nas will recognise the original formatting and shares so that they are again available, or was there additional configuration that will have been lost in the factory reset to trigger a reformat of disk 3.
