Reconnecting to old volumes after swapping in old drives

Hi pjanjic

 

Welcome to the Community!

 

Your drives have been swapped out so inserting it back to the NAS might not be a good way to recover the data on the volume as it might be detected as new drives and get reformatted.

 

I would suggest trying to check the drives and recover the volume data first by using ReCLAIMe or other recovery options suggested in the community.

 

 

Drives taken out of the 2120 might also work using another 2120 but again, it is still wise to check on your data and recover outside your NAS before doing anything.

 

Hope this helps!

If you did an "Export" before removing them, then all that is necessary is to re-insert them with power off and power on.  If you did not use the export function and they were not the primary volume, you can likely also just re-insert them with the power off. If they were the primary volume, then you need to remove all the drives and put in just the two old ones, then recover data to another device.  If they were not the primary, you should also be able to install just those drives and boot, then restore data to another device.

 

You may want to try these in read-only mode first, just to be sure it works and tne NAS doesn't try to reformat them, though it shouldn't when it sees a system partition on them.  Worst case, it would just indicate they are used drives.  If not in read-only mode, it will also install the OS that's currently on flash to the drives.
