Hello,
I had set up a RAID 1 type assembly with 2 disks and made a backup on a 3rd disk by synchronizing it via RAID 1. Today, I broke / rebuilt the RAID 1 and formatted the 2 disks. I want to synchronize the 3rd disk with data on the currently empty RAID 1.
My question is as follows: if I position the 3rd disc which contains data in place of one of the two empty ones in the NAS, the synchronization will be carried out well from the 3rd inserted disc (with data therefore) to the one which was already present and empty?
I'm afraid that the synchro will be done the other way and that the 3rd disc will be erased.
If this solution is not correct, can you please tell me how I could proceed?
Thank you in advance for your wise advice.
Have a very good day everyone.
Eric

Exactly so.
What you'd need to do is
destroy the RAID 1 volume (switch to flexraid, then click on the volume settings wheel. Then you'll see a destroy option).
power down and remove both disks
boot up the NAS with the 3rd disk in place by itself.
After you verify that the data is there, then hot-insert one of the new disks. It should start syncing automatically - if it doesn't, then select the new disk on the volume tab, and click format.
After that is synced, then you can hot-swap the 3rd disk with the other new one, and wait for that to sync again.
FWIW, the original method of making the backup isn't the best. It's much better to use a backup job to copy the files to a USB drive or network share.
