I've posted a few times lately. I'm trying to vertically expand my RN104. I had two 3TB drives and two 4TB drives. Everything was running fine. I decided that I wanted to try vertical expansion because I was running out of space.
I bought two 6TB drives. When I put in the first one, the drive appeared but it was black and the system wouldn't start integrating it into the volume. I ultimately ended up pulling the new drive and trying the second 6TB drive. It worked and the resyncing process finished successfully. I decided the original 6TB drive was bad and got another one and inserted it into the spot occupied by the existing 3TB drive. I immediately noticed that the LED for the drive in the third bay went out. It said that the third bay drive had been removed. I never touched it. So, I panicked and pulled the new 6TB drive and removed and reinserted the original 4TB that it said had been removed.
Well, now the three remaining drives are all red. And it says that it's trying to recover data. Which sounds good until you look at the Admin console and see that there are two volumes showing and it seem to be rebuiling a small volume of less than 2TB. It has given the error to remove inactive volumes to use the disk. Disk #1,3,4. That error repeats about every 20 seconds.
I have no idea why it disconnected from the exisitng drive when I inserted the new one. But, is there anyway I can recover the old volume from the three original drives? I've rebooted once and got into the situation I'm currently in. Any ideas to have it realize that it's got the three drives that were good before the attempted upgrade?
If you have a backup, then the simplest way forward is to do a factory reset with the final disks in place. Reconfigure the NAS (including recreate the shares), and then restore the data after the sync completes.
If you can connect the three disks to a Windows PC (USB is ok), then you could alternatively try to recover the data with ReclaiMe ( https://www.reclaime.com/ ).
