RN214 Drive issue -- Can I move them into 6 bay system
I have two RN214 with 4 drives in each system, set for Raid 5
In one system, the drives have filled up, and the disks are not seen. With error saying a new drive needs added.
Since the d...
Ok.. I made the purchase of the 426, and two additonal 6TB drives (the other 4 where 6TB drives).
Put all the drives in with the two newer ones in the bay 5 and 6. I belive the others are 1-4 in order.
I was able to do the firmware upgrade via Raidar, but I can't connect to the admin page. See the attached for what I see.
It appears the drives are properly seated and recognized, but not added to the pool?
You were able to access the web ui before you moved the drives?
To be honest, I'm not sure. I put the drives in before I powered it on.
I've got a support ticket opened. It appears they will need to do the upgrade, because of the Arm to Intel change.
Thanks!

Is your data backed up?
This looks like a data recovery situation:

Data recovery attempts (support would explain what the costs involved are and that the attempt may ultimate prove completely unsuccessful) are best done with disks in a x86 ReadyNAS such as your RN426 as those are more powerful so I would leave your disks in the RN426.
So if you don't have a backup you might need to get some disks for the RN214 and provide that storage as a backup destination for a data recovery attempt.
As you've got 4x6TB disks that are very full, it'd be best to put 4x8TB (or larger capacity) disks in the RN214 as 6TB disks in RAID-5 wouldn't provide enough storage. It's best to keep volumes less than 85% full.
