upgrade storage readynas 212
Hi Not good with this stuff. I have a 212 with a almost full 6tb drive in bay 2 only and I want to increase my total stroage to 14tb so i purchased and added a 8tb drive. But the storage has not ...

It is configured to raid 1. How do i make it so it acts just like a 14tb drive rather than dulpicate now?
Unfortunately there is no easy way to undo your mistake - which was not
- switching to FlexRAID before adding the disk.
- creating either a second RAID group or a second volume on the 8 TB drive.
While it is possible to end up with a single 14 TB volume, I recommend against doing that. Setting up two volumes (one 6 TB and one 8 TB) is safer. If you go with a single volume that spans both disks, then you lose all your data when either disk fails. With two volumes, you only lose the data on the failed disk. The only real cost is that you have to manage the free space so that you have enough on both volumes. Occasionally that means moving a share from one to the other.
You will first need to back up your data to recover.
Then there are two approaches. The first is to:
- Switch to flexraid
- destroy the current volume (which will destroy the data)
- create the new volume(s), and put some shares on each.
- restore the data from backup.
The second replaces step 2 with
- enable ssh access for the NAS
- use linux commands to undo the RAID-1
- unformat the new disk
If you aren't familiar with linux, I don't recommend the second approach.
Thanks for comprehensive answer. Sorry I don't follow all this real well.
I'm keen to stick with original plan of mine as most data is a time machine backup from all my macs so all I would lose is a backup. I don't want to have a seperate disk as this would mean creating a new tm backup but rather just have one big one.
Can I just switch to flexiraid and somehow erase only the new disk and the add it to first (btw have no way to back the nas up)?
what steps would I need to take to erase new drive, and then add to older drive to make total of 14tb? Thanks again

No. You'd have to switch to flexraid, and then adapt the linux commands that Sandshark gave you to reverse the RAID-1. Then you could add the new disk to the first (expanding storage this time).
Thanks again but im afraid that is too compex for me and also not without risk of bricking from his comments.
So Im still at squre one-
Anyone got any suggestion how I can most simply set my NAS up as a 14tb backup. Im on a mac. I can lose all my data and start again if absolutely necessary?

If the linux commands are too hard for you, then that's what you'll need to do.
You'd switch to FlexRAID, destroy your current volume, and then select the first disk and create a jbod volume.
Then select that volume, and then choose "add group". You'll then want to choose "concatenated" to get a 14 TB volume.
