I was running a 1tb Nvme drive as a cache pool. It handled thenapp data, isos, system etc as well as downloads. It got a lot of use and ran quite hot, so I thought I’d get a second 500gb Nvme to handle the downloads share and hope the temperatures dropped.

 

Unfortunately, instead of adding the 500 gb Nvme as a separate pool, I accidentally added it as a second drive to the existing pool, where it was formatted as btrfs and went into raid configuration with the 1 tb drive. So I have 1 pool with 2 drives instead of what I wanted which was 2 pools with one drive each. 
 

Is there a way I can correct this and take both Nvmes out of raid?  At present, both have exactly the same content, obviously, which is only 9 gig or so on each drive, with nothing in the downloads share, so this would be a good time to correct my mistake, if somebody can help me by telling me how to do it.

 

thanks

Remove the drive you added from the pool. Then add it as a new pool

Thanks for the suggestion - I don't know what is going on but Unraid has started a Parity check for some reason. I'm stuck waiting for that to finish before I can get back in and sort out the pool drive situation.

You can cancel a parity check, but if it started because of an unclean shutdown you should let it finish, now or later.

Thanks Jorge - it says it was because of an unclean shutdown. so I'll let it finish. Don't know why it happened - it seemed to be overnight so I was in bed!
