Taking out a cache pool drive without loosing any data

[drydenmike]

Basically what's in the title.

 

I want to know the procedure to take a SSD out of the cache pool without loosing any data... I have 2 disks in that pool, a sata ssd and a nvme m2 ssd. I'm not planning on replacing it or something, just want to take ou the SATA one.

 

Is there a way to do this or am I going to lose my data? In there I have the "domains" share with all the VMs and apparently the appdata with the docker container configurations, as far as i can tell, but the occupied space in there fits the space on the one that's left.

 

Thx in advance

Before you follow through, you may want to wait on @JorgeB to comment on whether the procedure is working correctly on the version of Unraid you are running. You didn't post diagnostics, so it's impossible to say whether it will work for you.

[JorgeB]

Don't remember any recent issues with device removal, there were with device replacement, just check that the pool is using just one profile for data and metadata and it's one with redundancy, or post the diags so we can check.

The issue with pools not being redundant despite appearing to work properly was prevalent a year or two ago, now that JorgeB mentioned it. If you can't determine that yourself, attach diagnostics to your reply to this post.
