7.0.1 - Wrong pool state after replacing failed cache drive

Featured Replies

Hi, I had a cache drive fail. Unraid was still up and working, did a clean shutdown to replace and am now getting a "Wrong pool state".
I tried starting the array with the new drive, without the new drive selected, without either drive selected, in maintenance mode. Not sure what the next step is but really don't want to have to delete the pool and redo all of my dockers and such

Looked threw a couple of forum and reddit posts and those were the steps i understood how to do.

Thanks for reading and maybe helpingtower-diagnostics-20250503-2331.zip

Reimport the pool with the single remaining device, then post new diags after array start:

 

on main click on the first device for that pool and then "remove pool"
back on main, create a new pool with the same name and 1 slot
assign the pool device, leave the filesystem set to auto
start the array to import the pool
