June 7, 20233 yr I just replaced my unraid USB drive. The array itself is good, but my cache drive isn't. For some reason the config thinks that I'm still using an old cache configuration with 2 drives, whereas I have moved to using just 1 drive well over a year ago. However, the new USB config is looking for my 2 old cache drives not my single new one. The cache drive is successfully emulated by the array. How can I fix this? Can I just correct the cachepool.cfg file? Do I need do something else? Let me know what, if any, information you need. Thanks

Ah, well it says the cache drive is emulated and when I mounted the array it started containers. 8 minutes ago, trurl said: How did you do this? Uh, it's been a while and I don't remember exactly. I followed directions from the documentation on changing the cache drives. I believe it was these instructions: https://wiki.unraid.net/Replace_A_Cache_Drive Everything had been working for quite a while and the server had rebooted multiple times. 9 minutes ago, trurl said: attach diagnostics to your NEXT post in this thread Attached. skynet-diagnostics-20230607-0543.zip
June 7, 20233 yr Community Expert Solution Stop array, unassign all pool devices, start array, stop array, re-assign pool device, start array.

I'd guess not since you're recommending it, but I want to make sure I understand first. It would be a nice easy fix though, so I hope it'll work. I won't be able to try until after work today anyways so I've got some time.

Ok, I set both cache pool devices to "no device", but it won't let me start the array because cache drives are missing. Did you mean something else by "unassign all pool devices"?
