Hi. First post, go easy on me!

I've been using Unraid for a few weeks now, made some mistakes, fixed some, learned a lot. My latest is leaving SABznbd downloader to fill my cache pool and expecting it to spill into my array, which it did. However, my docker containers became unresponsive because cache had run out of space and appdata share was set to cache only. Make sense... now.

My shares...

SABnzbd operates incomplete and completed downloads into media.

The cache is made up of 2 x 500GB SSDs which is great for redundancy for data (aka appdata (not sure why I renamed it from default now!)) and system, anything other than media(?).

Therefore, I think I should just buy 1 x 4TB SSD, place it on a separate pool and assign media to use it.

Regardless of whether 4TB is overkill, in principle is this sensible, won't work, or something in between?

Or should I be operating one pool and use sub pools which means buy something like 2 x 4TB SSDs? I've not read up lots on sub pools yet, sorry.

If you are running a pool for caching that might get rather full then you need to make sure you set the Minimum Free Space setting for the pool to a value that will stop this happening (something like twice the size of the largest file to be cached is a good start).

I was about to reply and say I am doing this but I've just realised I set the min size on the share and not the cache pool! I'll do this now. Thank you.

Many people seem to miss this😊

Unfortunately, this has not helped. The cache is currently 'full' (it's hit the min free space set of 30GB) and on opening Sonarr and Radarr they say 'unable to open database file'. Both containers are set up use data share set to cache only.
