Hi, I'm a new user to unraid. I have a few disks and I've only created one share. No running VM's or dockers. 

 

As soon as I change the cache to "prefer" on that share I've created, the cache is being filles up automatically by files from that share. 

 

If I activate the mover, is seems to create an endless cycle of the mover trying to empty the cache, and the cache filling up with other files. 

 

I've tried disable the cache on the only share that I've activated it. It stops moving files to the cache, and I'm able to move the files back to a disk using midnight commander. I am moving them from /mnt/cache to /mnt/disk# if that is relevant. And the same thing happens again as soon as I reactivate the cache. 

 

I would like to be able to use the cache, but an hour after activating it, it's filled up to 100% and stays there even if no files are being copied to unraid. I've tried letting the mover do it's thing for 12 hours (activated to run every hour) but the cache stayed at 100% and the mover was still running. 

 

I can't find anything on this forum or google about that particular situation, I would need assistance on the matter. 

 

I have attached the system log to the post, but the cache wasn't activated at the time.

 

Thanks in advance.

Cache-Prefer means try to keep the files on cache. Cache-Yes means move them to the array.

Instead of syslog, we much prefer the complete Diagnostics zip, which includes syslog, SMART for all attached disks, and a lot more information about your hardware and configuration.

 

Go to Tools - Diagnostics and attach the complete Diagnostics ZIP file to your NEXT post in this thread.

Oh I've completely misunderstood the explanations on the cache setting. I've set it to yes, and it now works as expected. 

 

Thanks for both explaining the setting, and for the diagnostics zip, I will use that one if I need more help.

appdata, domains, system share will typically be cache-prefer so docker/VMs will not have performance impacted by parity, and so they won't keep disks spinning.

 

Have you tried setting up dockers or VMs yet?

Good trick I will set those shares to prefer. I had changed them to no when I was diagnosing my problem with the cache drive. 

 

I did setup a windows VM just for fun and it works very well, now that my server works like it should I'll try to add a bit more functionality to it, like transfering my Pi-Hole from a Pi to a docker. Fortunately I have a bit of linux background since I ran my fileserver on linux a few years ago and it helps me understand how Unraid works.

 

Unraid is a godsend for me as administrating a linux machine only as a file server was very difficult and a constant pain, adding new services kept breaking others, and I always dreaded updates because once in a while it broke functionality. I spent countless hours searching forums and google for ways to fix problems, but unraid installed and worked perfectly out of the box.
