Use nvme disk for cache

[BlinCT]

Hello everyone. 
I want to use the nvme disk for cache, but for some reason it says I don't have permission. 
I stopped the service, but it still says I don't have permission. 
Has anyone had experience with this and can suggest what to do?

Provide information if you want support. It is absolutely impossible to answer your question in this state.
Environment??? Windows, Linux, Docker, Promox ???? Jellyfin version? Config file or cache settings screenshot. Error log.
Commands that you tried. How is that drive mounted. List permissions on the folders....

That's basically all the things you have to find and show if you want an answer. And maybe you'll even understand the issue by yourself by gathering all that.

You are right, it was my mistake, I didn’t describe everything that was necessary.

My main system is Proxmox. I have a free disk on my computer, which I've divided into three partitions. https://ibb.co/cXsQjwz6 I'd like to use one of the partitions as the location for the /var/cache/jellyfin cache directory. I tried mounting the partition in place of the cache directory.
Maybe I'm doing it wrong to mount the partition this way?

root@jellyfin:~# sudo mount -t xfs -o defaults,noatime,nodiratime /dev/nvme0n1p2 /var/cache/jellyfin
mount: /var/cache/jellyfin: permission denied.
dmesg(1) may have more information after failed mount system call.
