I am trying to build all nvme unraid server. what will be the best practice - no cache drive - ZFS only - or now i can use normal unraid method with parity and array as usual? only going to it use for backup of some of the servers we have. Using amd epyc cpu supermicro board 128gb ram and asus 4 nvme pciex card dual 10gbit nic etc etc or i just look elsewhere and not even think about unraid. Planning to use unraid only for ease of use. want to automate all the tasks.

sorry its mapping to user/system/docker/docker/volumes/data/_data - which is not in usb but i want to map /appdata/ to portainer containers.

if i create a vol named "data" in portainer - it directly going in /var/lib/docker/volumes/data/_data - which is i think inside USB stick.

HI i have portainer BE license and how do i map /appdata/ folder as volume for other containers which i am planning to run via portainerBE ?
