Hi everyone,

 

I have two unraid trial servers setup and am evaluating how to setup my NVMe and SSD disks.

 

In both servers I have rust drives setup in zpools, so the question that I have is regarding how to configure the NVMe, and SSDs to store VMs and Docker containers.

 

On one of the UR servers I would like to run my VMs and Docker containers off of the NVMe, and in the other server I'd like to run the VMs and Docker off of an SSD.  Should the NVMe and SSD be a lone drive in the pool on each server, (which is how I currently have it configured 1 NVMe alone in the array with no parity on one server, and 1 SSD with no parity on the second server), or should I move the NVMe/SSD to a new pool outside of the array?

 

Once the NVMe, and primary SSD are allocated, I still have 3 SSD drives of different sizes that I would like to make use of, but am unsure where to place them.  I'm thinking to mount them all separately and create shares off of them.  All data on the NVMe, and all SSD's are backed up, so I'm not concerned about redundancy.

 

Thank you for any advise and suggestions you may have.

 

Cal.

 

Not an advice, just some thoughts -  since I'm currently (also) setting up a system dedicated to VMs only; I'm using an old Thumbdrive as only array drive, just to be able to fire up all the other Unraid stuff (KVM & Dockers of course). 2 NVMEs in a single BTRFS pool, since I like to have redundancy, and a BTRFS mirror seems to be more straight forward (and the Unraid array is not meant to provide trivial mirroring anyway).

 

My concern ist the Fuse layer, which ist imo still in effect, as long as drives are somehow managed by Unraid (like with Pools). My guess: It might be best (in terms of performance) to just set KVM storage up as "unassigned device(s)".

 

Maybe someone can shed light on how pooled drives are affected by Fuse when most (or any) IO is going to VM disk images...
