New Single node Proxmox server with local storage.

[jim.bond.9862]

Hi everyone.

I have finally rebuild my home server to run Proxmox. been playing and planning to do it for very long time but never had time. no I do have some free time so start moving.

my target is to have a single node host where I will run Proxmox for all my VM needs, but I also want top have all my storage needs on this server a swell. I am running an oldish SuperMicro 846 with 24 hot plug bay hardware, dual AMD hexacore opteron and 48GB ram

Proxmox is setup on 2 x 120GB SSDs in ZFS Mirror mode (see first code block)
all default.

I have created my data storage pools using my 2TB and 3TB disks (tank0 and tank1 respectively)

as proxmox configures by default,
in "Datacenter/Storage" I have
local === Directory ==== Container template, ISO image, VZDump backup file
local-zfs === ZFS ==== Disk image, Container

My Questions are :


#1. can I / should I additional storage to the main system pool?
I have 2x 1TB HDD so I can make a 1TB mirrored vdev to use. speed is not an issue but having an extra space would be nice as main rpool is only 100GB

#2. what would be the best way to share the space on tank0 and tank1 to the outside?
my plan was/is to setup a FileServer VM and add the tanks to it than manage all the sharing and other things from there. would not mind some help on what would be the best way to do this.

I really like the TurnKey File server container available in Proxmox but how would I go about plug the tank0 and 1 into to so I can manage shares and space propelry?

thanks. Vl

#1. can I / should I additional storage to the main system pool?

I personally would avoid mix SSD with HDD.
Technical it is working but the speed are given by the slow HDD.
Also mixing disk with such huge size difference are not recommended.

But what you can do is install the rpool on the 2 1TB disks.

#2. what would be the best way to share the space on tank0 and tank1 to the outside?

NFS or SMB are supported by zfs.
There are may HowTo which describe this setup.

Alternative you can make a big single disk which is used by a VM like OpenMediaVault.
Or passthrough the disk to the VM and handle the disk direct in the VM.

well, I really do not want to mix anything. I do not want to add the 1TB to the rpool,
I was thinking if I could say create an additional pool, say "pvstore", and add it as a local storage in the data center tab.
so the node can use it but the main boot pool is clean and not slowdown much.

I am still reading up on Proxmox and zfs use, but so far have not found much useful info that would help in my setup, as in help with what I want/thinking to do here. maybe some one will point me into right direction.

thanks, VL

Yes for sure.

thanks.
I did the setup and it works fine.
I also figured out the sharing of tank0 and tank1 using turnkey FileServer container.
looks very very good.
