Hello all, I've recently come across a problem I've been having, I want to set up network-wide ISO storage so I can make new VMs on other servers in a cluster without having to download the ISO again. Can I do something inside of Proxmox or Ceph to achieve something like this?

Any help is appreciated, Thank you.
 
You could use a NFS/CIFS network share as your ISO storage. But PVE got no NAS functionalities, so you need to setup a NFS/SMB server yourself.

You can run nfs in two ways - kernel or user space. User space is slower.

Which resources do you mean? Storage/CPU/RAM?
For some ISO shares you will not need a lot.

Yeah I meant CPU/RAM if server has limited resources. How much slower is user space? I have only ever used SMB to be honest but I am interested in using or trying NFS if it’s better?
 
1-2G RAM and 1-2 CPUs should be enough.

SMB is for client access like Windows. In the Unix/Linux world you should use NFS.

You need to test the difference between user and kernelspace. I never used user space nfs servers.
