Doubts if make NFS sharing for VM data folders

[valepe]

Hi, I'm ready to install Proxmox on a DL380p Gen8 for my homelab.
I searched a bit and I'm oriented to install samba service on the host to share some folders to the network.

One or two of these folders are data/configs of VMs (mainly Docker containers configs).

If I mount these paths to the VMs and the same paths are also shared via Samba will I have file accessibility issues?

Or should I also share these folders via NFS to mount them inside the VMs?

Thanks

i don't completely understand your question,
samba is very similar to nfs, if you share some folder via samba you can mount it over the network in the vms (the same as nfs)

what exactly do you want to share where you think there will be problems?

An example: I have a Docker config folder inside a dataset.
I would like to mount it to the VM that runs Docker for containers purposes.
I would also like to share it to be able to change the configurations of these containers from my PC.
I thinked that it's a better way to avoid the extra layer of Samba share on the VM side.
Is this double access in creating and modifying the files prone to conflicts?

Thanks

i thought you wanted to share it on the host?

if you modify a single file from multiple places simultaniously, yes that can lead to conflict, but that depends on how/when you modify them and not really anything to do with samba/nfs or the like

Yes

I worried about file permissions conflicts

Can you give me some suggestions about that?

I thinked via mountpoints

do you mean bind mounts? but that only works for containers (you only ever wrote vms)

if you meant containers & bind mount, check out https://pve.proxmox.com/wiki/Unprivileged_LXC_containers

otherwise just normal samba configuration, but this is not really a pve relevant topic, more like general sysadmin/linux stuff
