I've created dedicated network for NFS in 3 Proxmox nodes. Created a bridge/switch (vmbr1), assigned an interface (enp5s0), created Linux VLAN configured IP without gateway & Vlan raw device in vmbr2 in it. All of them nodes can ping each others NFS interfaces but not the other network. I'm not able to ping the NFS storage that's on a different VLAN. Need to know, if am I missing anything with my configuration.
Dedicated Proxmox network interface connectivity issue

Hi @AndyKosh ,
It is impossible to draw any conclusions about the behavior of your network without detailed technical information about your environment. This should include network configuration files, the current state of the systems involved, NAS network settings, routing tables, ping outputs, and any other relevant diagnostics.

I've added 8 interfaces enp5s0-enp12s0, connected through Cisco UCS (4 interfaces per uplink switch for redundancy).
Added 4 bridge/switch vmbr0-vmbr3.
1. vmbr0 -> bond0 (enp9s0/enp10s0) -> vmbr0.227 (proxmox mgmt.)
2. vmbr1 -> enp7s0 -> for VM traffic
3. vmbr2 -> bond2 (enp5s0/enp6s0) -> created sub interface NFS and added vmbr2 as raw devise mapping. vlan 1921
4. vmbr3 -> bond3 (enp11s0/enp12s0) -> created sub interface Migration and added vmbr3 as raw devise mapping

@AndyKosh ,
There is a lot going on here, and none of it is related to PVE. This is purely Linux network management.
The output you provided is extremely difficult to read. You must have noticed the ASCII encoding issues in your copy/paste. The forum allows for flexible text formatting using CODE </> tags as one option. In many cases, you can also paste plain text using
In all of the output, you only mentioned that the “NFS storage is on a different VLAN” - different from what? Which VLAN? Why do you believe you should be able to ping or access that VLAN if your hosts' NFS interfaces are on a non-routable subnet? Should this NAS be accessible via the management network (VLAN 227)? Did I miss something? If so, I apologize.
Is this is a business environment? In any case, I strongly recommend stripping everything down to the basics and then rebuilding the configuration layer by layer.
