Proxmox cannot find my NAS through NFS

[zinogr3]

I've followed the official Synology's Proxmox Storage via NFS for backup purpose, but "the volume path" with my NAS IP Address never show up. I know there are many possible culprits, so here what I know.

Proxmox VE cannot ping to my NAS or PC, even though I can reach it's GUI just fine.

Proxmox machine is connected to a switch via an ethernet cable. And I believed I had configured the VLAN correctly, because all I have to do was just create a new VLAN with untagged router, while tagged the NAS & Proxmox machine.

Synology's NFSv4 is enabled, because v3 is not supported.

There is no firewall in my router that block any port.

In the Synology NAS's Shared Folder, the target folder's (which got all users permitted) NFS Permission are:

Hostname: 192... (correct Proxmox static IP Address)

Privilege: Read/Write

Squash: No mapping (and I even tested with "Map all users to admin")

Security: sys

Enable asynchronous

Enable allow connections between non-privilege ports

Enable allow users to access mounted sub-folders

I'm not sure what I am missing here. I know there are other options like running PBS in a VM or bare metal, but I would like to try this "supposed" simple method first.

Hi zingr3,

Do I understand correctly:

+ you CAN ping your PVE-host from your PC.
+ you CAN ping your PVE-host from your Synology NAS.
+ you CANNOT ping your PC from your PVE-host.
+ you CANNOT ping your Synology NAS from your PVE-host.

A few questions:

+ Can you ping something like google.com from your PVE-host?
+ Can you run `apt update` on your PVE-host?

How are you using VLANs in your network? Is trying (for debugging) without separate VLANs an option for your setup?

Best regards,
Daniel

Yes

+ you CAN ping your PVE-host from your Synology NAS.

No. I done this by accessing my NAS through ssh. (I think it is the only way.)

+ you CANNOT ping your PC from your PVE-host.

Yes

Yes

Yes

+ Can you run `apt update` on your PVE-host?

No

How are you using VLANs in your network?

Each vlan always untagged to my router, but not necessary tagged to each node. So, as expected, NAS vlan 10, and PVE vlan 20 cannot ping to each other.

Is trying (for debugging) without separate VLANs an option for your setup?

If you mean putting NAS & PVE into the same vlan group, yes, I can do that. However, the result is the same as above.

_______________________________________

If I did not assign any vlan to my NAS & PVE (defaulted to 1), then they can ping to each other, but this isn't the setup I want with my network.

@zinogr3

The command to update PVE seem to be apt full-upgrade.

but this isn't the setup I want with my network.

Although this is what I would prefer, but I really want the backup. So, no more VLAN, and all the nodes can be ping to each other now. However, the PVE's NFS still cannot find my NAS.

Another big changes I done is I went with installing a PBS LXC in the same PVE machine; and I done all the necessary PBS configuration (I think). The lingering NFS problem remained. I feel like I am forgetting something.

Solved! In the shared folder NFS, the IP Address must be PVE. Not PBS.

However, I encountered another technical problems. Let see if I can solve it by myself before asking for help again.
