Can't add NFS Remote

runevn

I have a NFS share that I have tried to add as a remote. I can add it and it stays as enabled but with a red warning icon besides and in the log I have the error below.

I'm running the community edition (build from source) of XO (xo-server 5.76.0) and (xo-web 5.78.1). I have two other NFS shares (ISO SR and a NFS SR) on this XO that works fine.

XO is running on a Debian 10 VM with the nfs-common package installed.

Any idea of what cause the error?

Does

showmount -e 192.168.99.1

work?

No messing around with jumbo frames or something?

runevn

@jedimarcus - thanks for your reply. No jumbo frames

[08:00 vmhost ~]# showmount -e 192.168.99.1
Export list for 192.168.99.1:

@jedimarcus maybe I found the error. I ran showmount -e 192.168.99.1
on my XCP-NG host and not on my XO VM. So I guess that this is the issue?

However, NFS server (TrueNAS 192.168.99.1/30) is directly connected (no switch inbetween) to my XCP-NG host (192.168.99.2/30) on eth1.

This might be a stupid question but, how should I add the NIC to my XO VM?

If I add/create eth1 to the XO VM what IP should I assign to it?

Because both XCP-NG and TrueNAS are directly connected. I guess that giving the XO VM the IP of 192.168.99.2 will conflict with XCP-NG's IP? Or are there something that I'm totally missing here? ... there probably is

Once again, thanks for your help I really appreciate it!

A remote is mounted from XO virtual Appliance (XOA), not from your host.

So you need to add an interface in that network, and create a fixed IP that can reach your TrueNas.

@olivierlambert Thanks! I did that and now it is just works.

Thanks for the help!
