[SOLVED] NFS network configuration

[AndyKosh]

I want to create a dedicated network for NFS in my 3 node cluster. Need to know the steps to configure it.

Of cause there are multiple ways to set this up and there are definitely more details than would fit into one post. One possible quick-n-dirty approach:

• take a new unused switch (or use VLANs)
• connect one NIC on each PVE node here
• connect the NFS server here
• configure a new bridge with that new NIC on each node. (Using the NIC w/o a bridge is absolutely possible, but this opens more future use cases.)
• test connectivity
• go to Datacenter --> Storage --> Add NFS

Does this sound to fit your needs?

Thanks, I'll try this solution. I've another question again with NFS, while adding NFS through datacenter, which IP does datacenter use to connect with NFS server? is it the HA master node IP address?

which IP does datacenter use to connect with NFS server? is it the HA master node IP address?

There is no dedicated "master" as all nodes are equal. (When you look under "Datacenter --> HA Status" you can notice that the shown "master" node will vary, depending on the current availability.)

Shared storage must be reachable/usable on each and every node¹. Every node uses its own IP address to connect to the NFS server.

Which one is it? Well, if the node has an interface in the network of the NFS server it uses the IP address of that NIC, of course. If not: it is just tcp/ip, so the network of the default gateway will determine the source ip address for this connection.

¹ you can limit the list of nodes to those which can actually do that, but that is not the topic here.

Thanks for the quick reply. I'll close this thread as resolved.
