Hi,
I had a very strange incident some weeks ago.
We are on 9.7 branch.
In one of our vServers, where we had NFSv4 and 4.1 enabled, clients with NFSv4.1 and pNFS where unable to read or write data. Directory listing was possible.
On the vServer, we have several different Vlans and each Vlans has an interface for each node there. Our storage network is completely switched, so no routing between Vlans possible.
After creating a NetApp case, they told me, that pNFS doesn't handle Vlans and the client will get any IP on that node, even when the IP is from a different Vlan and therefor not accessible from the client.
Is this really the case? Is the pNFS process really not Vlan aware and sends any IP from that node where volume is located, even when the IP is in a different network than the client IP?
As suggested from NetApp, I have disabled pNFS and now everything is working.
What is your experience here? Is anybody using pNFS with NetApp and if yes, do you only have one network in your vServer or is the client able to access all IPs there through different Vlans?
I'm curious about your answers.
Best regards Florian Schmid
