Kubernetes node with several IP addresses failed to mount NFS volume on Isilon
We use CSI plugin for Isilon version 1.3.0.1, it works well when Kubernetes node has single IP. Then we try to separate network on node, one for services and one for storage network. After change, Kubernetes node failed to mount NFS volume. We have checked Isilon client field and found that CSI plugin filled in the node's service IP which cannot communicate to Isilon. Are there any way to configure CSI plugin to filled in node's storage IP ?

Hi @moo_s09,
The trick is to change the X_NODE_IP environment variable for the driver.
You can check a solution from that post : https://storage-chaos.io/dell-csi-isilon-custom-envvars.html
Let me know if you have any question.

Hello,
My team has followed the step in https://storage-chaos.io/dell-csi-isilon-custom-envvars.html
Unfortunately we stuck on
export X_NODE_IP=<%= %x@ip -4 addr show dev ens33 | grep inet@[/inet\s+(\d+(\.\d+){3})/,1] %>
There is an error -> error syntax error near unexpected token `('
Have you ever try it yet ?

Yes I did, where is the error ? This works from me :
kubectl create -f https://gist.githubusercontent.com/coulof/d4260e4e17910bbdefbbecce4286074f/raw/1a57e020b4bef0644515259c5afc2a74cdb8f290/nodeip-configmap.yaml
PS: we can continue the conversation in PM and post the solution here once done.
