Does it strictly follow this?

We were doing some testing with tap interfaces into vxlan networks and found that if we simulated taking down the vxlan interface (which appears in ifconfig as a physical int really), then it moved the ces ip onto the box's primary Nic which was a different subnet.

simple question  -sorry for that - your Nodes.. do they have an IP address in the same subnet as your IP address listed here ?
and if, is this network up n running so that GPFS can find/detect it ?

what tells mmlscluster --ces ?


from each node - assuming class C /24 network , do a
ip a | grep 10.30.22.





cheers

Can anyone help me pinpoint the issue here? These message repeat and the IP addresses never get assigned.
