IHAC who is using vfilers in non-default ipspaces on the cluster. Simplified configuration is like this:

• node1: vfiler vf1 in ipspace ips1

• node2: ipspace defined but no vfiler uses it

In both cases ipspaces includes single mode vif (I am not sure if it is significant in this problem).

The configuration does not work during takeover of node1 by node2: there is no interface active for partner takeover (because no vfiler is defined in the ipspace ips1). I reproduced this problem on the simulator and found workaround: to create dummy vfiler on the node2 in the ipspace ips1. Is there any more elegant solution? Is it a bug or a feature?

I have found the solution myself. The problem was quite difficult to solve because the difference between erratic and correct configuration is rather subtle. My customer originally planned to make symmetric configuration and he prepared IP setting for the interface in advance. So there was an entry in /etc/rc file (node2):

ifconfig vif1 xxx.xxx.xxx.xxx netmask yyy.yyy.yyy.yyy mtusize 1500 -wins up partner vif1

vif1 belongs to ipspace ips1 but there is no vfiler defined in ips1 on the node2! So the whole sentence cannot be executed INCLUDING partner statement...

The correct /etc/rc entry is the following:

ifconfig vif1 mtusize 1500 -wins up partner vif1

I have tested this config successfully using Data ONTAP Simulator.
