We're moving from using a single (eth0) interface on our execute nodes
to using a bond interface (bond0) for resilience.
And what we're seeing on those nodes which have been upgraded is:
--
[0,1,1][btl_tcp_component.c:349:mca_btl_tcp_component_create_instances]
invalid interface "eth0"
--
This of course, is because all nodes share a common copy of
openmpi-mca-params.conf .. in which its says:
--
btl_tcp_if_include=eth0
--
So .. does anybody have a suggestion for a way around this during our
migration/upgrade period?
If we place "bond0" in there as well, then we get error messages about
whichever one is absent on the node where execution is happening.
Regards ..
