Hi Yevgeny,
Is it possible that OpenSM's fat tree routing somehow depends on the
LIDs previously assigned ?
It depends only on the existence of the LIDs.
It seems that for a legitimate fat tree topology, the topology sometimes
won't come up as a fat tree if reassigning LIDs (-r) is not used.
That's odd...
In addition to -r making fat tree work, certain routing algorithms seem
to also clear this out (without using -r). For example, if lash were run
and then ftree, it seems to work without doing the -r. (Haven't yet
tried updn).
Any ideas on this ? Should a bug be filed on this ? Thanks.
No ideas whatsoever. Please file a bug on this.
I filed this as bug 1031:

Thanks
It would be nice if I could reproduce it in simulation.
Yes, that would be nice; but I don't have a sim case.
The problem is, I don't even know where to start.
I tested it in simulations on different topologies,
and it is used on real cluster(s) too.
I need more details, and some hint on how to reproduce it.
Can you describe the setup you used when you saw this problem?
