After an sm change (i.e. using the "-r" switch), nodes can't ping each
other over IPoIB (other protocols also can't communicate).
Is it absolutely necessary to run with the "-r" switch? Here we have not
problems letting the SM attempt to use the same LID's for nodes.
yes, especially when chaging routing algorithms between the default
and fat-tree.
As Yevgeny said it looks like an error (or at least unexpected behavior)
in fat-tree code. Could you send ibnetdiscover output and "old" guid2lid
file for us?
There's also an open bug on bugzilla for this:
https://bugs.openfabrics.org/show_bug.cgi?id=1031
(which also lacks the details that would help me to reproduce it).
