With the deployment of Lustre 2.5 center wide at ORNL we encountered problems being up the production system due to avoid_sym_router_failure
being enabled by default. The LNET fabric would fail to come up when enabled. Once it was turned off by default everything returned to normal. This would a useful feature at have for this scale of a system. This problem can be easily reproduced at smaller scale in both non-FGR and FGR set ups.
