Also watch out for the constituent member ( volumes under the covers ) count - I find the "default" is too high sometimes for the solution I am looking for.

Unfortunately there's no hope of me getting to that release any time soon, but do DBs and VMDKs lose performance with FlexGroups? And does it really help on just two node clusters? I would assume it might help on four node clusters on up.

Yes, it helps. Especially for HFC environments, it definitely helps (High file count). Even if the FlexGroup is only on one (1) node, it makes a difference and it can be quite big, it depends on the workload pattern. BTW it's not really advisable to span a FG across more than four (4) nodes over the ClusterNet switches, even if you have a large cluster with >16 nodes
