This may be a silly question....   But when setting up a node/cluster using the GUI, where do you specify the topology?   Using the default settings ends up creating an error "No Nodes in Volume Topology"   What's the root cause and how do you avoid this?   IMHO simple installs should result in simple systems without any inherent errors.

Posting here since it won't let me message Community Manager when we're not "connected" .   I've seen this happen a few times in the past.  The last few days points haven't been rewarded by the forum for doing normal things (e.g. getting an answer, comments/help marks/etc).  Some process is probably down.   Not a big deal but just FYI.
