Probably because the documentation leaves to many questions unanswered...
You can't tell what's wrong as long as you don't know how it should work.

Example: What's the purpose of /var/lib/corosync/ringid_* files, and why do some hosts have /var/lib/corosync/ringid_127.0.0.1? The file content seems to be some binary number, but the file is created with rwx permissions...

On systems with two rings (not on 127.*) I see all combinations from one to three ringid files.

Ulrich
