I'm guessing that's it.  Instead of running the Sernet initscripts (or
systemd thingies), some other initscript is being run and it is
probably not making smbd use the correct configuration, so smbd is
probably running without clustering configured...

... but that's obviously just speculation!  I don't know anything about
the Sernet packages...

Possibly time to talk to someone at Sernet?

peace & happiness,
