Huh? it sounds like your DNS lookup for `sf3' gave the ip-address of
server sf2.

In any case, did you run the createvol_rep scripts on the scm? You might
be able to replace the VSGDB entries with ip-addresses of the server to
avoid broken DNS lookups, I'm not sure if that works but I guess it
beats debugging your DNS setup.

Purging these bad volumes might be difficult, you'll probably have to
use `volutil purge <volname> <volid>' on sf2 and strip the related lines
out of the VRList.

No relation, these VSGDB addresses actually originate from the era that
Coda still supported multicast ip, E0000104 is The code still
seems to be there, but it is probably broken.
