The CTDB docs
(https://wiki.samba.org/index.php/Adding_public_IP_addresses) seem to
suggest you can have multiple IPs per node, i.e. on multiple NICs,
managed by CTDB.
I'd guess that the /etc/ctdb/public_addresses file might look something
This might be a better question to ask in a Samba/CTDB forum. Or perhaps
Günther or Michael can point to some better documentation than what I
was able to find.
