10.160.9.1 is the gateway. I can ping gateway.
10.160.90.47 is the dns nameserver. I have also tried manually inserting servers via /etc/hosts fails but this fails.

My hope is that I misconfigured something instead of this being a bug...

Thanks guys.

CTDB does not have following config variables:

CTDB_PUBLIC_NETWORK
CTDB_PUBLIC_GATEWAY

If you want CTDB to manage the default route, you can create a static routes file as follows:

----- /etc/ctdb/static-routes -----
eth1 0.0.0.0/0 10.160.9.1
----- /etc/ctdb/static-routes -----

No further information received.  Assuming this is not a CTDB bug...
