[Linux-cluster] local node name "app-acc-006.app.rws.local" not found in cluster.conf



Hello,



I am trying to move my cluster heartbeat to a different (interconnect)
VLAN without changing the hostname.

- Machines 1-5 have set their hostname to app-acc-00[1-5]-ic to
enforce the setting.

- Machine 6 has its regular hostname app-acc-006

- The alternate hostname app-acc-006-ic is registered to the bond1
interface through DNS and /etc/hosts.

- O/S: Red Hat Enterprise Linux Server release 5.3 (Tikanga)

- Cman: 2.0.98



The nodes with the changed hostname work fine; however our
applications expect the regular hostname.
So while this workaround would get our cluster working, it would break
our application.

What more do we need to keep the hostname as app-acc-00*, while using
the IP attached to app-acc-00*-ic as heartbeat channel?
I currently get:
Feb  2 18:10:24 app-acc-006 openais[5174]: [MAIN ] local node name
"app-acc-006.app.rws.local" not found in cluster.conf

info, cannot start

Feb  2 18:10:24 app-acc-006 openais[5174]: [MAIN ] AIS Executive
exiting (reason: could not read the main configuration file).

Details of the configuration are attached.
