[Pacemaker] Ubuntu 12.04.2 IP-cluster problem

[Longina Przybyszewska]

Hi ,

I can not make  ‘ mount’ command on active node using   IP-cluster 
addresse  - mount  still uses  real IP addresse the node got at 
installation .

That breaks the access to external NFS storage from the active node.


All resources (drbd/fs/Ip-cluster/lsb-script) start successfully, the node 
gets Ip alias eth0:ha with IP-cluster addresse.

I can use  IP-cluster from external systems (ssh, accessing web), but if I 
would mount filesystem  exported to IP-cluster addresse, I get permission 
denied, because ‘mount’ presents itself with the old IP.



I am really stack on that problem.



It seems that the kernel flush-route  has no effect on ‘mount’ 
command.

Any ideas, how to fix it?
