[OSR-users] Problem with rgmanager

[Stefano E. <ste...@so...>]

Hi Mark,

excuse me if I answer only now but I was on vacation.
I am writing to confirm that the problem was that I didn't change the  
file /etc/hosts.......
...... as we say in Italy...... I'm lost in a glass of water !!


Thanks,

Stefano

Stefano,

could you please give us an overview of your network setup ?
# cat /etc/hosts
# ip addr

Could you also send me the output of the following command:
# cman_tool status
# cman_tool nodes

Thanks,

Mark
