(...) hi, cman gets its config from /etc/cluster/cluster.conf. in the clusternode tag you have the name attribute. cman get the IP address from that name and uses this interface as interface for the cluster configuration. You have name="sv2827". This names resolves to 10.15.28.27 and thus corosync uses bond0 for the communication in the cluster. If you want more interfaces you have to use the altname attribute (tag?) in cluster.conf. Configure a alternative name of the node that resolves into an other IP address. You can do this by adding the new IP / name to the /etc/hosts. If you do not want to use your productive interfaces, just configure a different name in the clusternode tag. Be sure to have a bond device or two single interfaces for redundant communication. -- Mit freundlichen Grüßen, Michael Schwartzkopff -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64, +49 (162) 165 0044 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein
