Hi, this post is a follow up to a discussion on this list beginnig of April.
Does anybody did setup a Linux-HA Cluster on a OpenVZ virtual system? I ran into trouble using the IPaddr2 resource. Since a OpenVZ virtual machine is not able to set its own IP address the resource IP for the virtual address of the cluster will always fail. - One solution was to set net_admin capabiliy to that virtual machine. But I did not succeed in trying that. If somebody succeeded, please mail me. - The second suggestion was to setup new virtual devices for the node. See http://wiki.openvz.org/Virtual_Ethernet_device But I think this also will not work, because the underlying host does proxy arp for the virtual ip address. If the ip resource is moved to another node that underlying host will still do proxy arp and advertise the old node. Did anybody find a solution here? - The third way I found was to rewrite the IPaddr2 RA a little bit so that it passes on the information about adding / removing the ip address to the underlying host which in turn does a: vzctl set <veid> --ip_add <ip> Any better solutions? Thank for a fruitful discussion. -- Dr. Michael Schwartzkopff MultiNET Services GmbH Addresse: Bretonischer Ring 7; 85630 Grasbrunn; Germany Tel: +49 - 89 - 45 69 11 0 Fax: +49 - 89 - 45 69 11 21 mob: +49 - 174 - 343 28 75 mail: [EMAIL PROTECTED] web: www.multinet.de Sitz der Gesellschaft: 85630 Grasbrunn Registergericht: Amtsgericht München HRB 114375 Geschäftsführer: Günter Jurgeneit, Hubert Martens --- PGP Fingerprint: F919 3919 FF12 ED5A 2801 DEA6 AA77 57A4 EDD8 979B Skype: misch42 _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
