Pulse try to get up the interfaces more fast than the driver can handle and some IPs dont get up. Our "solution" was install RedHat but over XenServer, the hypervisor handles the interfaces without problems.

This happens on a start, a restart, relocating to the backup pulse box, relocating back to the master pulse, etc. Following which the alias interfaces that don't come up need to be brought up manually before those balancers work. > > Has anyone seen something like this before? > Logs don't show any failures or warnings, just making sockets available and creating monitors. > > Our balancers all follow a similar configuration template for example: > > virtual balancer-http { > active = 1 > address = XX:XX:XX:01 eth0:5 > vip_nmask = 255.255.255.192 > port = 80 > use_regex = 0 > load_monitor = none > scheduler = wlc > protocol = tcp > timeout = 120 > reentry = 30 > quiesce_server = 0 > server cluster-box1 { > address = XX:XX:XX:02 > active = 1 > weight = 1 > } > server cluster-box2 { > address = XX:XX:XX:03 > active = 1 > weight = 1 > } > server cluster-box3 { > address = XX:XX:XX:04 > active = 0 > weight = 1 > } > } > > > _______________________________________________ > Piranha-list mailing list > Piranha-list@redhat.com > https://www.redhat.com/mailman/listinfo/piranha-list > > -- Carlos Infantes Oanes Unitat d'Actuació en Salut Pública Direcció General de Salut Pública Conselleria de Sanitat - GVA Tel.: 961 925 850 </div> </div> </body> </html>
