If you're using a single varnish server, then when it goes down your sites are down. > How can this issue be addressed? using the CARP with > replication through drbd? There are a number of options. CARP would work, but when you fail over to the second varnish server it will have an empty cache. We use a load balancer in front of a pair of varnish servers, so they are both in service with warm caches at all times. The load balancer handles failover. This is a pretty common configuration. -Ben _______________________________________________ varnish-misc mailing list [email protected] https://www.varnish-cache.org/lists/mailman/listinfo/varnish-misc
