Hi all, I am running squid integrated with squidguard.dansguardian,clamav running on single standalone centos 5 server.Also running webmin for managing squid.This Squid is serving for 4000 clients. Since it is serving more users i don't want to take risk by running single server,if there is any single point of failure will cause all of my users to standstill. So i am planned to go for one more Centos5 server with cluster.Can any one suggest me how to design it either i have to go for common storage for storing all global files or i need to synchronize both the server periodically by running instance on local disk of both the servers. Below is the scenario currently running on the server squid is under /etc and squidguard database under /var/lib and dansguardian config file under /etc/dansguardian and webmin is under /usr/local Help me in designing the setup of high availability squid Regards, lingu
