Hey Guys,
Could you confirm what would be the scenario for Squid working in HA ?.,
That depends on your setup ... we have squid running in a resource group
with winbind (for authorization against AD), the respective internal
gateway IP, and pingd resources that monitor external access and DNS
resolution. If one of these resources fails to run or the internet/DNS
is not reachable, the whole group will migrate to the second server.
Setups are identical otherwise, we synchronize configuration files of
squid etc via separate methodds (rsync via ssh), so we do not need to
use a distributed filesystem for this. This is a version 1 heartbeat
setup; we are currently experimenting with pacemaker and corosync but
are still struggling to put everything together on a CentOS 5.5 box.
HTH,
Jakob Curdes
