Hi Linux-HA list,
I will try to keep this short, but I could do with your help.
I have a server that runs a company application. The application basically
traces network usage by networked devices. The application does this using MAC
/ IP tracking.
To achieve this it runs on Fedora 8 and requires squid, snmptrapd, internal /
external NICs etc. and now needs to be HA on two nodes.
My problem is I need both servers in my cluster to have the same (everything?)
IP addresses for internal and external interfaces as well as MACs etc.
We want the impression to be 100% uptime in the event of an outage / comms loss.
I read a good article on using the cluster-hash option with IpAddr2, but while
this does allow the "network" think my address say 10.0.0.1 is actually on
01:02:03:04:05:06, the custom iptables script over-writes it when the company
application comes up (which needs good comms before starting).
I am not sure how to get around this, please can (if you understand what I am
trying to do) let me know a few things to try?
Information available upon request :)
I do everything in the gui at the moment.
G.
