Faq'n Tips

Hey! This doesn't look like a FAQ! What gives?
-
Every time my machine releases an IP alias, it loses
the whole interface (i.e eth0)! How do I fix this?
-
I want a lot of IP addresses as resources (more than
8). What's the best way?

Quit your bellyachin'! We needed a "catch-all"
document to supply useful information in a way that was easily referenced
and would grow without a lot of work. It's closer to a FAQ than anything
else.

This isn't a problem with heartbeat, but rather
is caused by various versions of net-tools. Upgrade to the most recent
version of net-tools and it will go away. You can test it with ifconfig
manually.
-
Instead of failing over many IP addresses, just fail
over one router address. On your router, do the equivalent of "route
add -net x.x.x.0/24 gw x.x.x.2", where x.x.x.2 is the cluster IP address
controlled by heartbeat. Then, make every address within x.x.x.0/24
that you wish to failover a permanent alias of lo0 on BOTH cluster nodes.
This is done via "ifconfig lo:2 x.x.x.3 netmask 255.255.255.255 -arp" etc....
