Dear All,
I try to setup a HA firewall, still without real success.
I guess, I have to use pingd, the check, the connection is alive or not.
1.
I've made an example pingd resource with a host, which impossible to
ping and I see, the resource is still running? Why? How should it be
used? What could I make wrong?
The hosts are defined at ha.cf, example:
ping_group ping_nodes IP1 IP2
2. How can I tell to heartbeat, if any of the connection is not alive
(pingd fail), take all resources to the other node, so how all
resource (or just one, doesn't matter I guess) could depend on pingd.
I read http://www.linux-ha.org/pingd, but doesn't understand
everything, I mean, it's a bit too complicated for a beginner on this
subject:)
To move resources because network is down, you need to define a
constraint. Example:
<rsc_location id="my_resource:loc" rsc="resource_name">
<rule id="my_resource:connected:rule" score="-INFINITY"
boolean_op="or">
<expression id="my_resource:connected:expr:undefined"
attribute="pingd" operation="not_defined"/>
<expression id="my_resource:connected:expr:zero"
attribute="pingd" operation="lte" value="0"/>
</rule>
</rsc_location>
To use pingd you need to define a clone of pingd. All instructions is
for a V2 Heartbeat cluster mode.
Thank you,
tamas
