Hello,
I'm currently switching to Heartbeat (3.0.3) and Pacemaker (1.0.9.1) on
Debian Squeeze with CRM/CIB setup.
This is the first time i try to configure it so please be kind with a
newbie. :)
I would like to setup an active/active cluster with 2 nodes, with sticky
resources and a connectivity check.
At this time i have a basic working solution without connectivity check.
The configuration follows at the bottom of the email.
But i am unable to configure the connectivity check with the pingd resource.
The (basic) configuration explained :
- on node p01 there are 2 sticky resources called WWW1 (apache web
server) and VIP1 (virtual IP)
- on node p17 there is 1 sticky resource called VIP2 (virtual IP)
In my mind this is how it should work :
- if a node is down its sticky resources go to the other node (this works)
- if a node has no connectivity the resources go to the other node
(unable to make it work)
- if a down node goes up, the sticky resources are migrated back on it
(this works in the current setup with no connectivity check)
I created a pingd primitive and cloned it as explained in tutorials and
tried some rules but with no success.
I tried to add the following rules with no success :
location www1-on-p01-connected WWW1 \
rule $id="www1-on-p01-connected-rule" pingd: defined pingd \
rule $id="www1-on-p01-connected-rule-0" -1000: not_defined pingd or
pingd lte 0 \
rule $id="www1-on-p01-connected-rule-1" 1000: #uname eq p01
location vip2-on-p17-connected VIP2 \
rule $id="vip2-on-p17-connected-rule" pingd: defined pingd \
rule $id="vip2-on-p17-connected-rule-0" -1000: not_defined pingd or
pingd lte 0 \
rule $id="vip2-on-p17-connected-rule-1" 1000: #uname eq p17
This is the current setup without active connectivity check but with
cloned pingd primitive :
node $id="52dadc12-ada6-46a0-8474-639a62dfa3ad" p17
node $id="6d96beed-abd9-4ad1-9a92-b6560abc0475" p01

Any ideas about how to make it work ?
