Mailing List Archive: Pacemaker memory usage

Hi,

We are trying to introduce clustering to our embedded environment using pacemaker and corosync.
Our environment includes following packages and modules for the initial test:

1. Pacemaker - version 1.1.10

2. Corosync - version 2.3.4

3. Corosync.conf file find it attached to this email thread

4. 2 Nodes in the cluster (master and slave)

5. Test app1 that publishes some sensor data (only Master node publishes, slave node just receives the data)

6. Test app2 that receives the published data and outputs on the screen (only master node outputs the data on the screen)

Our test has been successful and we are able to create a cluster with 2 nodes and everything seems to be working fine. However we observed that pacemaker is consuming approx. 80MB of RAM when both the test applications are alive.

We would like to know if there are any configuration settings or fine tuning that we need to perform to reduce the memory usage. It is very critical to reduce the memory consumption as we are running it in embedded environment.

Thanks,
Santosh Bidaralli

80M is more than I would expect.

One thing I know you can do is lower the IPC buffer size. That can be done in
/etc/sysconfig/pacemaker. Set the PCMK_ipc_buffer to something smaller than
whatever it defaults to.
