I believe that you can enable broadcast for heartbeats by changing the following value from multicast to broadcast in /etc/cluster/cluster.conf on all clustered nodes. The CMAN service will need to be restarted on each node as well. Be sure they become quorate again with the following command below.
I was going to knowledge base for your post, and I am planning to use gfs2 filesystem for clustering mysql database. after going through this documentation broadcast mode is not suitable mode for GFS2 ? so what will be alternate mode to configuring filesystem.
Code:
Broadcast mode is not suitable for deployments that require high performance locking. Examples include the following:
GFS/GFS2 deployments that use file locking extensively.
Cmirror usage
Any use of Corosync/OpenAIS outside of Red Hat Enterprise Linux that would require high performance message transport, such as Apache Qpid messaging.
I am not 100% sure what other filesystems would be used for broadcast. What's the reason for not using the multicast method? The switch not allowing it?

Hi everyone. Our professor in Operating Systems gave us a research work about the Heart OS and Love OS. We were told that they were old operating systems from UNIX but I couldn't find any information about them from google. I hope someone here could point me to the right direction. Thanks! (7 Replies)
I just had this idea of using Android (a linux derivative) to monitor heart rates of patients with a history of cardiac problems. There are plenty apps around that monitor heart rates, but none for people that require medical attention when their heart rate drops below a certain level for more... (0 Replies)

We run two p5 nodes running AIX 5L in a cluster mode (HACMP), both the nodes share external disk arrays. Only the primary node can access the shared disks at a given point of time.
We are in the process of adding two new disks to the disk arrays so as to make them available to the existing... (3 Replies)
