From: "plysan" <plysab@gmail.com> To: engine-devel@ovirt.org Sent: Wednesday, August 21, 2013 4:49:31 PM Subject: [Engine-devel] Ideas about engine clustering?
Hello, guys:
I'm trying to make a jboss clustering environment for engine. But felt the difficuty too. So I want to know if any one is working on this? I googled it and haven't found anything.
I know there will be lots of things to do for engine migrating to clustering environment. I just want to know what problem need to be solved? I would like to list the things I think that is needed to do(or solve): 1. run jboss in standalone-ha mode or domain mode. 2. add @Clustered annotation to each EJB, I think this will solve the replication problem in cluster, probably lots of details in it. 3. QuartzScheduler problem, only one node running a scheduler is enough at a time instead of each node running one. 4. use mod_cluster to handle load balancing. 5. postgresql clustering. 6. There should be more, but hope anyone can think about it :D
Any ideas?
Depending on your needs/interests, you might want to have a look at ovirt-hosted-engine-setup - allows creating a VM on a host and install an engine on that VM which will also manage the host ovirt-hosted-engine-ha - allows configuring two such hosts for high availability of the engine VM (in the VM level, not application level which is what you discussed above). Both are work-in-progress and are partially usable. Not ready for production, though.
