Betreff: [ovirt-users] Re: multiple engines (active passive)
real HA is complicated, no way around that...
As stated earlier, we also run engine bare metal using pacemaker / corosync /
drbd to keep both nodes in perfect sync, failover happens in a few seconds. We
also do daily backups

years or so that we have been running
Well, I really love oVirt, but I don't know.. All the solutions mentioned
here are complicated and or dangerous. Including hosted ha engine that
fails while deploying(for me). I think that test the backup for recovery is
very important and need to be done on a regular basis, What good is a
backup
I'm still sort of new to ovirt, but I went through a similar things. I had my
original engine fail and had to recover, so here is my "oVirt HA plan"
1. I do NOT use hosted ovirt, I had issues getting it deployed correctly, and
that doesn't help if they engine VM itself has issues. My engine

For what it's worth we do active passive with pacemaker, corosync, and drbd. all the configuration files stay synced by drbd, pacemaker ensures the services are only running on one node. Works pretty well.On Jan 13, 2019 2:33 PM, maoz zadok wrote:is it good enough to disable the ovirt-engine
is it good enough to disable the ovirt-engine "systemctl disable
ovirt-engine" on the standby node?
if it does, what about the other services, do I have to disable the
following as well? :
*ovirt-engine-dwhd.service enabled *
*ovirt-engine.service

Most people that need HA engine use ovirt-hosted-engine,
HA hosted-engine cannot help if VM image are broken. HA runs same image
on different nodes, and if current running VM corrupt FS, for example,
it cannot run on other nodes also.
