Hi Sahina,
On the fourth node, I've found
/var/log/glusterfs/rhev-data-center-mnt-glusterSD-ovirtnode1.core\:_engine.log
... is this the engine.log you're referring to or do you want one from
the hosted engine?
I actually do want to go replica 5. Most VM's it runs are small(1
Core,1gb Ram,8gb HDD) and HA is needed. I'd like a bigger critical
margin than one node failing.
As far as the repos, it's a straight the ovirtnode iso install, I think
it's Node 4.2.0... which is yum updated to 4.2.1.1
When I installed 4.0 I'd installed on top of centos. This round I went
straight with the node os because of simplicity in updating.
I can manually restart gluster from cli, the peer and volume status show
no peers or volumes.
One thing of note, the networking is still as setup from the node
install. I cannot change the networking info from the ovirt
gui/dashboard. The host goes unresponsive and then another host power
cycles it.
Thanks,
Hanson

Hi Guys,
I've a 3 machine pool running gluster with replica 3 and want to
add two more machines.
This would change to a replica 5...
Adding 2 more nodes to cluster will not change it to a replica 5.
replica 3 is a configuration on the gluster volume. I assume you don't
need a replica 5, but just to add more nodes (and possibly new gluster
volumes) to the cluster?
In ovirt 4.0, I'd done everything manually. No problem there.
In ovirt 4.2, I'd used the wizard for the hosted-engine. It looks
like the fourth node has been added to the pool but will not go
active. It complains gluster isn't running (which I've not
manually configured /dev/sdb for gluster). Host install+deploy
fails. Host can go into maintenance w/o issue. (Meaning the host
has been added to the cluster, but isn't operational)
Are the repos configured correctly on the new nodes? Does the oVirt
cluster where the nodes are being added have "Enable Gluster Service"
enabled?
What do I need to do to get the node up and running proper with
gluster syncing properly? Manually restarting gluster, tells me
there's no peers and no volumes.
Do we have a wizard for this too? Or do I need to go find the
setup scripts and configure hosts 4 + 5 manually and run the
deploy again?
The host addition flow should take care of installing gluster.
Can you share the engine log from when the host was added to when it's
reported non-operational?
Thanks,
Hanson
