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...
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)
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?
Thanks,
Hanson

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?

Are the repos configured correctly on the new nodes? Does the oVirt cluster
where the nodes are being added have "Enable Gluster Service" enabled?

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

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

I was referring to oVirt's engine.log. Found under
/var/log/ovirt-engine/engine.log

Ok, in this case - in addition to adding the new nodes to cluster, you will
also need to add bricks to the volume and increase the replica count to 5.
You can do this using the "Add Bricks" from the Bricks tab on selection of
a gluster volume. Ensure that you set the replica count to 5 here. This
should be done once you successfully add the new hosts to the cluster.
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.
This is because the nodes have not been added (or peer probed) to existing
gluster cluster.
I will need the logs I requested to understand why.
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.

Hanson
