I was planning on making a Gluster Data domain to test, and found some grea=
t information on this page: http://community.redhat.com/blog/2014/05/ovirt-=
3-4-glusterized/
The article the author uses the CTDB service for VIP failover. Is it possi=
ble/recommended to not do this, and just create a gluster volume on all the=
hosts in a cluster, then create the Gluster data domain as localhost:<glus=
ter_vol>?
Thanks,
Ryan

Theoretically, it should work - if you make sure that you have a replica
3 gluster volume spread across 3 nodes, and these 3 nodes are your
compute nodes as well - you should be fine without CTDB setup for
failover and mounting as localhost.
But I've not tried this to recommend it. Maybe if others have tried it,
they can chime in?
Btw, is there any reason you do not want to set up CTDB?

Nope in fact I followed the guide and found CTDB works quite well. I am ju=

I have two nodes running the hosted engine and gluster setup for replicate
between them. Mounting to localhost seems to be working so far. I have live
migrated the engine, pulled the plug on a running node, and rebooted each
node to ensure it all works properly. I have had few issues with this setup.
I didn't like ctdb because it adds another layer of complexity that is
unnecessary for MY setup.
Node1 gluster drive on sdb
Node2 gluster drive on sdb
Both replicate and are the same make and model drive.
ovirt-ha running on both for hosted-engine
This setup is for hosted engine only, my actual storage for VM's and what
not do not run in this fashion.
Hope This helps

I have setup an environment with 8 glustefs nodes in
distributed+replicated mode. Instead of CTDB, I'm using keepalived. It
works pretty well.

Node1 gluster drive on sdb
Node2 gluster drive on sdb
Both replicate and are the same make and model drive.
ovirt-ha running on both for hosted-engine
This setup is for hosted engine only, my actual storage for VMs and
what not do not run in this fashion.
Hope This helps

Theoretically, it should work - if you make sure that you have a
replica 3 gluster volume spread across 3 nodes, and these 3 nodes are
your compute nodes as well - you should be fine without CTDB setup for
failover and mounting as localhost.
But I've not tried this to recommend it. Maybe if others have tried

Btw, is there any reason you do not want to set up CTDB?
Thanks,

But I've not tried this to recommend it. Maybe if others have
tried it, they can chime in?<br>
<br>
Btw, is there any reason you do not want to set up CTDB?<br>

Subject: [ovirt-users] Help understanding Gluster in oVirt
I was planning on making a Gluster Data domain to test, and found some great
information on this page:
http://community.redhat.com/blog/2014/05/ovirt-3-4-glusterized/
The article the author uses the CTDB service for VIP failover. Is it
possible/recommended to not do this, and just create a gluster volume on all
the hosts in a cluster, then create the Gluster data domain as
localhost:<gluster_vol>?
I think that should work -- the vip is important for nfs, and since the hosted
engine requires nfs, I just use the vip for the gluster mount as well.
For 3.6, I believe gluster will be an option for the hosted engine, and so
ctdb will probably not be necessary.
Regards, Jason
Thanks,
Ryan

I am in the process of adding two more nodes to my hosted-engine setup using
localhost as the mount point, I will report how it goes.
I guess it would really be dependent on how the system was setup. Each node
would have to be exactly the same to expect good results.
My major issue with ctdb is SELINUX, I cannot get it to run correctly and
work with SELINUX enabled. I would define that as a major security hole on a
hypervisor, but I'm sure I am just doing it wrong.

Yeah, in my howto I'm using the meta volume that ctdb uses for its lock
file to also store the config files for ctdb, and that's what selinux
doesn't like. It's not really necessary, though, the configs could just
be copied into the default locations on each node -- I think that would
resolve the selinux issue.
