Re: Expand existing gluster storage in ovirt 4.2/4.3

You can have hyperconverged setup, but the number of bricks should be multiplied by 3. Best Regards, Strahil NikolovOn Apr 11, 2019 14:52, adrianquintero@gmail.com wrote:
Thank you for the explanation, so from my understanding we can't have a hyperconverged setup if more that 3 nodes are required? or is it possible if gluster is setup separate of the oVirt node installs? _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/77URQGHY7LBF4H...

Hi Strahil, I had a 3 node Hyperconverged setup and added 3 new nodes to the cluster for a total of 6 servers. I am now taking advantage of more compute power, however the gluster storage part is what gets me. Current Hyperconverged setup: - host1.mydomain.com Bricks: engine data1 vmstore1 - host2.mydomain.com Bricks: engine data1 vmstore1 - host3.mydomain.com Bricks: engine data1 vmstore1 - host4.mydomain.com Bricks: - host5.mydomain.com Bricks: - host6.mydomain.com Bricks: As you can see from the above, the original first 3 servers are the only ones that contain the gluster storage bricks, so storage redundancy is not set across all 6 nodes. I think it is a lack of understanding from my end on how ovirt and gluster integrate with one another so have a few questions: How would I go about achieving storage redundancy across all nodes? Do I need to configure gluster volumes manually through the OS CLI? If I configure the fail storage scenario manually will oVirt know about it? Again I know that the bricks must be added in sets of 3 and per the first 3 nodes my gluster setup looks like this (all done by hyperconverged seup in ovirt): engine volume: host1:brick1, host2:brick1, host3:brick1 data1 volume: host1:brick2, host2:brick2, host3:brick2 vmstore1 volume: host1:brick3, host2:brick3, host3:brick3 So after adding the 3 new servers I dont know if I need to do something similar to the example in https://medium.com/@tumballi/scale-your-gluster-cluster-1-node-at-a-time-62d..., if I do a similar change will oVirt know about it? will it be able to handle it as hyperconverged? As I mentioned before I normally see 3 node hyperconverged setup examples with gluster but have not found one for 6, 9 or 12 node cluster. Thanks again.
