Hosted Engine w Gluster - increase number of hosts
Using this as reference: https://www.ovirt.org/blog/2018/02/up-and-running-with-ovirt-4-2-and-gluster... Assuming you want to increase the number of hosts from 3 to 5 or 9. How do you add more hosts? What is best practice & any gotcha's?
Is 3 the max number of hosts? On 2018-05-20 22:45, ovirt@fateknollogee.com wrote:

afaik you should have at minimum 3 hosts. Above that you can have any amount you want but I believe you need to have multiples of 3 gluster bricks On Mon, May 21, 2018 at 10:57 AM, <ovirt@fateknollogee.com> wrote:

I thought the total number of hosts has to be odd (5, 9) not even (6, 8). I guess I was wrong. On 2018-05-21 07:09, Jayme wrote:

Still looking for answers? What's the proper process to add more hosts using the Cockpit hosted engine wizard?

Additional hosts should be directly added from the engine.

Hi, we recommend up to 7 HE hosts, it is not important if the number is odd or even. The real implementation limit is much higher and you won't reach it. But since we do not test more than 7 as part of the QE process, we can't recommend it. Best regards Martin Sivak On Wed, May 23, 2018 at 9:43 AM, femi adegoke <ovirt@fateknollogee.com> wrote:

Martin, thank you. 7 is perfect, since my 2 SuperMicro servers are 4-node 2U server's. I am using nodes, so, I will add 4 HE nodes. This is all for testing, no production.
That’s good to know. -----Original Message----- From: Martin Sivak [mailto:msivak@redhat.com] Sent: Wednesday, May 23, 2018 12:58 AM To: femi adegoke <ovirt@fateknollogee.com> Cc: users <users@ovirt.org> Subject: [ovirt-users] Re: Hosted Engine w Gluster - increase number of hosts Hi, we recommend up to 7 HE hosts, it is not important if the number is odd or even.

Must all 7 hosts have the same amount of storage/number of disks?
Hi, hosted engine does not care about disks. Gluster might, but I do not know enough about best practice brick layout there, sorry. Martin On Wed, May 23, 2018 at 11:44 AM, femi adegoke <ovirt@fateknollogee.com> wrote:

If I increase the number of hosts from 3 to 3+n, what is the proper way to add gluster volumes (data/engine/vmstore) to the new hosts? I would like the new hosts to also be hyperconverged (aka compute + storage)
I'm still hoping someone might have an answer to my June 1st question? (see previous post)

You can create new replica 3 or replica 2 + arbiter volumes - so you would need 3 new bricks. The bricks need to be of same configuratation and size, except for the arbiter bricks. To add hosts to existing cluster, you can add hosts via oVirt engine and use the web UI to create bricks and add new volumes. With 4.2, we also provide a way to scale hosts via the Cockpit UI ( from the Manage Gluster plugin on the HE dashboard)
I would like the new hosts to also be hyperconverged (aka compute + storage) _______________________________________________ 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/communit y/about/community-guidelines/ List Archives: https://lists.ovirt.org/archiv es/list/users@ovirt.org/message/BPO65GGXIFZ3SBJZJR4UXPMEAYRWUXZB/
