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?
7:57 a.m.
Is 3 the max number of hosts?

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

New subject: Hosted Engine w Gluster - increase number of hosts
I thought the total number of hosts has to be odd (5, 9) not even (6,
8).
I guess I was wrong.

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.

How many host should I
add per best practice.
I have 3 now, do I add 2 or 4 more.
Should the total number of host be odd or even?

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, 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.

Must all 7 hosts have the same amount of storage/number of disks?
3:33 a.m.
Hi,
hosted engine does not care about disks. Gluster might, but I do not
know enough about best practice brick layout there, sorry.

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

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)
