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.
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)
