Iirc you need to have multiples of three severs for hyperconverged. You
could have a 4 server cluster but only three of them would be participating
in storage and one would be compute only. Someone correct me if I’m wrong.

Hey folks!
Quick question, really: I have 4 servers of identical hardware. The
documentation says "you need 3", not "you need 3 or more"; is it
possible
to run hyperconverged with 4 servers (in same rack, let's neglect the
possibility of 2 failing servers (split brain))?
Also: I have a nice seperate server (low power footprint, big on cpu (8)
and has 32gb ram)-- would love to use this as engine server only. Can I
initiate a hyperconverged system with 4 working host starting from a
stand-alone engine? Or does "hyperconverged" a must for HA engine on the
cluster?
One last one: Installing ovirt nodes, obviously. This will by default
create a lvm across the entire RAID volume; can I simply create folders
(with correct permissions) and use those as gluster bricks? Or do I need to
partition the RAID in a special way?
Thanks for your pointers,
Chris.
