I'm not sure which services are colocated in this example inventory. Are the mons and mgrs are colocated here? So osds and rgws run on seperate hosts?

Comment 2 John Brier 2020-06-19 19:33:00 UTC 
The example inventory file that 'jkastning' highlighted is confusing within this context. It doesn't show colocation at all AFAICT:

[mons]
MONITOR_NODE_NAME_1
MONITOR_NODE_NAME_2
MONITOR_NODE_NAME_3

[mgrs]
MONITOR_NODE_NAME_1
MONITOR_NODE_NAME_2
MONITOR_NODE_NAME_3

[osds]
OSD_NODE_NAME_1
OSD_NODE_NAME_2
OSD_NODE_NAME_3

[rgws]
RGW_NODE_NAME_1
RGW_NODE_NAME_2

It should be:

node1,node2,node3...node8

And you should have those nodes spread across the different roles so there is some colocation going on.
