I have a crush rule like You still can use device classes! Not peace, full object. If we talk about non-EC pools.* host0 has a piece of data on osd.0 host1 has copy on osd.1 *or* osd.2* host1 has pieces of data on osd.1 and osd.2 host2 also will be have one copy of object.* host2 has no data Also do not forget - hosts
with half of osds of host1 (i.e. host0 and host2) will be do
"double work" in comparison.
You can
minimize this impact via decreasing osd crush weights
for host1.
