So either make sure these pools really have a replication of 2 by deleting
and re-creating them or add a third storage node.
I just executed ceph osd pool set {POOL} size 2 for both pools. Anything
else I need to do? I still don't see any changes to the

Okay. That's unusual. What's the oldest client you need to support,

Read EVERYTHING you can find about crushmap rules.
The quickstart (I think) talks about 3 storage nodes, not OSDs.
Ceph is quite good when it comes to defining failure domains, the default
is to segregate at the storage node level.
What good is a
Alright, I was finally able to get this resolved without adding another node.
As pointed out, even though I had a config variable that defined the default
replicated size at 2, ceph for some reason created the default pools (data,
and metadata) with a value of 3. After digging trough
I'm pulling my hair out with ceph. I am testing things with a 5 server
cluster. I have 3 monitors, and two storage machines each with 4 osd's. I
have started from scratch 4 times now, and can't seem to figure out how to
get a clean status. Ceph health reports:
HEALTH_WARN 34 pgs degraded; 192

I restarted all of the osd's and noticed that ceph shows 2 osd's up even if
the servers are completely powered down: osdmap e95: 8 osds: 2 up, 8 in
Why would that be?

What's the output of ceph osd map?
Your CRUSH map probably isn't trying to segregate properly, with 2
hosts and 4 OSDs each.

So those disks are actually different sizes, in proportion to their
weights? It could be having an impact on this, although it *shouldn't*
be an issue. And your tree looks like it's correct, which leaves me
thinking that something is off about your crush rules.
