Re: Use 2 osds to create cluster but health check display "active+degraded"

[Mark Kirkwood <mark.kirkwood@xxxxxxxxxxxxxxx>]

Righty, both osd are on the same host, so you will need to amend the 
default crush rule. It will look something like:

rule replicated_ruleset {
        ruleset 0
        type replicated
        min_size 1
        max_size 10
        step take default
        step chooseleaf firstn 0 type host   <=== ah! host!
        step emit

So you will need to change host to osd.

See http://ceph.com/docs/master/rados/operations/crush-map/ for a 
discussion of what/how on this front!
