Hi, everyone.
I'm a newbie about ceph and trying to do some test to understand the behavior
of ceph. The following situation really overwhelmed me:
I first killed a osd, which made the size of the acting set of some pg became
1. Then I set min_size from 1 to 2, after which I started the killed osd. Then
there came the phenomenon that all the pg previous assigned to the killed osd
goes "incomplete". My cluster contains only 2 hosts, each running 10 osds. And
I made the configurations that replicas of pgs be assigned to both osds.
Is it supposed to be this way? What is the philosophy about this?
Thank you:-)
