Hi, I'm just starting to play around with Ceph, so please excuse my
complete lack of a clue if this question is covered somewhere, but I
have been unable to find an answer.
I have a single machine running Ceph which was set up with osd crush
chooseleaf type = 0 in /etc/ceph/ceph.conf, now I've added a new machine
with some new OSDs, so I'd like to change to osd crush chooseleaf type =
1 and have Ceph re-balance the replicas.
How do I do that?
Preferably I'd like to make the change without making the cluster
unavailable.
So far I've edited the config file and tried restarting daemons,
including rebooting the entire OS, but I still see PGs that live only on
one host.
I've read the config docuemntation page but it doesn't mention what to
do to make that specific config change take effect:
http://docs.ceph.com/docs/master/rados/configuration/ceph-conf/
I've barked up the crushmap tree a bit, but I did not see how "osd crush
chooseleaf type" relates to that in any way.
