Hi,
Problem solved by editting crushmap to change the default rule from "
step chooseleaf firstn 0 type host" to "step chooseleaf firstn 0 type osd"
.
Thanks Ashish and Robert, your reply really helps me a lot.
Thanks again.

Hi,
Anyways its not suggested to have a single node, but if you are having and
you must (may be for testing purposes) you can include :
"osd crush chooseleaf type = 0" in global section of ceph.conf and restart
all ceph services, to have all pgs in active+clean state.
Thanks and Regards

It looks like you have one physical node.
If you have a pool with a replication count of 2 (default) I think it wil
try to spread the data across 2 failure domains by default.
My guess is the default crush map will see a node as a single failure
domain by default.
So, edit the crushmap to allow this or add a second node.
Cheers,
Robert van Leeuwen
