You need to change the CRUSH map to select osd instead of host.

this is what it shows.
does it mean I need to add up to 3 osds? I just use the
default setup.
If you went with the defaults then your pool size will be 3,
meaning it
needs 3 copies of the data (replica 3) to be valid - as you only
have
two nodes/osd's that can never happen :)
Your options are:
- Add another node and osd.
or
- reduce the size to 2.(ceph osd set <poolname> size 2)
