I have two OSD and Mon nodes.
I'm going to add third osd and mon on this cluster but before I want to
fix this error:

You've just created your cluster.
With the standard CRUSH rules you need one OSD on three different hosts for an active+clean cluster.
With this parameters:
```
# cat /etc/ceph/ceph.conf
[global]
mon initial members = ceph-rbx-1,ceph-rbx-2
cluster network = 172.29.20.0/24
mon host = 172.29.20.10,172.29.20.11
osd_pool_default_size = 2
osd_pool_default_min_size = 1
public network = 172.29.20.0/24
max open files = 131072
fsid = ....
[client.libvirt]
admin socket = /var/run/ceph/$cluster-$type.$id.$pid.$cctid.asok # must be writable by QEMU and allowed by SELinux or AppArmor
log file = /var/log/ceph/qemu-guest-$pid.log # must be writable by QEMU and allowed by SELinux or AppArmor
[osd]
osd mkfs options xfs = -f -i size=2048
osd mkfs type = xfs
osd journal size = 5120
osd mount options xfs = noatime,largeio,inode64,swalloc
```
