RHCS 3- DataNodes configuration with different labels using ansible
Current ansible version,
[root@mon1-ceph-eaa .ssh]# rpm -qa|grep -i ansible
ceph-ansible-3.0.33-1.el7cp.noarch
ansible-2.4.4.0-1.el7ae.noarch
[root@mon1-ceph-eaa .ssh]#
As shown below the disk label is different on different data nodes -
Below on DN11 - the first OSD disk label is 'sdc' and for DN13 its 'sdb'
Note: MB6000GVYZB --> are SATA disks used for OSD's
MO000800JWFWP --> SSD disks used for hosting the OSD journals

Given the different disk configuration, how to define the osds.yml to consider the OSD and SSD configuration.
We have already created a cluster, how can we edit the osds.yml and consider new datanode addition with different labels withour impacting the current cluster status.
