Description of problem: After upgrading from RHEL6.6 ceph 1.2.3 to RHEL 7.2 and ceph from 1.2.3 to 1.3.2 diamond service might fail to start. so check whether old /var/lock/subsys/diamond lock file exists on the corresponding node and delete the lock file and restart the diamond service in order to get the calamari host graphs. This needs to be documented .
Bara, This step should happen on the cluster nodes connected to calamari. It would be great to have in right here and the next step. " On nodes that were previously connected to Calamari and that you identified in step 7, perform the following steps: Remove the old salt-master public key: and that you identified in step 7 # rm /etc/salt/pki/minion/minion_master.pub"
Now doc has below mentioned info , hence marking it as verified Check if the old /var/lock/subsys/diamond lock file exists and if so, delete the file and restart the diamond service: # rm /var/lock/subsys/diamond # systemctl restart diamond.service
