Hi All! 1st of all thanks in advance. If my running Ceph cluster is Centos6.5 with Ceph-firefly v80.1, will a calamari server running on Ubuntu12.04 able to connect/monitor/manage this cluster? I would think Ubuntu base agents have to be installed on the storage-nodes in order for calamari server to collect, store and process data. Or does the running Ceph cluster have to be ubuntu12.04 OS base also? Or since my running Ceph cluster is Centos6.5, I would need to build a Centos6.5 Calamari Server? Or since my running Ceph cluster is Centos6.5, I can build a RHEL6.5 Calamari Server? Or I need to build a RHEL6.5 Ceph cluster and build a RHEL6.5 Calamari Server? Regards, _Ben
