From the roots, Ceph has been designed to grow from a few nodes to several hundreds, and it's supposed to scale on the fly without any downtime. In this recipe, we will dive deep into the Ceph scale-out feature by adding MON, OSD, MDS, and RGW nodes.
Adding an OSD node to the Ceph cluster is an online process. To demonstrate this, we would require a new virtual machine named
ceph-node4 with three disks that will act as OSDs. This new node will then be added to our existing Ceph cluster.
Run the following commands from
ceph-node1 until otherwise specified:
ceph-node4, with three disks (OSD). You can follow the process of creating a new virtual machine with disks and the ...
