Replacing a failed disk in the Ceph cluster

A Ceph cluster can be made up of 10 to several thousand physical disks that provide storage capacity to the cluster. As the number of physical disks increases for your Ceph cluster, the frequency of disk failures also increases. Hence, replacing a failed disk drive might become a repetitive task for a Ceph storage administrator. In this recipe, we will learn about the disk replacement process for a Ceph cluster.

How to do it…

  1. Let's verify cluster health; since this cluster does not have any failed disk status, it would be HEALTH_OK:
    # ceph status
