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.
Replacing a failed disk in the Ceph cluster
How to do it...
These steps will walk you through the proper replacement process of a Ceph OSD:
- Let's verify cluster health; since this cluster does not have any failed disk status, it would be HEALTH_OK:
# ceph status
- Since we are demonstrating this exercise on...
