Block devices – RBD RBD, aka RADOS Block Device, as you might guess from the name, allows you to allocate space from Ceph and present it to clients as block devices (disks). First, using the ceph-admin machine, let’s check again the cluster is in a correct status: Remember, HEALTH_OK is the desired statu For more information, see Map and mount a Ceph Block Device on Linux using the command line in the Red Hat Ceph Storage Block Device Guide. g. csi. client. Identify kernel versions running on those hosts and compare them to vendor advisories for CVE‑2026‑22992. admin. In the previous chapter, the final result of the activities I’ve done was to have a working Ceph cluster, but in order to be used as a mounted volume, we first need to create an RBD (RADOS block device) in the cluster. org) Directly on a VM (map + mount an RBD image), or Through Kubernetes using the Ceph CSI RBD driver (rbd.
