Because a few Ceph daemons may store a significant amount of data in /var/lib/ceph (notably, the monitors and prometheus), we recommend moving this directory to its own disk, partition, or logical volume so that it does not fill up the root file system. Red Hat Ceph Storage is very well suited for providing fast and scalable object storage and storage for virtualization hosts. One of the main advantages is that Ceph allows horizontal scaling by adding more and more nodes within hours. A scenario where using Ceph is less appropriate is when one needs a distributed, POSIX-compliant filesystem.
