(Part 1/3 – Installation – Part 2/3 – troubleshooting) This part of the tutorial describes how to setup a simple Ceph client using librados (for C++). The only information that the client requires for the cephx authentication is Endpoint of the monitor node Keyring containing the pre-shared secret (we will use the admin keyring) Install librados APIs On Ubuntu, […]
(Part 1/3 – Installation – Part 3/3 – librados client) It is quite common that after the initial installation, the Ceph cluster reports health warnings. Before using the cluster for storage (e.g., allow clients to access it), a HEALTH_OK state should be reached: cluster-admin@ceph-mon0:~/ceph-cluster$ ceph health HEALTH_OK This part of the tutorial provides some troubleshooting hints that I […]
Ceph is one of the most interesting distributed storage systems available, with a very active development and a complete set of features that make it a valuable candidate for cloud storage services. This tutorial goes through the required steps (and some related troubleshooting), required to setup a Ceph cluster and access it with a simple client […]
