+//Ceph// ist noch nicht reif für den Einsatz in der Produktion!
+//Ceph// ist ein Cluster-Dateisystem mit den Schwerpunkten:
+  - Ausfallsichereheit
+  - skalierbarkeit
+  - Geschwindigkeit
+Es wird empfohlen Ceph zusammen mit [[btrfs]] zu verwenden.

+  v0.17 released
+  We’ve released v0.17.  This is mainly bug fixes and some monitor improvements.  Changes since v0.16 include:
+      * kclient: fix >1 mds mdsmap decoding
+      * kclient: fix mon subscription renewal
+      * osdmap: fix encoding bug (and resulting kclient crash)
+      * msgr: simplified policy, failure model, code
+      * mon: less push, more pull
+      * mon: clients maintain single monitor session, requests and replies are routed by the cluster
+      * mon cluster expansion works (see Monitor cluster expansion)
+      * osd: fix pgid parsing bug (broke restarts on clusters with 10 osds or more)
+  The other change with this release is that the kernel code is no longer bundled with the server code; it lives in a separate git tree.
