Hello All Trying to implement the osd leveldb backend at an existing ceph test cluster. The test cluster was updated from 0.72.1 to 0.80.1. The update was ok. After the update, the "osd objectstore = keyvaluestore-dev" setting was added to ceph.conf. After restarting an osd it gives the following error: 2014-05-22 12:28:06.805290 7f2e7d9de800 -1 KeyValueStore::mount : stale version stamp 3. Please run the KeyValueStore update script before starting the OSD, or set keyvaluestore_update_to to 1 How can the "keyvaluestore_update_to" parameter be set or where can i find the "KeyValueStore update script" Thanks, Geert
