I noticed ceph added key/value store OSD backend feature in firefly, but i can hardly get any documentation about how to use it. At last I found that i can add a line in ceph.conf: osd objectstore = keyvaluestore-dev but got failed with ceph-deploy creating OSDs. According to the log, ceph-disk still tried to part a journal partition but failed. The commands i used are: ceph-deploy disk zap CVM-0-11:/dev/hioa ceph-deploy osd prepare CVM-0-11:/dev/hioa ceph-deploy osd activate CVM-0-11:/dev/hioa1 Can anyone help me to create a kvstore backend OSD?
Attached script should work (configured to use rocksdb, but just change to leveldb in the obvious place. It does the whole job assuming you want a MON and an OSD on the same host, so you may needed to customize it - or only use the osd part after editing your existing ceph.conf.
It expects that the OSD_DATAPATH points to a mounted filesystem (i.e does not make use of ceph-disk).
Also some assumption of Ubuntu (i.e upstart) is made when it tries to start the daemons.
