Hi,
There is no need to rebuild all ODS. You can follow the procedure
described by RedHat[0] to convert the DB and tell the OSD to use
rocksdb.
Couldn't find this documented elsewhere. You may need a RedHat account
to access the content, but you could create a developer one for free
IIRC.

Thanks guys,
I was able to convert some OSDs to rocksdb just fine (the ceph-kvstore-tool was in the ceph-test debian package). I'm going to let that run for a few days on one host before converting the others.
I really hope this helps with the heavy write/delete load kicking out OSDs.
