Sébastien Han 7d657ac643 osd: ability to set db and wal to bluestore ... This commits refactors how we deploy bluestore. We have existing scenarios that we don't want to change too much. This commits eases the user experience by now changing the way you use scenarios. Bluestore is just a different interface to store objects but the scenarios more or less remain the same. If you set osd_objectstore == 'bluestore' along with journal_collocation: true, you will get an OSD running bluestore with DB and WAL partitions on the same device. If you set osd_objectstore == 'bluestore' along with raw_multi_journal: true, you will get an OSD running bluestore with a dedicated drive for the rocksdb DB, then the remaining drives (used with 'devices') will have WAL and DATA collocated. If you set osd_objectstore == 'bluestore' along with raw_multi_journal: true and declare bluestore_wal_devices you will get an OSD running bluestore with a dedicated drive for rocksdb db, a dedicated drive partition for rocksdb WAL and a dedicated drive for DATA.
