[ceph-users] Bluestore and number of devices

[Robert Stanford]

 I'm using filestore now, with 4 data devices per journal device.

 I'm confused by this: "BlueStore manages either one, two, or (in certain
cases) three storage devices."
(

)

 When I convert my journals to bluestore, will they still be four data
devices (osds) per journal, or will they each require a dedicated journal
drive now?

You can keep the same layout as before. Most place DB/WAL combined in one
partition (similar to the journal on filestore).
