Upgrading journals to BlueStore: a conundrum

[Robert Stanford <rstanford8896@xxxxxxxxx>]

 According to the instructions to upgrade a journal to BlueStore (http://docs.ceph.com/docs/master/rados/operations/bluestore-migration/), the OSD that uses the journal is destroyed and recreated.

 I am using SSD journals, and want to use them with BlueStore.  Reusing the SSD requires zapping the disk (ceph-disk zap).  But this would take down all OSDs that use this journal, not just the one-at-a-time that I destroy and recreate when following the upgrade instructions.

 How then can one upgrade journals to BlueStore when there is more than one journal on the same disk?
