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? R
