Is this documented somewhere? Because I would like to try this disk encryption without lvm. I thought about just creating a regular bluestore disk, and then use dmcrypt on the 'ceph block' partition and use crypttab to automatically mount it. And then have ceph use this device dmcrypt device by changing /var/lib/ceph/osd/ceph-xx/block and /var/lib/ceph/osd/ceph-xx/block_uuid, but that does not seem to work. -----Original Message----- From: Marc Roos Sent: donderdag 31 mei 2018 17:11 To: ceph-users Subject: What is osd-lockbox?
