Are you on 12.1.0 or 12.1.1? I noticed that in 12.1.0 the ceph command was missing options that were supposed to be there, but 12.1.1 had them. Maybe you're seeing a similar issue? -----Original Message----- From: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx] On Behalf Of Kenneth Waegeman Sent: Tuesday, July 25, 2017 7:15 AM To: ceph-users@xxxxxxxxxxxxxx Subject: ceph-disk --osd-id param Hi all, From the release notes of the Luminous RC, I read: 'There is a simplified OSD replacement process that is more robust.' , linked to http://docs.ceph.com/docs/master/rados/operations/add-or-rm-osds/#replacing-an-osd If I try running 'ceph-disk prepare --bluestore /dev/sdX --osd-id {id} --osd-uuid `uuidgen`' I get 'ceph-disk: error: unrecognized arguments: --osd-id 6' I checked the source code and indeed, the param is in master, but not in the rc release tag. Will this option still be added for Luminous? Thanks!!
