Description of problem: Creating OSD with "ceph-volume lvm batch" show "% of device" as 0% for DB device if that device is already serving as DB for other OSD's. Version-Release number of selected component (if applicable): RHCS 4.2 How reproducible: 1: Create an non-collocated OSD. #ceph-volume lvm batch --bluestore /dev/sda /dev/nvme0n1 2: Now create another OSD using same DB device to utilize remaining space on DB device. #ceph-volume lvm batch --bluestore /dev/vdc /dev/nvme0n1 3: If we use DB '--deb-devices' flag at this point, it ignores the DB device completely and create a collocated OSD. #ceph-volume lvm batch --bluestore /dev/vdc --db-devices /dev/nvme0n1 --report
https://tracker.ceph.com/issues/51107 is resolved in v14.2.22 upstream, and we've rebased to that version, so I'm moving this to ON_QA.
(Er, that previous comment was for RHCS 4.3). For RHCS 5.1: https://tracker.ceph.com/issues/51108 is resolved in v16.2.5 upstream, and we've rebased ceph-5.1-rhel-patches to v16.2.6, so I'm moving this to ON_QA.
