Running DeepSea stage 3 again results in additional OSD's (Object Storage Daemons) on existing OSD devices

SUSE Enterprise Storage 6
OSD Encryption


Re-running DeepSea stage 3 or running the disks deployment runner again results in additional OSDs being created on any already existing OSD devices.


NOTE: The issue described here is resolved with deepsea-0.9.33 and ceph- or later.

If the cluster is not running at least the above versions then refrain from running DeepSea stage 3 multiple times or manually running the disk deployment runner.
A possible workaround can be to adjust the "/srv/salt/ceph/configuration/files/drive_groups.yml" file in such a way that no devices would match, or that only specific new devices will be matched. It can then be verified by looking at the output of "salt-run disks.list" on the master node that no devices are being matched e.g. for each node the return should show no device information or only specific new device information:
Also see the "Additional Information" section below.


Due to a bug in ceph-volume, device mapper devices created when encryption is used are always marked as available for OSD deployment.

Additional Information

Looking at the output of "ceph-volume inventory" or "ceph-volume inventory --format jason-pretty" shows the device mapper devices and their availability as True, for example:
 /dev/mapper/gARFUj-qlA9-PQHB-qqps-HkBG-l11C-q19Ezo 1.07 TB      True    True
In addition to the above mentioned workaround, it should also be possible to run certain components of stage 3 "standalone" or to create a custom stage 3 that excludes disk deployment.
