Comment 3 Preethi 2020-11-20 13:02:47 UTC

@Juan, Issue is not seen with the latest pacific image. Below are the steps followed

Step 1) ceph osd rm ID#6 -> follow OSD removal process to remove the OSD 6 (except auth del step)
now issue only Ceph orch OSD rm 7--replace (i.e /dev/sdc)

Now try adding the removed OSD#6 from magna073 i/e /dev/sdb disk

(Perform Zap to wipe the data before adding)

/bin/podman:stderr --> Zapping successful for: <Raw Device: /dev/sdb>

[ceph: root@magna094 /]# ceph orch daemon add osd magna073:/dev/sdb
