Re: cephadm found duplicate OSD, how to resolve?

Hi,

there was a similar thread recently (https://lists.ceph.io/hyperkitty/list/ceph-users@xxxxxxx/message/WSVIAZBFJQKBXA47RKISA5U4J7BHX6DK/). Check the output of 'cepham ls' on the node where the OSD is not running and remove it with 'cephadm rm-daemon --name osd.3'. If there's an empty directory for that OSD (/var/lib/ceph/osd/ceph-3) remove it as well.

Zitat von Stefan Kooman <stefan@xxxxxx>:

Hi,

I'm in the process of re-provisioning OSDs on a test cluster with cephadm. One of the OSD id's that was supposedly previously living on host3 is now alive on host2. And cephadm is not happy about that:

"Found duplicate OSDs: osd.3 in status running on host2, osd.3 in status stopped on host3."

As far as I can see there has never been an osd 3 on host3 managed by cephadm (there used to be an osd.3 when this cluster was ceph-ansible managed).

How can I find what cephadm's view of the world is? And tell cephadm it should forget about osd.3 on host3, without destroying osd.3 on host2?

Thanks,

Gr. Stefan
