Hi Tobi, Thanks for your response. While I hadn’t tried restarting the active mgr, I did effectively accomplish the same result by failing it out with `ceph mgr fail`, thereby starting a new mgr process in another container. I’ve since tried restarting the active mgr, but it didn’t make any difference.
Eventually `ceph orch device ls` stops producing any output. After restarting or failing over the mgr it will report stale results from a few weeks ago until it attempts to refresh the device list. At that point it stops producing output again. I think this is the root cause of our problem. I followed your suggestions of checking the ceph-volume.log and the cephadm debug output. I didn’t see any obvious problems, but I didn’t have a lot of time to work on this yesterday. I hope to spend more time looking at these logs today.

Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> EXTERNAL EMAIL | USE CAUTION Hi Bob, have you tried to restart the active mgr? ( sometimes mgr gets stuck and prevents the orchestrator from working correctly ). Regarding the orchestrator device scan: have a look into the ceph-volume.log on the corresponding host. you will find it under /var/log/ceph/CLUSTER-ID/ceph-volume.log this log is generated by the device scan from the orchestrator. It may also help to have a look at cephadm debug logs - see https://docs.ceph.com/en/latest/cephadm/operations/#watching-cephadm-log-messages Cheers, tobi Am Mi., 23.

The orchestrator is generally working, but It appears to be unable to scan devices. Immediately after failing out the mgr `ceph orch device ls` will display device status from >4 weeks ago, which was when we converted the cluster to be managed by cephadm. Eventually the orchestrator will attempt to refresh its device status. At this point `ceph orch device ls` stops displaying any output at all. I can reproduce this state almost immediately if I run `ceph orch device ls —refresh` to force an immediate refresh. The mgr log shows events like the following just before `ceph orch device ls` stops reporting output (one event for every osd node in the cluster): "Detected new or changed devices on ceph-osd31” Here are the osd services in play: # ceph orch ls osd NAME PORTS RUNNING REFRESHED AGE PLACEMENT osd 95 8m ago - <unmanaged> osd.ceph-osd31 4 8m ago 6d ceph-osd31 # ceph orch ls osd --export service_type: osd service_name: osd unmanaged: true spec: filter_logic: AND objectstore: bluestore --- service_type: osd service_id: ceph-osd31 service_name: osd.ceph-osd31 placement: hosts: - ceph-osd31 spec: data_devices: rotational: 0 size: '3TB:' encrypted: true filter_logic: AND objectstore: bluestore I tried deleting the default “osd” service in case it was somehow conflicting with my per-node spec, but it looks like that’s not allowed, so I assume any custom osd service specs override the unmanaged default. # ceph orch rm osd Invalid service 'osd'. Use 'ceph orch ls' to list available services. My hunch is that some persistent state is corrupted, or there’s something else preventing the orchestrator from successfully refreshing its device status, but I don’t know how to troubleshoot this. Any ideas? Cheers, /rjg P.S. @Eugen: When I first started this thread you said it was unnecessary to destroy an osd to convert it from unmanaged to managed. Can you explain how this is done? Although we want to recreate the osds to enable encryption, it would save time, and unnecessary wear on the SSDs, while troubleshooting.

Zitat von Bob Gibson <r...@oicr.on.ca<mailto:r...@oicr.on.ca>>: I’ve been away on vacation and just got back to this. I’m happy to report that manually recreating the OSD with ceph-volume and then adopting it with cephadm fixed the problem. Thanks again for your help Eugen!

I see two other options right now. The first would be to purge osd.88 from the crush tree entirely. The second approach would be to create an osd manually with ceph-volume, not cephadm ceph-volume, to create a legacy osd (you'd get warnings about a stray daemon). If that works, adopt the osd with cephadm. I don't have a better idea right now. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io<mailto:ceph-users@ceph.io> To unsubscribe send an email to ceph-users-le...@ceph.io<mailto:ceph-users-le...@ceph.io> -- Best Regards, Tobias Fischer Head of Ceph Clyso GmbH p: +49 89 2152527 41 a: Hohenzollernstraße 27 | 80801 München | Germany w: https://clyso.com<https://clyso.com/> | e: tobias.fisc...@clyso.com<mailto:tobias.fisc...@clyso.com> We are hiring: https://www.clyso.com/jobs/ --- Geschäftsführer: Dipl.
