Hi Dan, just restarted all MONs, no change though :( Thanks for looking at this. I will wait until tomorrow. My plan is to get the disk up again with the same OSD ID and would expect that this will eventually allow the message to be cleared.

The cluster looks absolutely healthy except of this osd.584 Probably, the purge will help the cluster to forget this faulty one.

Its probably stuck in some part of the health checking that tries to query 580 and doesn't understand that the OSD being down means there are no ops. > > I tried to restart the OSD on this disk, but it seems completely rigged. The iDRAC log on the server says that the disk was removed during operation possibly due to a physical connection fail on the SAS lanes. I somehow need to get rid of this message and am wondering of purging the OSD would help. > > Best regards, > ================= > Frank Schilder > AIT Risø Campus > Bygning 109, rum S14 > > ________________________________________ > From: Vladimir Sigunov <vladimir.sigunov@xxxxxxxxx> > Sent: 03 May 2021 13:45:19 > To: ceph-users@xxxxxxx; Frank Schilder > Subject: Re: OSD slow ops warning not clearing after OSD down > > Hi Frank. > Check your cluster for inactive/incomplete placement groups.

An OSD went down and recovery finished.
