Hi, We had to recreate our Ceph cluster and it seems some legacy data was left over. I think this is causing our valid OSD's to hang for 15-20 minutes before starting up on a machine reboot. When checking /var/log/ceph/ceph-volume.log I can see the following - [2022-03-08 09:32:10,581][ceph_volume.process][INFO ] Running command: /usr/sbin/ceph-volume lvm trigger 1-f5f2a63b-540d-4277-ba18-a7db63ce5359 [2022-03-08 09:32:10,592][ceph_volume.process][INFO ] Running command: /usr/sbin/ceph-volume lvm trigger 3-eb671fc9-6db3-444e-b939-ae37ecaa1446 [2022-03-08 09:32:10,825][ceph_volume.process][INFO ] stderr --> RuntimeError: could not find osd.2 with osd_fsid e45faa5d-f0af-45a9-8f6f-dac037d69569 [2022-03-08 09:32:10,837][ceph_volume.process][INFO ] stderr --> RuntimeError: could not find osd.0 with osd_fsid 16d1d2ad-37c1-420a-bc18-ce89ea9654f9 [2022-03-08 09:32:10,844][systemd][WARNING] command returned non-zero exit status: 1 [2022-03-08 09:32:10,844][systemd][WARNING] failed activating OSD, retries left: 25 [2022-03-08 09:32:10,853][ceph_volume.process][INFO ] stderr --> RuntimeError: could not find osd.1 with osd_fsid f5f2a63b-540d-4277-ba18-a7db63ce5359 [2022-03-08 09:32:10,853][ceph_volume.process][INFO ] stderr --> RuntimeError: could not find osd.0 with osd_fsid 59992b5f-806b-4bed-9951-bca0ef4e6f0a [2022-03-08 09:32:10,855][systemd][WARNING] command returned non-zero exit status: 1 [2022-03-08 09:32:10,855][systemd][WARNING] failed activating OSD, retries left: 25 [2022-03-08 09:32:10,865][ceph_volume.process][INFO ] stderr --> RuntimeError: could not find osd.3 with osd_fsid eb671fc9-6db3-444e-b939-ae37ecaa1446 When running ceph-volume lvm list | grep "osd fsid" we only have four OSD's and none match the fsid's mentioned above - osd fsid 3038f5ae-c579-410b-bb6d-b3590c2834ff osd fsid b693f0d5-68de-462e-a1a8-fbdc137f4da4 osd fsid 4639ef09-a958-40f9-86ff-608ac651ca58 osd fsid c4531f50-b192-494d-8e47-533fe780bfa3 How can I tell Ceph to stop looking for these orphaned OSD's / volumes? Thanks, Chris. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
