most probably you're suffering from a per-pool omap statistics update. Which is performed during the first start of an upgraded OSD. One can disable this behavior via 'bluestore_fsck_quick_fix_on_mount' flag. But please expect incomplete OMAP usage report if stats are not updated.

Thanks! If there is no technical issue with it, I think I could just configure bluestore_fsck_quick_fix_on_mount in ceph.conf, do the upgrade 'quick' and afterwards remove the configline and restart the osd's again at a more convenient time? -- Mark Schouten | Tuxis B.V.
