[ceph-users] fsck error: found stray omap data on omap_head

We just upgraded to pacific, and I'm trying to clear warnings about legacy bluestore omap usage stats by running 'ceph-bluestore-tool repair`, as instructed by the warning message. It's been going fine, but we are now getting this error: [root@vanilla bin]# ceph-bluestore-tool repair --path $osd_path 2021-05-19T19:25:26.485+0000 7f67ca3593c0 -1 bluestore(/var/lib/ceph/osd/ceph-9) fsck error: found stray omap data on omap_head 12256434 0 0 repair status: remaining 1 error(s) and warning(s) [root@vanilla bin]# ceph-bluestore-tool fsck --path $osd_path -deep 2021-05-19T20:03:17.002+0000 7f4d1d6603c0 -1 bluestore(/var/lib/ceph/osd/ceph-9) fsck error: found stray omap data on omap_head 12256434 0 0 fsck status: remaining 1 error(s) and warning(s) We're only 10% of the way through our OSDs, so I'd like to find some way to fix this other than destroying and rebuilding the OSD, in case it happens again. Fixing this error is especially attractive since we can't get out of HEALTH_WARN until we've run recover on all OSDs. Any suggestions?
