[ceph-users] Cannot stop OSD

Hello, I am running a Ceph cluster installed with cephadm. Version is 18.2.2 reef (stable). I am moving the DB/WAL from my HDDs to SSD, and have been doing fine on all the OSDs until I got to one in particular (osd.14) From the cephadm shell, when I run 'ceph orch daemon stop osd.14', nothing happens: it does not get marked as Down. If I mark is as Down in the GUI, it does show as Down then a few seconds later it gets marks as Up again. I was running 'journalctl -xf | grep osd.14' to see if any errors came up, but nothing did. Not sure where to check next to try to sort this out?
