I hope those aren't SMR disks... make sure they're not or it will be
very slow, to the point where *osds will time out and die*.

This is not for performance, just for cold data.
ceph osd crush move osd.X host=nodeY
If your journals aren't being moved too, then flush the journals after
the osds are stopped:
sync
ceph-osd --id $n --setuser ceph --setgroup ceph --flush-journal
(if that crashes, start the osd, then stop again, and retry)
and before starting them, make new journals.
ceph-osd --id $n --setuser ceph --setgroup ceph --mkjournal
Perfect ! There was a way. thanks
