I just move one PG away from the OSD, but the diskspace will not get freed.
How did you move? I would suggest you use upmap:
ceph osd pg-upmap-items
Invalid command: missing required parameter pgid(<pgid>)
osd pg-upmap-items <pgid> <osdname (id|osd.id)> [<osdname
(id|osd.id)>...] : set pg_upmap_items mapping <pgid>:{<id> to <id>,
[...]} (developers only)
So you specify which PG has to move to which OSD.
Do I need to do something to clean obsolete objects from the osd?
No. The OSD will trim PG data that is not needed anymore.
