You have 23 pgs that are "backfill_toofull". You need to identify these pgs.
You could try increasing the backfill full ratio for those pgs.
ceph health detail
ceph tell osd.<id> injectargs '--osd-backfill-full-ratio=0.90'
Keep in mind new storage needs to be added to the cluster as soon as possible
but I guess that's what you are trying to do.
You could also look at reweighting the full OSDs if you have other OSDs with
considerable space available.
