I am also not an expert, but it looks like you have big data volumes on
few PGs, from what I've seen, the pg data is only deleted from the old
OSD when is completed copied to the new osd.
So, if 1 pg have 100G por example, only when it is fully copied to the
new OSD, the space will be released on the old OSD.
If you have a busy cluster/network, it may take a good while. Maybe just
wait a litle and check from time to time and the space will eventually
be released.

I’m not an expert either so if someone in the list have some ideas on
this problem, don’t be shy, share them with us.
For now, I only have hypothese that the OSD space will be recovered as
soon as the recovery process is complete.
Hope everything will get back in order soon (before reaching 95% or
above).
I saw some messages on the list about the fstrim tool which can help
reclaim unused free space, but i don’t know if it’s apply to your case.

Hi Sebastien,
Below is the query details. I am not that much expert and still
learning . pg's are not stuck stat before adding osd and pg are
slowly clearing stat to active-clean. Today morning there was around
53 active+undersized+degraded+remapped+wait_backfill and now it is 21
only, hope its going on and i am seeing the space keep increasing in
newly added OSD (osd.6)
