I just move one PG away from the OSD, but the diskspace will not get freed. Do I need to do something to clean obsolete objects from the osd? Am Di., 30. März 2021 um 11:47 Uhr schrieb Boris Behrens <bb@kervyn.de>:

Hi, I have a couple OSDs that currently get a lot of data, and are running towards 95% fillrate.

I would like to forcefully remap some PGs (they are around 100GB) to more empty OSDs and drop them from the full OSDs. I know this would lead to degraded objects, but I am not sure how long the cluster will stay in a state where it can allocate objects.

OSD.105 grew from around 85% to 92% in the last 4 hours.
