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.
This is the current state
cluster:

resolve itself): 248 pgs backfill_toofull
