I am using Ceph, uploading many files through radosgw. After, I want to delete the files. I am trying to do that in Python, like this:
bucket = conn.get_bucket(BUCKET)
for key in bucket.list():
bucket.delete_key(key)
Afterwards, I use bucket.list()
to list files in the bucket, and this says that the bucket is now empty, as I intended.
However, when I run ceph df
on the mon, it shows that the OSDs still have high utilization (e.g. %RAW USED 90.91
). If I continue writing (thinking that the status data just hasn't caught up with the state yet), Ceph essentially locks up (100% utilization).
What's going on?
Note: I do have these standing out in ceph status
:
health HEALTH_WARN
3 near full osd(s)
too many PGs per OSD (2168 > max 300)
pool default.rgw.buckets.data has many more objects per pg than average (too few pgs?)
From what I gather online, this wouldn't cause my particular issue. But I'm new to Ceph and could be wrong.
I have one mon and 3 OSDs. This is just for testing.
UPDATE: The space does seem to be reclaimed, very slowly. It went down to 63% utilization after an hour or so.
