All; Since I haven't heard otherwise, I have to assume that the only way to get this to go away is to dump the contents of the RGW bucket(s), and recreate it (them)? How did this get past release approval? A change which makes a valid cluster state in-valid, with no mitigation other than downtime, in a minor release. Thank you, Dominic L.

I missed the ID in the ceph df output previously. Next time I'll wait to read replies until I've finished my morning coffee. How would I go about correcting this? The content for this bucket is basically just junk, as we're still doing production qualification, and workflow planning. Moving from Windows file shares to self-hosted cloud storage is a significant undertaking. Thank you, Dominic L. Hilsbos, MBA Director – Information Technology Perform Air International Inc.

To me this seems like a RGW bucket which index grew too big. Use: $ radosgw-admin bucket list $ radosgw-admin metadata get bucket:<BUCKET> And match that UUID back to the bucket.
