How are you uploading a file? RGW, librados, CephFS, or RBD? There are multiple reasons that the space might not be updating or cleaning itself up. The more information you can give us about how you're testing, the more we can help you.

How did you check the space utilization? I believe the reason that you are still seeing the space being utilized when you issue your ceph -df is because even after the file is deleted, the file system doesn't actually delete the file, it just removes the file inode entry pointing to the file. The file will still be on the disk until the blocks are re-allocated to another file.-JamieOn Thu, Oct 19, 2017 at 11:54 AM, nigel davies <nigdav007@xxxxxxxxx> wrote:Hay allI am looking at my small test Ceph cluster, i have uploaded a 200MB iso and checked the space on "ceph status" and see it incress.But when i delete the file the space used does not go down.Have i missed a configuration somewhere or something?
