Okay, it's accessible now. From a first glance (I won't have much time over the next days) the numbers seem to match: One PG has a size of around 22 GB, having 2048 PGs results in roughly 42 TB, which matches your 'ceph df' output. I don't exactly recall if Ceph Octopus displayed usage information differently than newer releases, but I think it should match in general, especially with rbd. But there might be tombstones in the rocksDB of the OSDs, have you tried compaction? Offline compaction is usually better than online compaction, so you might want to stop one OSD by one and use the ceph-kvstore-tool for that. But I don't expect it to free up that much space. You could also try to 'rbd sparsify' a couple of images and see if you get some space back. Zitat von lfsilva@binario.cloud:
