Hi, I have recently been scanning the files in a PG with "cephfs-data-scan pg_files ...".
Although, after a long time the scan was still running and the list of files consumed 44 GB, I stopped it, as something obviously was very wrong. It turns out some users had symlinks that looped and even a user had a symlink to "/". It does not make sense that cephfs-data-scan follows symlinks, as this will give a wrong picture of what files are in the target PG. I have looked though CEPHs bug reports, but I do not see anyone mentioning this. Although I am still on the recently deprecated Octopus, I suspect that this bug is also present in Pacific and Quincy? It might be related to this bug? https://tracker.ceph.com/issues/46166 But symptoms are different. Or, maybe there is a way to disable the following of symlinks in "cephfs-data-scan pg_files ..."?
