The normal filewalker always was that way. We didn’t made it silent. We later added more logging for the lazy filewalker but it is a different code path so these additional log lines don’t show up when running the normal filewalker.
There is an easy trick to find out if the filewalker (both normal and lazy) is still running. You can also check if garbage collection is currently running. Guide to debug my storage node, uplink, s3 gateway, satellite and there go for /mon/ps and also useful is /mon/funcs
