I have 1 CIF that will not start Deduplication. All others have completed. There are currently no deduplication going on. Deduplication is turned on.
Look at the logs via server_log
turn deduplication for this FS on, even if it is already turned on. This will reschedule an dedup scan. The dedup scan will start, when no other dedup scan is running.
Monitor the server_log for dedupe messages, f. e. NoSpace.
