The ccm fs_check command is responsible for checking that the metadata, cache, and archive portions of a database are consistent.

The ccm fs_check command has a new -c|-cutoff_time time option. Any object versions checked in before the cutoff time but not yet archived produce a warning. The default cutoff is -2:0:0:0. You receive a warning for any files that were checked in earlier than the day before yesterday but have not yet been archived.
