Robinhood Policy Engine is a multi-purpose tool for managing the content of large filesystems. It can audit filesystem content, perform accounting, remove old unused files according to admin-defined policies, show customizable alerts based on file properties, backup data to external storage, and more. It has advanced capabilities for Lustre filesystems. It leverages OST usage, and lists or purges files per OST, with policy criteria based on pools and OST index. It can also process MDT changelogs with Lustre v2. Originally developped for HPC, it has been designed to perform all of its tasks in parallel, so it is particularly adapted for running on large filesystems with millions of entries and petabytes of data. But you can nonetheless take advantage of all of its features for managing smaller filesystems.

Its purpose is to provide Microsoft Server-like services on the cloud or on the premises, to run and operate corporate IT environments with Windows- and Linux-based clients, and to extend those environments with proven enterprise software.
digup is a console tool to update md5sum or shasum digest files. It will read existing digest files, check the current directory for new, updated, modified, renamed, or deleted files, and query the user with a summary of changes. After reviewing the updates, they can be written back to the digest file. This makes digup very useful to update and verify incremental archives like chronological data storages, which are commonly stored and backed up on hard disks. Using a full file digest scan, even slowly creeping bad blocks on old hard disks can be detected. By using a crontab entry, this check can be performed unattended and routinely.
