Submitted by gpmidi on Wed, 06/03/2020 - 13:36

Ceph has two forms of scrubbing that it runs periodically: Scrub and Deep Scrub

A Scrub is basically as fsck for replicated objects. It ensures that each object's replicas are all the latest version and exist. 

A Deep Scrub is a full checksum validation of all data.
