Description

Parallel deep-scrubs have the potential to cause client I/O contention. A mechanism to spread out deep-scrubs and make them less clumpy would be desired. Perhaps even scaling osd_deep_scrub_interval to match defined load/IO requirements (to a certain extent), and spreading deep-scrubs amongst that period.
