Description
This presentation introduces Apollon and Hermes, two complementary tools that automate the complete disk lifecycle. Apollon is a centralized gRPC service that manages automated draining, intelligent repair of failed drains through dynamically-loaded plugin strategies, and systematic leftover file handling. Hermes runs on each storage node, interfacing with repair catalogue systems to detect disk failures, coordinate draining with Apollon, and automatically register replacement disks.
Together, these tools transform disk operations from a multi-step manual process into an automated workflow requiring intervention only for physical disk replacement, significantly reducing operational fragmentation while enhancing reliability.
