What if I stored data in my mouse

The author experimented with storing data in a Logitech mouse's flash memory. Logitech mice communicate through HID++, a protocol that maps device features using stable IDs. Despite efforts to write data to certain registers, only the DPI register could retain data across power cycles... read more ย

Pelagia is a Kubernetes controller that provides all-in-one management for Ceph clusters installed byย Rook. It delivers two main features:

Aggregates all Rook Custom Resourcesย (CRs) into a singleย CephDeploymentย resource, simplifying the management of Ceph clusters.
Provides automated lifecycle managementย (LCM) of Rook Ceph OSD nodes for bare-metal clusters. Automated LCM is managed by the specialย CephOsdRemoveTaskย resource.

It is designed to simplify the management of Ceph clusters in Kubernetes installed byย Rook.

Being solid Rook users, we had dozens of Rook CRs to manage. Thus, one day we decided to create a single resource that would aggregate all Rook CRs and deliver a smoother LCM experience. This is how Pelagia was born.

It supports almost all Rook CRs API, includingย CephCluster,ย CephBlockPool,ย CephFilesystem,ย CephObjectStore, and others, aggregating them into a single specification. We continuously work on improving Pelagia's API, adding new features, and enhancing existing ones.

Pelagia collects Ceph cluster state and all Rook CRs statuses into singleย CephDeploymentHealthย CR. This resource highlights of Ceph cluster and Rook APIs issues, if any.

Another important thing we implemented in Pelagia is the automated lifecycle management of Rook Ceph OSD nodes for bare-metal clusters. This feature is delivered by theย CephOsdRemoveTaskย resource, which automates the process of removing OSD disks and nodes from the cluster. We are using this feature in our everyday day-2 operations routine.
