Ceph is OUT! MinIO & Longhorn – The Future?
Key points from the YouTube video transcript:
-
Lab Update & Storage Alternatives: The video focuses on an update to the presenter’s lab, specifically replacing Gluster storage (version 11, four years old). Two alternatives are explored: Minio and Longhorn.
-
Minio: A lightweight, high-performance object store that primarily works with the XFS file system (though it can theoretically work with others, it’s not officially supported). It’s essentially a locally-run S3 bucket, compatible with Amazon S3. The presenter demonstrates basic Minio functionality, including bucket creation and file upload/download. It’s open-source (GNU AGPLv3).
-
Longhorn: Designed for Kubernetes clusters. The presenter mentions it but doesn’t demonstrate it in this video.
-
Installation Challenges: The presenter details challenges encountered installing Minio, specifically mentioning the need for manual systemD configuration when installing from binaries (as opposed to using pre-built packages for Red Hat or Debian). Securing the server for Let’s Encrypt certificate verification also presented difficulties.
-
Future Plans: The presenter intends to further investigate and test both Minio and Longhorn, including multi-node cluster testing to assess performance across multiple machines. They will likely use different hardware configurations for these tests.
In short, the video is a progress report on a lab upgrade, focusing on the initial setup and challenges encountered with the Minio object storage solution. Longhorn is mentioned as a future focus.
