ZFS focus on Ubuntu 20.04 LTS: ZSys commands for state management

Didier Roche, continuing his series of articles on ZFS in Ubuntu 20.04 LTS, writes this time about managing states within ZSys. Didier provides examples and screenshots that depict zsysctl commands, manual and automatic saves, details on system and user state saves, and manually removing unwanted states in a somewhat tutorial based overview.

ZFS focus on Ubuntu 20.04 LTS: ZSys state collection

In this article in Didier Roche's series on ZFS integration in Ubuntu 20.04 LTS, Didier writes that even though saved states may not use up much disk space over time it still accumulates so we are introduced to the garbage collection strategy. Didier explains with diagrams how it works and gives an overview of the zsys-gc timer and service. As always we are provided a link to join the discussion and provide feedback on the Ubuntu discourse thread.

OpenStack Ussuri for Ubuntu 20.04 and 18.04 LTS
