A must have tools collection for Gluster Geo-replication users!

Currently this repository contains gluster-georep-setup and gluster-georep-status tools. More tools will be added in future. Let me know if you need any specific tool to manage Gluster Geo-replication.

gluster-georep-setup was previously called as georepsetup (Blog about georepsetup is here).

Installation

Install the tools collection using, pip install gluster-georep-tools. Binary packages are not yet available, hopefully I will work on the packaging in near future.

gluster-georep-status

Wrapper around Geo-rep status command and Volume info command to provide more features compared to Gluster CLI. This tool combines Geo-rep status and Volume info to get following advantageous.

  • Nodes will be displayed in the same order as in Volume info

  • Offline nodes are shown with "Offline" as status

  • Status output from different sessions are not mixed.

  • Filters are available(Ex: --with-status=active, --with-crawl-status=changelog, --with-status=faulty etc)

  • Shows summary of number of workers per status

Example output(Listing all the sessions, gluster-georep-status:
