Summary
Ubuntu supports a variety of HA solutions in main. These tools and solutions need to be constantly updated and maintained.
Rationale
A lot of improvements have been done on these tools since edgy release. These improvements need to be incorporated into feisty.
Use cases
- Company foo wants to run the latest version of Ubuntu on their redhat cluster and oracle cluster. They expect Ubuntu to keep up with the development done from upstream.
- Company bar wants to deploy a new redhat cluster suite and it expects Ubuntu to provide the very latest conga suite for cluster deployment and use GFS2 due to its performance improvements.
Implementation
- Update GFS/GFS2/OCFS2 kernel support and userland.
- Package conga from redhat cluster suite to replace system-config-cluster.
Data preservation and migration
Our kernel supports all the 3 major clustered FS. The migration path is therefor very smooth. RedHat upstream agreed with us to support GFS for a much longer term in order to make gfs -> gfs2 migration smoother.
Unresolved issues
- conga packaging complexity.
