Lustre 2.0 Release Milestone Status

Lustre 2.0 Alpha April 16, 2009
Summary

The goal of the first Alpha release of Lustre 2.0 is to demonstrate basic stability of Lustre on a single platform/distro. For this release, RHEL5/x86_64 was selected because it is the most often downloaded distribution from lustre.org. To achieve our goal, daily acc-sm runs will be executed on small test clusters and bug fixing priority will focus on fixing bugs which prevent clean acc-sm runs. Additionally, IOR and simul runs will be executed on a modest cluster (approx 75 clients) to verify basic stability. During this Alpha phase, only bug fixes advancing stability will be landed, all other HEAD landing requests will be held and deferred to a later landing date post Alpha.
