Lustre 2.0 Alpha April 16, 2009
The goal of the first Alpha release of Lustre 2.0 was 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 were executed on small test clusters and bug fixing priority focused on fixing bugs that prevented clean acc-sm runs. Additionally, IOR and simul runs were executed on a modest cluster (approx 75 clients) to verify basic stability. During this Alpha phase, only bug fixes advancing stability were landed. All other HEAD landing requests were held and deferred to a later landing date post Alpha.
