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.

This first alpha release of Lustre 2.0 can be downloaded from http://downloads.lustre.org/public/lustre/v2.0/alpha/Lustre_2.0_Alpha/

The following documentation related to this alpha is available:

Lustre 2.0 Alpha-2 May 12, 2009

The focus of the second Alpha release (Alpha-2) of 2.0 was to continue improve stability of Lustre while landing queued fixes to HEAD and completing additional bug fixes. 85 total fixes were landed during this cycle.

This release was tested on RHEL5/x86_64 and SLES 10/x86_64 with both IB and TCP connectivity. Known failures are documented in the HEAD Daily Testing Document available from lustre.org. Additionally, IOR and simul runs were executed iteratively on a modest cluster (approx 75 clients) and run for 18 hours successfully with iSCSI attached HW in file per process mode. IOR and Simul were tested on a larger direct attach cluster and IOR has run successfully for 4 hours.
