Release Testing

Test plans are available for upcoming Lustre releases.

Lustre 1.8 Test Plan (coming soon)

Lustre 2.0 Test Plan (coming soon)

Feature Testing

This section lists the feature test plans used by the Lustre QE team.

OST Pools

This is the Test Plan for OST Pools. The objective is to test OST Pools on a large-scale cluster to make sure the feature is scalable, and verify that file creation performance is the same (with or without OST Pools).

Quotas

This is the Test Plan for Lustre Quotas. The test plan's objective is to:

  • Thoroughly test the quotas feature (block and inode quotas for users and groups) for each new Lustre release (during pre-release testing)
  • Focus on quotas hard limits
  • Find and document problems with quotas (and add them as release blockers).
  • Deliver working quotas feature code to Cray, Inc. with each new Lustre release and avoid bugs (especially regressions)

The components to be tested are:

  • ldiskfs
  • Lustre
  • lustre quotas feature code

Lustre Security

This is the Test Plan for Security Features. The test plan's objective is to find defects in the Lustre 2.0 security features and drive the security source code to a stable, production-ready state. The test plan contains:

  • Complete acceptance-small (acc-sm) run that shifts among different security flavors (null, krb5i and krb5p) between tests.
  • Complete I/O benchmark (IOR and mdsrate), to run against all Lustre-supported security flavors (null, plain, krb5n, krb5a, krb5i and krb5p), gather and analyze performance data.

Version-Based Recovery

This is the Test Plan for Version-Based Recovery. The test plan's objective is to verify that the VBR feature works with a large system.
