The following are known issues in the Lustre 2.9 Release:
- LU-8313 – Deployments using kerberos that have upgraded from an earlier release will need to manually add a–k flag to svcgssd in order to maintain compatibility
- LU-8880 – Kerberos does not behave in a consistent manner when deploying in a DNE configuration
These issues are being actively worked and have proposed fixes under testing and review.
Please log any issues found in the issue tracking system
Thanks to all those who have contributed to the creation of this release.
