member specific storage and an optional quorum disk. Member specific files paths were enhanced symbolic links incorporating the member id of the owning member. Each member had one or zero votes, which, combined with a possible quorum disk, implemented a cluster formation algorithm similar to that found in OpenVMS. End of Life With their purchase of Compaq in 2002, HP announced their intention to migrate many of Tru64 UNIX's more innovative features (including its AdvFS, TruCluster, and LSM) to HP-UX. In December 2004, HP announced a change of plan: they would instead use the Veritas File System and abandon the Tru64 advanced features. In the process, many of the remaining Tru64 developers were laid off. The last maintenance release, 5.1B-6 was released in October 2010. In October 2010, HP stated that they would continue to support Tru64 UNIX until 31 December 2012. In 2008, HP contributed the AdvFS filesystem to the open-source community. Versions These versions were released for Alpha AXP platforms.
