BeeGFS Upgrade Notes: Version 2015.03 to 6.0 ============================================ This document contains the relevant changes for users who are upgrading from the 2015.03 release series to the v6 release series. * BeeGFS 6.0 changes the versioning scheme from YYYY.MM to MAJOR.MINOR. * New feature - High Availability for Metadata Servers: The most notable new feature in the 6.x release series is support for a new mirroring approach with transparent failover and self-healing on the beegfs-meta servers. See here for more details: http://www.beegfs.com/wiki/AboutMirroring * A complete list of new features, improvements and general changes is available in the changelog here: http://www.beegfs.com/release/beegfs_6/Changelog.txt * For upgrade instructions to preserve existing data and config files, see here: http://www.beegfs.com/wiki/Upgrade2015To6 * On-Disk Format: The BeeGFS 6.x release servers are backwards compatible with the 2015.03 release series storage format, so no data conversion or upgrade tool is required to use existing data with the new release. * Version Interoperability: Clients and servers of 2015.03 and 6.x releases are not interoperable and thus cannot be used together in the same file system instance. However, BeeGFS provides client compatibility packages, which can be installed side-by-side, so it is possible to e.g. install a 2015.03 client and a 6.x client together on the same machine to access different file system instances.
