DRBD - 8.0.0 ============ This is the official entry to the changelog: 8.0.0 (api:86/proto:86) -------- * No effecitve changes to rc2. But I want to remind you about the changes relative to the 0.7 release of DRBD: ---------------- * Removed support for Linux-2.4.x * Cleanup of the wire protocol. * Added optional peer authentication with a shared secret. * Consolidated state changes into a central function. * Improved, tunable after-split-brain recovery strategies. * Always verify all IDs used in the protocol that are used as pointers. * Introduced the "outdate" disk state, and commands for managing it. * Introduced the "drbdmeta" command, and require the user to create meta-data explicitly. * Support for primary/primary (for OCFS2, GFS...) * Replaced the sync-groups with the sync-after mechanism. * The "common" section in the configuration file. * Replaced the generation counters (GCs) with data-generation-UUIDs * Improved performance by using Linux-2.6's BIOs with up to 32k per IO request. Before we transferred only up to 4k per IO request. * A Warning if the disk sizes are more than 10% different. * A connection teardown packet to differentiate between a crash of the peer and a peer that is shut down gracefully. * External imposable SyncPause states, to serialize DRBD's resynchronisation with the resynchronisation of backing storage's RAID configurations. * Backing storage can be hot added to disk less nodes. * Prepared for advanced integration to Heartbeat-2.0 * Changed internal APIs so that missed writes of the meta-data super block are reported as they happen. * The http://usage.drbd.org sub project. * Rewrote the scanner/parser of drbd.conf. 10 times smaller/faster and easier to maintain. * Asynchronous meta-data IO [ Code drop from the DRBD+ branch ] http://oss.linbit.com/drbd/8.0/drbd-8.0.0.tar.gz http://svn.drbd.org/drbd/tags/drbd-8.0.0/ http://www.linbit.com/support/drbd-8.0.0/ To have our release policy more transparent in the future: Bugfix releases will increase the 3rd number, e.g. 8.0.1, 8.0.2 etc... Releases that introduce small new features will increase the second number, resetting the third number: 8.1.0 etc... In the next weeks we will try to update the http://www.drbd.org with a bit of new content. Oh, yes, and then we will prepare it for inclusion into Linus' mainline Linux. -Phil -- : Dipl-Ing Philipp Reisner Tel +43-1-8178292-50 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Vivenotgasse 48, 1120 Vienna, Austria http://www.linbit.com :
