Full of new shiny features. Worth noting : * multipathd keeps Device Mapper path status in sync with path checker status : proactive fail_path and reinstate_path * proactive path group re-enable, as soon as one path goes up * multipathd is now fully event driven : o NetLink? uevents for kernels/distro that enables the feature o Hotplug o Unix socket messages * a Command Line Interface to drive and inspect the daemon * remove the multipath(8) cache file logic in favour of a multipathd<->multipath unix socket request/reply design * split multipath(8) listing option into o short-list (-l) : don't fetch wwid, path checker status, priorities ... fast o detailed-list (-ll) : refetch all info * the daemon asynchronous logger is now solid and avoid sending critical messages * daemon CLI command to reload the config file * path checking interval gets longer when the path is reliably up, resets to short as soon as a problem occur * daemon implements 3 path group failback methods : o manual o immediate : failback as soon as an (enabled && !active) PG gets the highest priority o defered : failback to the highest priority (enabled && !active) PG n seconds after the last PG priority order change * remove over-complicated and thread-confusing daemon initial clone() w/ private namespace * prioritizers official prefix is now mpath_prio_ * multipath(8) displays PG priorities when available * new hp_sw checker. It's a tri-state UP/DOWN/GHOST * new directio checker. Useful with DASD devices. May suplant readsector0 in the long run ? * stricter default blacklist regexps * new '-f' multipath(8) flag to selectively suppress a multipath map, and its device-mapped partitions * alua prioritizer update, should work on x86 * support for >2TB multipaths * claimed device detection : no more warning/error messages with paths pinned by mounted FS * option to use priorities as weights in the round-robin scheduler : for people who can't wait for a qlen-based scheduler As usual, doc and download at : http://christophe.varoqui.free.fr/ Archive mirror at ftp://sources.redhat.com/pub/dm/multipath-tools/ Regards, -- christophe varoqui ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ Linux-hotplug-devel mailing list http://linux-hotplug.sourceforge.net Linux-hotplug-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-hotplug-devel
