Hello,
here goes multipath-tools-0.4.5
This release was long due.
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
