2003-12-22 multipath-010
* don't print .sg_dev if equal to .dev (2.6) in print_path()
* since the kernel code handles defective paths, remove all
code to cope with them :
* move do_tur() to unused.c
* remove .state from path struct
* remove .state settings & conditionals
* add a cmdline switch to force maps to failover mode,
ie 1 path per priority group
* add default policies to the whitelist array (spread io ==
MULTIBUS / io forced to 1 path == FAILOVER)
* move get_disk_size() call out of add_map() to coalesce()
* comment tricky coalesce() fn
* bogus unsused.c file renamed to unused.c
2003-12-20 multipath-010
* big ChangeLog update
* start to give a little control over target params :
introduce cmdline arg -i to control polling interval
* cope with hotplug-style calling convention :
ie "multipath scsi $DEVPATH" ... to avoid messing with
online maps not concerned by an event
* example hotplug agent to drop in /etc/hotplug.d/scsi
* revert the run & resched patch : unless someone proves me
wrong, this was overdesigned
* move commented out functions in unused.c
* update multipath target params to "udm[23] style"
* mp target now supports nr_path == 1, so do we
* add gratuitous free()
* push version forward
2003-12-15 multipath-009
* Make the HW-specific get_unique_id switch pretty
* Prepare to field-test by whitelisting all known fibre array,
try to fetch WWID from the standard EVPD 0x83 off 8 for everyone
* configure the multipath target with round-robin path selector and
conservative default for a start (udm1 style) :
yes it makes this release the firstreally useful one.
* temporarily disable map creation for single path device
due to current restrictive defaults in the kernel target.
Sistina should work it out.
* correct the strncmp logic in blacklist function.
* update the Makefiles to autodetect libgcc.a & gcc includes
"ulibc-style". Factorisation of udevdirs & others niceties
* drop a hint about absent /dev/sd? on failed open()
* implement a reschedule flag in /var/run.
Last thing the prog do before exit is check if a call to multipath
was done (but canceled by /var/run/multipath.run check) during its
execution. If so restart themain loop.
* implement a blacklist of sysfs bdev to not bother with for now
(hd,md, dm, sr, scd, ram, raw).
This avoid sending SG_IO to unappropiate devices.
* Adds a /var/run/multipath.run handling to avoid simultaneous runs.
* Remove a commented-out "printf"
* drop a libdevmapper copy in extras/multipath;
maybe discussions w/Sistina folks will bring a better solution in the future.
* drop a putchar usage in libdevmapper to compile cleanly with klibc
* drop another such usage of my own in main.c
* massage the Makefile to compile libdevmapper against klibc
* use "ld" to produce the binary rather than "gcc -static"
* stop being stupid w/ uneeded major, minor & dev in main.c:dm_mk_node()
* reverse to creating striped target for now because the multipath target
is more hairy than expected initialy
* push the version code to 009 to be in synch w/ udev
2003-11-27 multipath-007
* removes sg_err.[ch] deps
* makes sure the core code play nice with klibc
* port the sysfs calls to dlist helpers
* links against udev's sysfs (need libsysfs.a & dlist.a)
* finally define DM_TARGET as "multipath" as Joe posted the code today (not tested yet)
* push version forward (do you want it in sync with udev version?)
2003-11-19
* merged in udev-006 tree
2003-09-18 Christophe Varoqui <christophe.varoqui@free.fr>
* multipath 0.0.1 released.
* Initial release.
