2003-12-29 multipath-012 * refresh doc * add the uninstall target in Makefile 2003-12-22 multipath-010 * tweak the install target in Makefile * stop passing fds as argument : this change enable a strict segregation of ugly 2.4 code * sysfs version of get_lun_strings() * be careful about the return of get_unique_id() since errors formerly caught up by if(open()) in the caller fn are now returned by get_unique_id() * send get_serial() in unused.c * introduce dm-simplecmd for RESUME & SUSPEND requests * split add_map() in setup_map() & dm-addmap() * setup_map() correctly submits "SUSPEND-RELOAD-RESUME or CREATE" sequences instead of the bogus "RELOAD or CREATE" * 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 * multipath 0.0.1 released. * Initial release.
