-2004-02-21 multipath-018
- * From the Debian SID inclusion review (Philipp Matthias Hahn)
- * use DESTDIR install prefix in the Makefile
- * add man pages for devmap_name & multipath
- * correct libsysfs.h includes
- * fork the hotplug script in its own shell
- * Sync with the kernel device mapper code as of 2.6.3-udm3
- ie. Remove the test interval parameter and its uses
- * Remove superfluous scsi parameter passed from hotplug
- * Add the man pages to the [un]install targets
-2004-02-17 multipath-017
- * remove the restrictive -f flag.
- Introduce a more generic "-m iopolicy" one.
- * remove useless "int with_sysfs" in env struct
-2004-02-04 multipath-016
- * add a GROUP_BY_SERIAL flag. This should be useful for
- controlers that activate they spare paths on simple IO
- submition with a penalty. The StorageWorks HW defaults to
- this mode, even if the MULTIBUS mode is OK.
- * remove unused sg_err.c
- * big restructuring : split devinfo.c from main.c. Export :
- * void basename (char *, char *);
- * int get_serial (int, char *);
- * int get_lun_strings (char *, char *, char *, char *);
- * int get_evpd_wwid(char *, char *);
- * long get_disk_size (char *);
- * stop passing struct env as param
- * add devmap_name proggy for udev to name devmaps as per their
- internal DM name and not only by their sysfs enum name (dm-*)
- The corresponding udev.rules line is :
- KERNEL="dm-[0-9]*", PROGRAM="/sbin/devmap_name %M %m", NAME="%k", SYMLINK="%c"
- * remove make_dm_node fn & call. Rely on udev for this.
- * don't rely on the linux symlink in the udev/klibc dir since
- udev build doesn't use it anymore. This corrects build breakage
-2004-01-19 multipath-013
- * update the DM target synthax to the 2.6.0-udm5 style
-2003-12-29 multipath-012
- * check hotplug event refers to a block device; if not exit early
- * 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 <christophe.varoqui@free.fr>
- * multipath 0.0.1 released.
- * Initial release.
