* 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.
