3 * start to give a little control over target params :
4 introduce cmdline arg -i to control polling interval
5 * cope with hotplug-style calling convention :
6 ie "multipath scsi $DEVPATH" ... to avoid messing with
7 online maps not concerned by an event
8 * example hotplug agent to drop in /etc/hotplug.d/scsi
9 * revert the run & resched patch : unless someone proves me
10 wrong, this was overdesigned
11 * move commented out functions in unused.c
12 * update multipath target params to "udm[23] style"
13 * mp target now supports nr_path == 1, so do we
14 * add gratuitous free()
15 * push version forward
16 2003-12-15 multipath-009
17 * Make the HW-specific get_unique_id switch pretty
18 * Prepare to field-test by whitelisting all known fibre array,
19 try to fetch WWID from the standard EVPD 0x83 off 8 for everyone
20 * configure the multipath target with round-robin path selector and
21 conservative default for a start (udm1 style) :
22 yes it makes this release the firstreally useful one.
23 * temporarily disable map creation for single path device
24 due to current restrictive defaults in the kernel target.
25 Sistina should work it out.
26 * correct the strncmp logic in blacklist function.
27 * update the Makefiles to autodetect libgcc.a & gcc includes
28 "ulibc-style". Factorisation of udevdirs & others niceties
29 * drop a hint about absent /dev/sd? on failed open()
30 * implement a reschedule flag in /var/run.
31 Last thing the prog do before exit is check if a call to multipath
32 was done (but canceled by /var/run/multipath.run check) during its
33 execution. If so restart themain loop.
34 * implement a blacklist of sysfs bdev to not bother with for now
35 (hd,md, dm, sr, scd, ram, raw).
36 This avoid sending SG_IO to unappropiate devices.
37 * Adds a /var/run/multipath.run handling to avoid simultaneous runs.
38 * Remove a commented-out "printf"
39 * drop a libdevmapper copy in extras/multipath;
40 maybe discussions w/Sistina folks will bring a better solution in the future.
41 * drop a putchar usage in libdevmapper to compile cleanly with klibc
42 * drop another such usage of my own in main.c
43 * massage the Makefile to compile libdevmapper against klibc
44 * use "ld" to produce the binary rather than "gcc -static"
45 * stop being stupid w/ uneeded major, minor & dev in main.c:dm_mk_node()
46 * reverse to creating striped target for now because the multipath target
47 is more hairy than expected initialy
48 * push the version code to 009 to be in synch w/ udev
49 2003-11-27 multipath-007
50 * removes sg_err.[ch] deps
51 * makes sure the core code play nice with klibc
52 * port the sysfs calls to dlist helpers
53 * links against udev's sysfs (need libsysfs.a & dlist.a)
54 * finally define DM_TARGET as "multipath" as Joe posted the code today (not tested yet)
55 * push version forward (do you want it in sync with udev version?)
57 * merged in udev-006 tree
58 2003-09-18 Christophe Varoqui <christophe.varoqui@free.fr>
59 * multipath 0.0.1 released.
