2 * check hotplug event refers to a block device; if not exit early
4 * add the uninstall target in Makefile
5 2003-12-22 multipath-010
6 * tweak the install target in Makefile
7 * stop passing fds as argument : this change enable a strict
8 segregation of ugly 2.4 code
9 * sysfs version of get_lun_strings()
10 * be careful about the return of get_unique_id() since errors
11 formerly caught up by if(open()) in the caller fn are now returned
13 * send get_serial() in unused.c
14 * introduce dm-simplecmd for RESUME & SUSPEND requests
15 * split add_map() in setup_map() & dm-addmap()
16 * setup_map() correctly submits "SUSPEND-RELOAD-RESUME or CREATE"
17 sequences instead of the bogus "RELOAD or CREATE"
18 * don't print .sg_dev if equal to .dev (2.6) in print_path()
19 * since the kernel code handles defective paths, remove all
20 code to cope with them :
21 * move do_tur() to unused.c
22 * remove .state from path struct
23 * remove .state settings & conditionals
24 * add a cmdline switch to force maps to failover mode,
25 ie 1 path per priority group
26 * add default policies to the whitelist array (spread io ==
27 MULTIBUS / io forced to 1 path == FAILOVER)
28 * move get_disk_size() call out of add_map() to coalesce()
29 * comment tricky coalesce() fn
30 * bogus unsused.c file renamed to unused.c
31 2003-12-20 multipath-010
32 * big ChangeLog update
33 * start to give a little control over target params :
34 introduce cmdline arg -i to control polling interval
35 * cope with hotplug-style calling convention :
36 ie "multipath scsi $DEVPATH" ... to avoid messing with
37 online maps not concerned by an event
38 * example hotplug agent to drop in /etc/hotplug.d/scsi
39 * revert the run & resched patch : unless someone proves me
40 wrong, this was overdesigned
41 * move commented out functions in unused.c
42 * update multipath target params to "udm[23] style"
43 * mp target now supports nr_path == 1, so do we
44 * add gratuitous free()
45 * push version forward
46 2003-12-15 multipath-009
47 * Make the HW-specific get_unique_id switch pretty
48 * Prepare to field-test by whitelisting all known fibre array,
49 try to fetch WWID from the standard EVPD 0x83 off 8 for everyone
50 * configure the multipath target with round-robin path selector and
51 conservative default for a start (udm1 style) :
52 yes it makes this release the firstreally useful one.
53 * temporarily disable map creation for single path device
54 due to current restrictive defaults in the kernel target.
55 Sistina should work it out.
56 * correct the strncmp logic in blacklist function.
57 * update the Makefiles to autodetect libgcc.a & gcc includes
58 "ulibc-style". Factorisation of udevdirs & others niceties
59 * drop a hint about absent /dev/sd? on failed open()
60 * implement a reschedule flag in /var/run.
61 Last thing the prog do before exit is check if a call to multipath
62 was done (but canceled by /var/run/multipath.run check) during its
63 execution. If so restart themain loop.
64 * implement a blacklist of sysfs bdev to not bother with for now
65 (hd,md, dm, sr, scd, ram, raw).
66 This avoid sending SG_IO to unappropiate devices.
67 * Adds a /var/run/multipath.run handling to avoid simultaneous runs.
68 * Remove a commented-out "printf"
69 * drop a libdevmapper copy in extras/multipath;
70 maybe discussions w/Sistina folks will bring a better solution in the future.
71 * drop a putchar usage in libdevmapper to compile cleanly with klibc
72 * drop another such usage of my own in main.c
73 * massage the Makefile to compile libdevmapper against klibc
74 * use "ld" to produce the binary rather than "gcc -static"
75 * stop being stupid w/ uneeded major, minor & dev in main.c:dm_mk_node()
76 * reverse to creating striped target for now because the multipath target
77 is more hairy than expected initialy
78 * push the version code to 009 to be in synch w/ udev
79 2003-11-27 multipath-007
80 * removes sg_err.[ch] deps
81 * makes sure the core code play nice with klibc
82 * port the sysfs calls to dlist helpers
83 * links against udev's sysfs (need libsysfs.a & dlist.a)
84 * finally define DM_TARGET as "multipath" as Joe posted the code today (not tested yet)
85 * push version forward (do you want it in sync with udev version?)
87 * merged in udev-006 tree
88 2003-09-18 Christophe Varoqui <christophe.varoqui@free.fr>
89 * multipath 0.0.1 released.
