[ANNOUNCE] multipath-tools-0.2.7

[christophe.varoqui]

Hello,

here goes multipath-tools version 0.2.7

Jan,
the ULUA framework I got implemented is rather simple :
1) the path struct gets a new ->priority member
2) before path grouping, sort the path list by priority

The missing link is the priority fetcher.
Does that framework fit your needs ?

2004-07-24 multipath-tools-0.2.7
        * [multipath] args parser moved to getopt
          <genanr@emsphone.com>
        * [multipath] zero conf->hotplugdev at allocation
          <genanr@emsphone.com>
        * [multipath] clean up failed devmap creation attempt
        * [libs] update to libdevmapper 1.00.19
        * [multipath] framework for claimed device skipping
          still lacks a reliable way to know if the device is
          claimed and by who (fs, swap, md, dm, ...). If you
          think it is valid to let libdevmapper hit the wall,
          please speak up and tell so.
        * [multipath] shut down stderr when calling into libdm
        * [multipath] reformat the verbose output
        * [multipath] framework for path priority handling (ULUA)
        * [multipath] kill all reference to group_by_tur
        * [multipath] integrate path state logic into multibus &
          failover pgpolicies. This obsoletes the group_by_tur one
          which is now the same as multibus.
        * [multipath] zalloc mp structs to avoid garbage in ->size
        * bump version requisite for scsi_id to 0.6 to support the new
          '-u' flag (s/ /_/ for proper JBOD device map naming)
        * [multipath] correct the for(;;) limits to accept 1-slot
          pathvecs
        * [multipath] push WWID_SIZE to 64 char (scsi_id w/ JBODs)
        * [multipath] add a exit_tool() wrapper fn for runfile unlink
        * [multipath] add a "default_path_grouping_policy" keyword in the
        * "defaults" block.
        * [multipath] add a "default_getuid_callout" keyword in the
          "defaults" block. Now multipath is going to work with JBODs
        * [multipath] fix segfault when pathvec is empty after
          get_pathvec()
        * move to template based specfile to avoid regular version skew

Note, that I see this ->priority as a generic way to deport path grouping policy
into callout binaries : I'll code a generic "group_by_prio" pgpolicy and a
priority_callout config keyword for that.

[ANNOUNCE] multipath-tools-0.2.8

[christophe varoqui]

Hello,

here goes multipath-tools version 0.2.8

This is pre-vacation release, to sync up with guys working with the
priority framework.
I'll be mostly off till Sept 1st.

Reported build breakage on IA64 is not solved in this release. I don't
have the hw to investigate this. If someone is interested, feel free to
debug this and send a patch. The breakage seem to come from the clone
syscall declaration.

Todo, for next releases :

* move to the new klibc development environment Sam Ravnborg is working
on, as soon as it stabilizes : hope to drop the klibc tree from the
multipath-tools tarball, and finally be packageable by distributors.

* resolve the OOM scenarii for multipathd. I guess the kernel will have
to help in some way. Anyway, advice badly needed here.

2004-08-14 multipath-tools-0.2.8
        * [multipathd] setsched prio to RT
        * [multipath] massive include cleanup
        * [multipath] add a "default_prio_callout" keyword
          first user will be SPC-3 ALUA priority field fetcher
          from IBM
        * [multipath] reenable stdout on some error paths
        * [build] spilt KERNEL_DIR into KERNEL_SOURCE &
          KERNEL_BUILD as per 2.6 and SuSe convention
        * [klibc] kill warnings due to awk parsing wrong locale in
          arch/i386/MCONFIG
        * [multipath] implement a generic group_by_prio pgpolicy
        * [multipath] fix the broken failover pgpolicy
