[Bug 1296305] Re: The multipath-tools package in Ubuntu doesn't have the libprioweightedpath.so and the libprioiet.so modules

[Robie Basak]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

As far as I can determine, the features you mention are new in 0.5.0-1,
which was only uploaded to Debian on 9 March this year. This is after
feature freeze for Trusty, so it is unlikely to be released in Ubuntu in
Trusty, but I expect that it will make a future release.

It seems that the version available in Debian wheezy was by picking up
git snapshots, which has not been the case in Ubuntu.

To determine this, I searched the sources for filenames matching
*weight*. I see this in wheezy and sid, but not in Trusty. The version
numbers tell the rest of the story.

I'm marking this bug Invalid, since it doesn't seem to me to be a bug
that an older release doesn't have a newer feature. See
https://wiki.ubuntu.com/StableReleaseUpdates and
https://wiki.ubuntu.com/UbuntuBackports for Ubuntu policy around these
issues.

However, you should see these features in a future release (post Trusty)
after the newer upstream release is merged from Debian after Trusty's
release. If you wish, you can file a "please update to latest release"
bug, or convert this bug to such a bug, but since we're past feature
freeze for Trusty, nothing is likely to happen until the U release.

Title:
  The multipath-tools package in Ubuntu doesn't have the
  libprioweightedpath.so and the libprioiet.so modules

Status in “multipath-tools” package in Ubuntu:
  Invalid

Bug description:
  In the multipath-tools upstream, there is a prioritizer called
  weightedpath.

  See: http://git.opensvc.com/?p=multipath-
  tools/.git;a=blob;f=libmultipath/prioritizers/weightedpath.h;h=509f21565d06d8c10a0f0a79756195a5583125d8;hb=HEAD

  This prioritizer exists in some distribuction specific pre-compiled
  packages too, like in Debian Wheezy.

  See: https://packages.debian.org/wheezy/amd64/multipath-tools/filelist

  However, this prioritizer doesn't exist in any Ubuntu version, as we
  can see in the following links:

  - http://packages.ubuntu.com/trusty/amd64/multipath-tools/filelist
  - http://packages.ubuntu.com/precise/amd64/multipath-tools/filelist

  Since this module can be very useful, why don't the Ubuntu maintainers
  provide it? Is there any special reason?

  ----

  The Debian package also has the iet prioritizer (file
  /lib/multipath/libprioiet.so). This prioritizer may be used to solve
  common problems too.

  This module doesn't exist in any Ubuntu package too.

  I created this bug report because someone suggest me in the question
  #245910:

  I suggest you report a bug. If you feel something is missing then you
  flagging it up may get it added.
