[Bug 1789786] Re: SRU ledmon into Bionic

[Łukasz Zemczak]

Hello Woodrow, or anyone else affected,

Accepted ledmon into bionic-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/ledmon/0.90-0ubuntu1~18.04.1 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  SRU ledmon into Bionic

Status in ledmon package in Ubuntu:
  Fix Released
Status in ledmon source package in Bionic:
  Fix Committed

Bug description:
  [Impact]
  The support for Intel VROC technology requires both kernel and userspace components. The kernel components have landed in 4.14 and are available in Bionic. In order for users to take advantage of VROC in their deployments, the following userspace packages are also needed in Bionic:

  ledmon - Enclosure LED Utilities
  Upstream project: https://github.com/intel/ledmon

  mdadm - tool to administer Linux MD arrays (software RAID)
  Upstream project: https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/

  This SRU is about ledmon; it is being handled in bug #1668126.

  This SRU falls under the hardware enablement category.

  [Test Case]
  1.Install mdadm and ledmon
  $ sudo apt install mdadm ledmon

  2.Follow the instruction to create a RAID0/1/10 volume from Intel HII,
  referm https://goo.gl/xwqqDs

  3.Make sure RAID already reassembled or not
    $cat /proc/mdstat
    $mdadm --detail-platform
    $mdadm --detail /dev/md12*
    $mdadm --detail /dev/md12*

  4.Try to partition or mount /dev/md126

  5.Use fio package to do performance test.

  More detailed testing can be executed if the appropriate hardware is
  available.

  [Regression Potential]
  The performance issue may be met under specific hardware with VROC support; We have to make the SRU work then we can explore more things further under bionic.
