[Bug 1639744] Re: lsblk does not use extended WWNs and may return the same ID for two different disks

[Steffen Neubauer]

would like to see a backport of https://github.com/karelzak/util-
linux/commit/3b94a098b04c581be353e71a212a6964b53dd640 for xenial as
well, is there a way to help?

Title:
  lsblk does not use extended WWNs and may return the same ID for two
  different disks

Status in util-linux package in Ubuntu:
  Confirmed

Bug description:
  lsblk from util-linux in xenial is affected by this bug:
  https://github.com/karelzak/util-linux/issues/321

  This means that lsblk may return the same identifier for different
  devices, because it always uses the short WWN, while some devices are
  only identified uniquely by the full (extended) WWN.

  This has been fixed in upstream util-linux for a while, but the
  version in xenial is just a tick too old. Since the patch is less than
  10 lines, maybe you would consider a backport?

  To my knowledge, this affects mainly "Enterprise" hardware - logical
  volumes on fully hardware-driven RAID controllers like HP, Dell,
  LSI/Avago, and logical volumes on external storage arrays addressed
  over iSCSI or FC.
