[Bug 1313784] Re: File descriptors leaked on lvs invocation

[Colin Watson]

This is largely pointless whining from the lvm tools and is entirely
cosmetic.  At some point we should dig out the environment variable that
suppresses this and have GRUB pass it.

** Package changed: grub-installer (Ubuntu) => grub2 (Ubuntu)

** Changed in: grub2 (Ubuntu)
   Importance: Undecided => Low

** Changed in: grub2 (Ubuntu)
       Status: Confirmed => Triaged

Title:
  File descriptors leaked on lvs invocation

Status in grub2 package in Ubuntu:
  Triaged

Bug description:
  While upgrading to Kubuntu 14.04 yesterday, I got the following error
  messages over and over again:

  Generating grub configuration file ...^M
  File descriptor 3 (pipe:[4852522]) leaked on vgs invocation. Parent PID 6438: grub-probe^M
  File descriptor 59 (/var/log/dist-upgrade/apt.log) leaked on vgs invocation. Parent PID 6438: grub-probe^M

  
  The file descriptors appeared random, and the "Parent PID" was either /bin/sh, grub-install, grub-probe or /usr/sbin/grub-probe:
  grep leaked ./dist-upgrade/apt-term.log |sed 's/.*Parent PID [0-9]*: //' | sort  | uniq -c
       53 /bin/sh
       72 grub-install
      106 grub-probe
     1484 /usr/sbin/grub-probe
