[Bug 872217] Re: diskstats plugin: error "Byte order is not compatible"

[Daniel Holbach]

Thanks for your work on this. I took the liberty of making the following modifications:
 - update the changelog to base on the newest version
 - use 'edit-patch' to get the patch into a format the patch system (quilt) understands
 - add some description to patch file.

Uploading it right now. As we're in Beta Freeze, it might sit in the
review queue for a bit.

Title:
  diskstats plugin: error "Byte order is not compatible"

Status in Munin:
  Fix Released
Status in “munin” package in Ubuntu:
  Fix Committed

Bug description:
  The diskstats plugin fails to provide any data since a while:

      % sudo munin-run diskstats
      Byte order is not compatible at ../../lib/Storable.pm (autosplit into ../../lib/auto/Storable/thaw.al) line 415, at /etc/munin/plugins/diskstats line 120

  Line 120 mentioned in the error is the second line of the following
  return value in the function choose_old_state:

      return $return_timestamp,
        %{ thaw decode_base64 $states{$return_timestamp} };

  I assume that upgrading from Ubuntu Natty to Oneiric might have caused
  this?!

  I am using munin 1.4.6-1ubuntu1 currently, which has not made it into
  Ubuntu though yet (merged from Debian by myself).

  WORKAROUND:
  sudo rm /var/lib/munin/plugin-state/diskstats-*
