Title:
  jbd2/dm-* constant io, filling hard disk

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  My hardware at a glance:

  AMD A10 5800k
  ASRock FM2A75-DGS
  4 GB DDR3 1866
  250 GB SATA II HD ST3250318AS
  64 GB OCZ Vertex-4

  Software is Ubuntu 12.10 x64, stock kernel version 3.5.0-21-generic

  I have my /home partition residing on the 250 gb drive, and it stays
  almost always full, which is why I've probably been able to notice
  this bug so quickly.  I was getting warnings about my disk getting
  full, and I thought it odd since I haven't moved any files around
  lately.  iotop shows the command [jbd2/dm-0-8] and [jbd2/dm-2-8]
  writing to my disk about every 10 seconds, and it writes about 50 KB
  each time, to a location I can't seem to find.  It's filled up a few
  GB of space today alone, and I fear that it may be overwriting,
  instead of filling up empty space that isn't there!

  I am sure that the problem only started somewhat recently.  If any
  other logs or info would help, let me know what to post.
