[Bug 1099600] Re: jbd2/dm-* constant io, filling hard disk


Kyle Bentley, as per http://www.asrock.com/mb/AMD/FM2A75M-DGS/?cat=Download&os=BIOS an update is available for your BIOS (2.60). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see

Thank you for your understanding.

  jbd2/dm-* constant io, filling hard disk

Status in “linux” package in Ubuntu:

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.
