Public bug reported:
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.
