Pete Goodall (pgoodall) wrote : massive i/o renders the system unusable

Periodically I notice my system slows to a near stand still, and the hard drive light is constantly going. This seems to be a massive amount of disk i/o and it lasts for a long time (lets say 30 mins to put a number on it). I installed and ran iotop (`iotop -a`) and it seems to point to jbd2. From what I can see jbd2 is related to ext4 journaling, but I cannot figure out how to kill this operation. It might even be a red herring because I have also stopped the disk activity by kill either chromium or firefox. I need to understand what else I can do to troubleshoot this.
