Hi allAfter several days of investigation, I am still not sure what is causing the problem. I have noted the following: The journaling program jbd2/sda1-8 is taking up most of the I/O time. I do have noatime set in fstab. Having two identical machines is very helpful. My wifes system is fast and never bogs down. Mine is a real dog at this time. I ran iotop on both systems. In my wifes kjournal will pop to the top of the list for a very short period when loading a new application. Otherwise iotop is quiet. On mine kjournal doesn't show at all but jbd2/sda1-8 shows up all of the time. There is constant activity on my system even when nothing is happening. Below is the output from gsmartcontrol. Note that vendor specific attributes 197 and 198 raw values are 757 and 232 respectively and are highlighted in pink on the gsmartcontrol program. My wifes computer's raw values are included in the last column of the smart attributes table for comparison. Also note that there were no errors reported for my wifes system. Do I need to replace the drive or is this fixable. Is this even the root cause of my problems. I'm not too sharp on reading this data an will appreciate comments from a more knowledgeable person. smartctl 5.41 2011-06-09 r3365 [x86_64-linux-3.2.0-4-amd64] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Model Family: Western Digital Caviar Green Device Model: WDC WD5000AADS-00M2B0 Serial Number: WD-WCAV59765616 LU WWN Device Id: 5 0014ee 25992fc38 Firmware Version: 01.00A01 User Capacity: 500,107,862,016 bytes [500 GB] Sector Size: 512 bytes logical/physical Device is: In smartctl database [for details use: -P show] ATA Version is: 8 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Sun Sep 28 18:12:56 2014 PDT SMART support is: Available - device has SMART capability.
