Disk thrashing in Ubuntu Gutsy

Problem:

Disk thrashing (excessive disk i/o) causes decrease/loss of responsiveness in Ubuntu Gutsy.

Solution:


The thrashing was caused by the swap not being turned on properly.



The swap was not turned on because fstab had the wrong UUID.Fixed based on instructions here: http://ubuntuforums.org/showthread.php?p=3704872



- type

Code:

blkid

- note the UUID of the partition that should be the swap

- edit /etc/fstab so that the UUID matches

System Details:
Compaq Presario R3000, nVidia video card, Ubuntu Gutsy 7.1
