I have a Fedora 11 server running 2.6.30.9-96.fc11.x86_64. I
recently
noticed that my hard drive light is on constantly and was wondering how I
can determine what is accessing the hard disk so much. After boot the hard
disk is acting normally for a few minutes to a few hours and then the hard
drive light is lit up constantly.
I have tried ps -ef to see if there was anything running that I do not know
about and there is not. Is there any way for me to determine which process
is consistently using the hard disk?
Yep,
# yum install iotop
# iotop
Recent kernels include per-process IO accounting, so you should be
able to tell what is waking up your disk by watching the iotop output.
