Re: strange disk access
I checked my logs and noticed nothing out of the ordinary routine anywwhere.
At the time I did as you recommend to run top and ps but my system was
operating so poorly all I got to see was a sad load average of 3+
during all the chaos in GNOME...
Thanks a lot for recommending atop, it looks like a really good tool.
Although I still need to install the 'cnt' patch to my 2.4 kernel so I
can track disk and network activity on a per process basis with it. I
do not have any experience doing this so it should be fun learning. Any
quick pointers for good tutorials or howtos on debian kernel upgrading
etc would be appreciated.
Thanks for the replies

Hi Bart,
my first guess is a cron job. So I'd look in the /etc/cron.* directories
(if I knew the time of the disk access). Also in 1.5 minutes, there is
plenty of time to start 'top' or 'ps' to see the processes acting up.
And finally there is 'atop', which records the running processes. CPU
usage etc for later perusal. So you can just let it run and examine what
happened later.
