[NTLUG:Discuss] Debian Web Server Error

[Dennis Myhand]

I have built a web server using Debian Lenny as a test box to set up 
some different types of websites using LAMP, this being for my school 
and for my hardware class students.  Lately I have been having trouble 
accessing the webmin interface (I have a installed a blog, a forum, a 
moodle install, a Mambo install, and webmin to show my students what can 
be done with simple hardware and Open Source/Free Software) to manage 
the sites.  I shut down today when this happened and logged the 
following error:

[808804.8566641] end_request: I/O error, dev sda, sector 13533247
(this went on line upon line for over three hours when I tried to shut down)

I looked this up on the intarwebs and found a site which advised doing 
the following:

dmesg | grep sda > dmesg.txt

Below is the output of that command string.  I take it I have a hard 
drive failing.  From the 40021MB in parentheses am I safe in guessing 
that this is my 40gig root partition and not the /var or /home 
partitions I have set up on separate 80gig drives?  Thanks, Dennis
