 |

Hi!
If your hard disks start at /dev/hde or higher (for example UltraATA100),
and you use the 2.4.x kernel, you should get something like this when you
look in /proc/stat:
| Code: |
bazik@antares bazik $ cat /proc/stat
cpu 633 0 1088 9286
cpu0 633 0 1088 9286
page 27641 128
swap 1 0
intr 19998 11007 529 0 0 0 0 2 0 0 1026 2427 4997 0 0 0 10 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Important is the "disk_io:". As you can see, its empty here... and thats a known issue with the 2.4.x kernel and "high" devices.
I found this out because GKrellM didnt show a "disk" option for me. It was
simply blank. BTW, this solution here is also mentioned in the FAQ on the GKrellM homepage.
To solve this problem, you need to patch your Kernel. First download the
correct patch from http://www.swanson.uklinux.net/
Then goto /usr/src and patch your Kernel tree. I have the 2.4.18-xfs sources.
| Code: |
root@antares src # patch -p0 < /home/bazik/MyFiles/patch-diskio-2.4.18-1
|
If it complains file not found, you propably need to edit the paths in the patch because it says "linux-2.4.18" sometimes. Or simply make a symlink 
After patching, just recompile your Kernel, replace the old and reboot.
Then do a cat /proc/stat again and it should look like this:
| Code: |
bazik@antares bazik $ cat /proc/stat
cpu 7302 0 1883 66962
cpu0 7302 0 1883 66962
page 48977 1376
swap 1 0
intr 149055 76147 4471 0 0 0 0 2 0 0 9742 3997 54686 0 0 0 10 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
disk_io: (33,0):(4011,3290,106451,721,12853) (33,1):(1,1,8,0,0) (34,0):(1,1,8,0,0)

As you can see, after patching it reports "disk_io:" now. GKrellM is working now, too
Hope this helps someone!
