can't change the value of /proc/sys/vm/low_io_sectors and high_io_sectors

[richeal75]

Hello ,

I can find "low_io_sectors" and "high_io_setcotrs" in /proc/sys/vm after i upgrade kernel from 2.4.9-e3 to 2.4.9-e62

and then I adjust them as below:

echo 2000 /proc/sys/vm/low_io_sectors
echo 4000 /proc/sys/vm/high_io_sectors

and then result is ok as below

2000 /proc/sys/vm/low_io_sectors
4000 /proc/sys/vm/high_io_sectors

and I run " more /proc/sys/vm/low_io_sectors"
but I find the value is not changed

why ?

you commands are wrong:

# echo 2000 >/proc/sys/vm/low_io_sectors
# echo 4000 >/proc/sys/vm/high_io_sectors

you forget the '>' !

ciao
