Hello
IOnice only works with CFQ, have you checked that you are using the CFQ IO scheduler? # cat /sys/block/hda/queue/scheduler #put the name of YOUR harddisk
In case it's not the default IO scheduler, you can change it with: # echo cfq > /sys/block/hda/queue/scheduler
My two cents... See you, Eric
