Hi folks,
I have an HP Proliant 140DL G2 server with what appears to be an IDE
drive in non-DMA mode. Performance on the server is extremely bad
when large amounts of disk activity is taking place.
I think the problem is that my drive is not in DMA mode:
# hdparm /dev/hda
This should be /dev/sda and not /dev/hda which means you're most likely
using the generic-ide driver and not ata-piix.
Google suggests booting with ide0=noprobe ide1=noprobe to make sure the
ata-piix driver is used.
If you don't want to reinstall then make sure initrd contains the
ata-piix driver and that references to /dev/hd* are replaced with
/dev/sd* in fstab etc.
