Re: Degrading disk read performance under 2.2.16

Sheesh you have to at least turn on in the kernel at compile time to attempt dma. Maybe using the chipset tuning code to get it programmed correctly, would get you to the average 22MB/sec that piix and drive combo will do. On Fri, 11 Aug 2000, Corin Hartland-Swann wrote: > > Mark, > > I'm cr

Mark, I'm cross-posting this to the kernel and RAID lists again, because there's more information about the problem in here. I hope this is acceptable. On Thu, 10 Aug 2000, Mark Hahn wrote: > > Intel 810E Chipset Motherboard (CA810EAL), Pentium III-667, 32M RAM, > > Maxtor DiamondMax Plus 40 40

Yeah, it's in there. I was blowing past that before... My mistake. Thanks for the help. -- On Aug 11 at 14:32, Nick Kay (nick) wrote: > Subject: Re: How do I tell the kernel I want RAID-5? > > At 09:12 11/08/00 -0400, you wrote: > >This is going to sound pretty stupid, but here goes anywa

lilo issue

Hi all, I have my raid-1 up and running over two 9gig scsi drives under slackware 7.1 with kernel 2.2.16+raid-2.2.6-AO from Ingo and lilo-21.5. After disconnecting the second drive (ID 1) and rebooting works fine, however pulling ID0 causes problems in that lilo comes up without an

How do I tell the kernel I want RAID-5?

This is going to sound pretty stupid, but here goes anyway... I got 2.2.16 and the latest patch from kernel.org, applied it and started to rebuild. The question is, where do I tell the kernel to use RAID-5? I can't see it in the 'make menuconfig' stuff anywhere... Am I missing something here?
