View Full Version : Stop FC6 from installing with multipath

8th January 2007, 09:55 AM
Hello everyone.

I have had FC on my trusty server since I first came across linux with FC3. Each time a new release came out I performed an internet upgrade without hassle.

I have recently swapped some HDDs out of my desktop and decided to upgrade my server and do a full re-install. This is where I am now - first I will describe my setup.

HP Vectra VL400
Geforce 4 MX440 64MB
Adaptec 29160 SCSI controller (PCI)
SCSI0 Atlas 10k3 36GB
SCSI1 Atlas 10k3 36GB

The installer presents the 120GB IDE drive ok, but represents the SCSI drives as a single ~34GB drive labelled as mapper/mpath0

I wanted to install /boot to a 100MB part on the 120GB, with / and /swap installed to a linux RAID1 on the pair of SCSI drives. The remainder of the 120GB would be mounted as /storage.

Is there any way of preventing the installer from what looks like multipathing my two SCSI drives, and present them as they should be.. /dev/sda and /dev/sdb?

I have tried adding 'linux askmethod nodmraid' at the command line but no change. (askmethod as I have the images on a USB HDD).

Anyone? Is there somewhere more appropriate to ask this question?

OK I have installed solely to the IDE drive and have the server up. Does anyone happen to know how to disable multipath support once running? If I can diasble it I will then partition as I want them and transfer / and /swap over.
