[gentoo-user] SATA & USB SCSI drives...

[Sieb, Glenn E (Glenn)]

Hi everyone..

Running 2006.0, 2.6.15-r5 kernel

1U box, SATA boot drive (sda), and an attached USB drive (in theory, sdb) for on-site backup storage. 

Problem is--if the USB drive is plugged into the system when it reboots, the *USB drive* comes up as sda.

Somehow I doubt changing /etc/modules.autoload.d/kernel-2.6 is going to fix this.

I doubt using udev rules is going to fix this, either--as, frankly, the system has to be able to boot in order to read them.

Is there any way of getting the USB drive to *not* mount as sda? Ever? :-\ :-/

Thanks in advance,
Best,
--Glenn

Build USB support as modules, then they won't be available until after
the root filesystem is mounted and udev is started.

At that point, use udev rules to fix the USB drive's device node to
something less generic...like /dev/backups.

You could try building USB suport as a module that would autoload during the
auto loading modules phase, then you wouldn't have USB support right away
and the sata drive should be sda all the time

And that was the magic brain unblocker. :) Thanks, Richard!
