Still problems with USB

Still problems with USB

[Clemens Eisserer]

First of all a big thank you for your fast replies the tipp with the usb-subsystem loading time.
Thanks to some tutorials I got this working (just create an initrd that preloads the usb/scsi subsystems.

However I now have another strage problem:
1.) When booting up my USB hd is detected before raid is initialized.
2.) The MD Driver tells me that it can only find /dev/sda1 of the array, although all partition-types are set correctly ("fd"). Please have a look at the dmesg-output I atached.
3.) Mout tells me, that /dev/md0 is mounted on "/" - in /etc/fstab there is only written something like /      $LABEL (or something like that - I think it has something todo with grub, dont know if it was called LABEL).
4.) If I write data to / only my internal harddisk (/dev/hda3) is involved, althought / is /dev/md0 (accoring to mount) and the raid-driver told me that only /dev/sda1 (usb) is used.
5.) If I do hdparm -tT /dev/md0 only my usb-drive is benchmarked.
6.) If I ask /proc/mdstat it also tells me that only /dev/sda1 is aktive.

Does anybody have an idea whats going wrong. I am quite confused :-(
I am more and more playing with the thought  that I just a small partition as root-partitions and symlink /usr and /opt to my raid. Would that make sence and would it hurt the performance much?


I know such newbie questions are nerving, but I played with raid for now several hours and I really don't see any way to procees any further thats why I am bothering you.

Thanks in advance and sorry for creating so much traffic.

Re: Still problems with USB

[GrantC]

Hi Clemens,

I've been working with software RAID0 a fair bit recently, so this 
is on topic for me.

On Wed, 16 Feb 2005 17:35:54 +0100, you wrote:

What you are doing is not making any sense at all, the machine needs 
to boot all by itself -- trying to run an OS with half of it hanging 
on a removable drive on USB transport strikes me as being a very bad 
idea.  

>I am more and more playing with the thought  that I just a small partition as root-partitions and symlink /usr and /opt to my raid. Would that make sence and would it hurt the performance much?

Makes no sense at all to me.  Using RAID1 hurts performance, write 
everything twice, and the read performance boost is not impressive, 
but my benchmarking was on a much slower system.

Please trim it next time!

     ^^^^^^^^^^^^^^^^^^^^^^^^^-- I've not seen these before
"Use the source, Luke":

linux-2.6.10/drivers/md/md.c
/*
 * prevent the device from being mounted, repartitioned or
 * otherwise reused by a RAID array (or any other kernel
 * subsystem), by bd_claiming the device.
 */

I don't like grub either, it has done strange things to me, LILO is 
old and very reliable.

This is what I'd expect to see.  The RAID1 is broken.  What you 
are doing is technically broken IMHO, or simply not what I would 
consider doing.  Funny thing is I recently put a larger HDD into 
my laptop, and bought a USB adaptor for the old 6GB HDD -- but 
the thought of RAIDing a portable hard drive never occured to me.

Not trying to discourage you from playing though, as that is how 
to learn...

Cheers,
Grant.
