I have no idea. I can't see how they would be able to do it with RAID5, unless
grub or whatever bootloader RedHat uses is MUCH smarter than I give it credit for.

If you can't get it to boot, when your /boot is just a normal partition, then
you should probably look elsewhere for a problem.

If you include your bootup messages, it would be much easier to figure out what
goes wrong.

You could also include the output of "cat /proc/mdstat" and "mount", when your
system is bootet with the redhat kernel.

Re: Last ditch effort for RH9 and LSR0

[Brennahn Chesteine]

Well I remember that I could not make my boot
partition RAID 0. That kinda ticked me off. You have
to understand, in my infiniate wisdom I purchaced a
Silicone Image ATA RAID card :( Yeah, stupid huh?

Has anyone ever used Vector Linux? I have it on my
laptop a 300 celery and it's ALOT lighter than RH,
wich I like. 

Is there a chance in heck that I could set up a
software RAID0 "root" parition before I install this
distro "Vector", then do the install? I have always
been able to install RH then rebuild X the WM and
kernel to my likeing but this has got me to a point to
where I will be up for learning something new. 

As for the RAM I have 512 but in order to install
Linux  on the main boxen I have to keep WinXP booted
in VMware ALWAYS for the woman so she can use the P.C.
Small price to pay in my opinion.

but where can I find my boot error messages? I have
checked /ver/log/boot but it never has info about my
failed startups.


Thanks for the help thus far !

Last ditch effort for RH9 and LSR0

[Brennahn Chesteine]

I am at my witts and with trying to install a new
kernel under RH9. My system is set up with "root" and
"swap" in LSR0 and "/boot" in LSR5. I have taken all
know suggestions to get 2.4.20 to boot but nothing
after a month. 

I was wondering if anybody had managed to install a
new kernel under RH8or9 with a similar configuration.
And if so could they save there current config to a
file and shoot it this way so I can see what the heck
I am doing wrong. 


thanks for all the help thus far!

If you by LSR5 mean Linux software RAID5, I'm not surprised it isn't working. 
You can't boot from a software RAID5 on Linux. To do that, lilo would have to 
know how to pull different data chunks from different drives.
/boot on RAID1 works because RAID1 puts the same data on both drives.
