RAID no worky with 2.2.16...
Crash
setup a linear RAID over two IDE drives that did exactly what I wanted to
before I upgraded kernels.
It was working fine with 2.2.14 (the kernel bundled with RedHat 6.2).
Then I upgrade to 2.2.16 and it won't work at all.
Whenever I try to do a "raidstart -a", I get a:
/dev/md0: Invalid argument
That's it. There's nothing pertinent in /proc/mdstat , or in the syslog.
I didn't change /etc/raidtab at all when I upgraded the kernel. I
configured the kernel for linear RAID support.
I remember the same thing happening when I tried to upgrade to 2.2.15, so
I just stuck with 2.2.14. So I doubt it's a problem specific to 2.2.16.
I do know this, though: Whenever I booted with RedHat's 2.2.14 kernel, I
always saw a message about "selecting fastest RAID method" (or something
like that--you know what I'm talking about if you have RedHat 6.2). That
doesn't happen with 2.2.16.
Anyway, I'd appreciate any help I might recive on this matter; I've got a
lot of data that's offline that I need access to!
Thanks

Maybe these will help.

I mean: you upgraded to a standard kernel, and it is OK. BUT, to use RAID
you'd read the RAID-HOWTO and then you'd discover that the standard kernel
doesn't work. You need to patch the standard kernel to get RAID tools up
and running.
RedHat provides an already patched kernel which supports RAID, so they
have already done the patching work for you and you don't know nor notice
anything "special".
Now, problem is, I've been to kerneli.org this weekend, and there were
no RAID kernel patches for kernels after 2.2.11. Therefore I guess RH
rolled their own for 2.2.14 and put it on their CD. So, AFAIK there are
no later patches and you are stcuk with latest RH stock kernel. Am I wrong?
If anyone knows of RAID kernel patches for later kernels I'd be most glad
to know. Also, on the 2.2.14-RH patched kernel I keep getting long lists
of ficticious SCSI devices that I can't avoid on startup no matter which
config options I use, and I have great trouble making it work with an HP
CD writer.
Please, if you know a workaround, let me know also by e-mail, I'll be
on a trip this week and won't be able to monitor the newsgroup.

These opinions are mine and only mine. Hey man, I saw them first!

Thanks for the reply.
I did read that HOWTO before I even upgraded, but I noticed that it was
several months outdated so I assumed that the newer 2.2.x kernels had that
patch built in. That and I, like you, noticed that the latest RAID patch
even availiable was for 2.2.11.
However, I just now ran across the "correct" patches. They're at:
http://people.redhat.com/mingo/raid-patches/
Looks like patches from 2.2.14 to 2.2.16 . Haven't tried them yet, so I
can't give you any success stories yet, but it appears to be what you and
I are looking for.
Hope this helps.

Also make sure the upgrade didn't mess up a configuration file. When I
upgraded
from 6.0 to 6.2, I found some stuff didn't make it over to
linux-2.2.14's area,
and I had to copy by hand.

Upgrading the kernel does not alter any system configuration files ,
only .config in /usr/src/linux. You upgraded your RH distro which is a
different situation.

Mandrake had added a RAID patch that has not been integrated into the
kernel tree yet. My RAID stopped working. I was using 'boot on raid' so
my error message was different.
It may be that you need to install this patch. It can be got from
http://people.redhat.com/mingo/raid-patches/
I'm not sure whether RH included this in the distro you are using.
