Hi there guys..

I'm getting nuts trying to make this work....

the dmraidinitrd script fails.... the "genkernel --udev --dmraid" also fails....

dmraidinitrd script:

Yeah, think I got that error at some stage too. Check your initrd support in the kernel.

It is possible to log it to a file (floppy disk usually - since you can't see your hard disk yet). I've never done it, and I don't know how it is done, but when you get given a shell (after the boot fails) try:

Phk, I think you are using Devfs causing the problems with the /dev/mapper/control device. Why don't you use udev?

Well, i think i'm using udev!!

I'll show you what i've done:

Guess we'd better continue my issue there, to don't fill up this how-to....

Thanks.

(I've edited the post, and i've managed to copy my output errors to a floppy. I'll post my config files, and outputs, there.)

(And yes, there seems to be a problem with DEVFS and\or my SATA drivers...)

In first post Irondog suggested this:

Nope, i've done it too! However, i've built the initrd with the script "dmraidinit" (in the gen2dmraid homepage)

But if you want, i can go and check those package's versions!!
Do you think i should?

My kernel settings were wrong... DevFS was checked, and I was blind.... :oops:

So know the system boots... for more 3 or 4 seconds until a file-system check error, and then only the maintainance console is available...

Well, i've changed the "/etc/init.d/checkfs" script, so that it wont break if a filesystem-check-error occurs...
I know this is a bad policy, but it's only temporary

I won't keep doing the installation until i've fixed this.

Now, all the above problem have disappeared, except for this one:

Nope, the error was even more stupid than the DEVfs one.....

I just followed this howto for installing on my sil1332 sata raid.
I was able to get through the install fine, but when I reboot, I get a grub prompt.
I booted with the CD again and reran all of the grub related parts, and I still get the same thing.
I know very little about grub. Is there a way to have it spit out information that might tell me why it isn't booting?

Thanks.

7 messages above. Sounds like grub can not find grub.conf, but if you use a grub floppy to setup grub you will see the devices as grub truly sees them and can verify your

root line in grub.conf

I have followed the HOWTO but with booting i get some problems

I had an idea of why grub might not be finding my devices.
If I use udev instead of devfs, do I need to use different device names than /dev/mapper/sil_blahblah1 in grub and fstab?
Will booting with a grub floppy show me those new names?

kabage · Guru Joined: 31 Jan 2005 Posts: 340

Grub floppy will show devices as (hdX,X) no matter what kind of devices.
But ntldr and grub may not look at them the same so, if you boot ntldr at (hd0) which then chains to grub at (hd0,x) [which ever boot partition you use] then grub may suddenly be seeing
(hd1,x) or course if your referring to the root device in grub.conf like so

I've got the following in grub.conf.

For your boot , and I'm not sure why devmapper maps device partitions with such names.

I changed my grub to point real_root to sil*4.
I rebooted and grub complained that I had a bad partition table.

I booted with the CD again and did a grub setup (hd0) to install to the MBR.
Now when I boot, I get a grub error 18.
My partitions are:
sil*1 /boot 30MB
sil*2 winxp 110GB
sil*3 swap 2GB
sil*4 / 180GB
So I don't see why I'm getting the error 18.

is there any livecd for amd64 with dmraid? the official doesn't seem to work... while the x86 do work, and gen2dmraid also... so would it be a amd64 version of gen2dmraid?
