Hello,

Is the Promise raid configured as a raid0 stripe? If so, can you see in the boot
messages if, when the ataraid driver detects the drives it is only detecting one
of the drives? Have you recently added or replaced one of the drives?

If the ataraid driver only detects one of the drives in a raid0 array, you might
try this patch:

--- /usr/src/temp/linux-2.4.21/drivers/ide/raid/pdcraid.c       2003-06-13

Hi,

Oh I forgot to say that i'm running RAID1 and it detects both drives
perfectly (I'm passing the IDE addresses to the kernel at boot time from the
lilo conf, see previous post). The system was reinstalled yesterday with two
brand new 80GB Western Digital disks (WD800JB-00DUA3). The thing is, I have
succesfully installed the TX2000 card with the native ATARAID drivers before
using two 30GB Maxtor (something) disks and kernel 2.4-20 - 2.4.23. I wonder
why I can't get it up and running now. It will only work with the pre
compiled kernel shipped with Debian 3.0 (2.4.18-bf2.4). I have tried all
sorts of kernel settings. Since I have got it to work before I think should
be able to do it again.

Please advise.

Hmmm. I'm pretty sure that the partitions are enumerated the same way in 2.4.23
vs. 2.4.18.  There was a change in the way IDE geometry was returned from the
kernel that caused a hiccup in the pdcraid driver around 2.4.22 I think?  My
patch just tells the pdcraid to use an alternate method of finding the RAID
superblock on each drive. Not sure what else might be the problem. Do you see
the ataraid driver fire up (looking something like this):

ataraid/d0: ataraid/d0p1
Drive 0 is 239372 Mb (33 / 0)
Drive 1 is 239372 Mb (34 / 0)
Raid1 array consists of 2 drives.
Promise Fasttrak(tm) Softwareraid driver for linux version 0.03beta

The only problem I've recently come upon with pdcraid, is when it detects just
one of the drives and fails. I didn't think that should happen with raid1 though.

RE: Error mounting root fs on 72:01 using Promise FastTrak TX2000 (PDC20271)

[Nicklas Bondesson]

Nopes, I get the kernel panic before the driver loads or when it does,
however I'm not seeing any ataraid driver message at all. This is really
strange I think. The only thing that has changed in my setup are the
harddrives. I really need to get this working. Do you have any suggestions
what-so-ever what to do? I really appreciate your help on this.

Well, since you're using raid1, you should be able to pass a root=/dev/hda1 (or
whatever your / is located) using the same kernel and at least boot using this
kernel. Then maybe you can use dmesg etc.. to see what the driver is actually
doing. From your original post, it looks like you're using Lilo, so you'll need
to boot using the old kernel first and change the lilo entry.

RE: Error mounting root fs on 72:01 using Promise FastTrak TX2000 (PDC20271)

I will try to do that now. Do you think this can have anything to do with me
actually having a rather large root partition (76GB)? I will try with two
33GB partitions this time (it might have something to do with it - but on
the other hand it is working working with the Debian pre-compiled kernel).

Well, let's see what I find out. I'll keep you posted.

RE: Error mounting root fs on 72:01 using Promise FastTrak TX2000 (PDC20271)

[Nicklas Bondesson]

Now I'm sucessfully booting my system with the 2.4.23 kernel using only one
of the drives (hde). There is not a single line in the logs that says
anything about the Promise ATARAID driver is beeing fired up, so my guess is
that it doesn't load if no one is calling on it. When I try to boot from the
RAID it dies right after the "NET4: Unix domain sockets 1.0/SMP for Linux"
message. I think it's when the ATARAID driver is about to fire up. I have no
idea at all what to do now. It must have something to do with the hard
drives since this is the only thing that has changed. Maybee I'm missing
some important kernel setting option or so? (I don't think so, but one never
know for sure). Also what have changed in the Promise / ATARAID since
2.4.18?.

Not sure what else to tell you. If the pdcraid driver is compiled into the
kernel, you'll get a message about it during boot, even if it can't find all the
drives. I no longer use the 2.4 kernel series (or pdcraid), so I'm afraid I'm
out of ideas. Maybe somebody else on the list has some other things to try. Sorry.

I believe that should do it. dmesg doesn't have any info about the ataraid
driver being loaded? If it's scrolling out of the kernel buffer, you can try
bumping up the size through the kernel config. The option is under the "Kernel
Hacking" section and is CONFIG_LOG_BUF_SHIFT. Change it to 17 or 18 to be sure.
A reboot with this new kernel should give you a full dmesg afterward, hopefully
showing what's wrong with the ataraid stuff.

-Walt

PS. I don't remember when this took place, but there were some changes to the
promise drivers in 2.4 around 2.4.21 I think. There should be drivers for both
the older Promise and the newer. I remember always choosing both, complete with
pdcraid just to be sure.

RE: Error mounting root fs on 72:01 using Promise FastTrak TX2000 (PDC20271)

[Nicklas Bondesson]

No problem I can see the whole boot log. The ATARAID driver never loads.
Could you force it to load somehow?

I get these messages:

PDC20271: IDE controller at PCI slot 00:09.0
PCI: Found IRQ 12 for device 00.09.0
PCI: Sharing IRQ 12 with 00:04.2

PDC20271: not 100% native mode: will probe irqs later
	ide2: BM-DMA at ...
	ide3: BM-DMA at ...

then it finds the disks:

hdg: WDC ...

hdg: hdg1, hdg2

I just downloaded and compiled the 2.4.18 kernel and it works perfectly. It
must have something to with any changes from 2.4.18 - 2.4.23. I will try
which version up until 2.4.23 that works. I'll keep you posted. Do you know

Well, not really sure. I thought Alan Cox did the original pdcraid.c for linux
some time back, but it really hasn't seen many changes. There were two general
Linux changes that took place back around 2.4.22 that might affect you. The
first, was the addition of the new Promise IDE driver, which you've got
configured. The second,  has to do with how Linux reports the geometry of a
drive. This change affected my setup which is why I wrote the patch for the
pdcraid driver. If your system makes it all the way through kernel booting
(which it seems to do), but can't mount the filesystem on the raid, it seems to
indicate the latter change affecting you also. The only other thing I can think
of, is to use my patch (attached) with patch -p1 < pdcraid.patch from your
/usr/src/linux and make sure that you've got both Promise drivers compiled in
your kernel. Recompile and see what happens. Outside of that, I'm stuck. Good luck,

The patch did not work for me, in fact there was no change at all (anything
affected to me). The Promise ataraid driver never gets loaded.

Not sure what else to try. I see that you've already posted to the ata-raid
list, so I'd hope that somebody else would reply from there. The pdcraid driver
has not received much attention lately, so it may very well be broken for your
configuration. Promise has released a binary/source combo driver similar to
Nvidia's that will still work in 2.4 - you might give that a try. I have a
PDC20276 based onboard raid setup, however, I use 2.6 with device mapper to use
it. It's a bit of a pain to setup ATM - especially if you want to boot from it,
but it can be done. Good luck,

RE: Error mounting root fs on 72:01 using Promise FastTrak TX2000 (PDC20271)

Finally got it to work!

There must be a bug causing the Promise card / driver not to be fired up
(i'm using ab ASUS P2B motheroard). If I issue the "acpi=off" to the kernel
at boot it detects the card and fires up the driver. Everything seems to
work now. Who should I post this bug to so it can be fixed in coming
releases?

The fix for me was to disable all "Power Management" in the kernel and
re-compile it. Works like a charm now :)

Hope this can help anyone else with the same problem as me. But again, I
think someone should take a look at it cos I think this is a bug for sure.

Nicke,

Glad to hear you got it working. Check out http://acpi.sourceforge.net for acpi
related information. If you can get it working with acpi=off and it doesn't when
you don't pass that flag, I'd say that there's at least something fishy
happening with acpi on your machine.

As for getting it running on 2.6 with dm, the only way I know of is to create a
custom initrd file by hand. You have to compile the lvm-dm tools statically and
create mappings first. Then in the linuxrc script, you need run dmsetup and
point it at the config files to create the devices. Until this is handled better
it's not really recommended. Good luck,

-Walt

RE: Error mounting root fs on 72:01 using Promise FastTrak TX2000 (PDC20271)

[Nicklas Bondesson]

Thanks for the info, but yet I had to go with your patch to get it up and
running. I think the patch should be included in the official kernel
release.

Who should we send this to?

Hi Nicke,

It's been included in messages to ata-raid, however, I never sent it there
marked as PATCH. I suppose I should wrap it up, describe it and sent it off the
the ata-raid list for completeness. Maybe it'll save somebody else from the
process you just went through :)

I just realised that I need to have the kernel patched with Walt's pdcraid
patch in order to get it to work. Conclusion: disable all Power Management
options and patch the kernel with Walt's pdcraid patch (attached). That will
do it. I think that Walt's patch should be included in the official kernel.

Nicklas,

Have you tried to compile the kernel with CONFIG_PDC202XX_FORCE unset ?

RE: Error mounting root fs on 72:01 using Promise FastTrak TX2000 (PDC20271)

[Nicklas Bondesson]

Yes, if I remember it correctly I have tried that too. Should it make any
difference? It seems like the problem is related to disk geometry failure
(the kernel is not seeing the correct geometry values for the drives) since
the patch I got worked fine.

Error mounting root fs on 72:01 using Promise FastTrak TX2000 (PDC20271)

[Nicklas Bondesson]

I have some major problem getting my FastTrak TX2000 card working with the
Linux 2.4.23 kernel using Debian 3.0 r2.
 
Everything seems to work just fne with the precompiled kernel shipped with
Debian (2.4.18-bf2.4) but when I try to use the newer kernel the boot
process halts and give me a kernel panic:
 
Kernel panic: VFS: Unable to mount root fs on 72:01.
 
I'm using the native ATARAID driver built in (not as a module).
 
I have sucessfully used the RAID card with two Maxtor drives for almost a
year (even with the 2.4.23 kernel). But I reinstalled the system yesterday
with brand new disks.
 
I think I have tried almost every way possible getting the board up, but no
luck! Have I missed something here?
 
I hope that someone can help me with this issue. Thanks in advance!
