Well, the CONFIG_SCSI_QLOGIC_ISP driver isn't supported, and you
may have noticed prints big warning messages when you boot with it.

Fortunately, the CONFIG_SCSI_QLOGIC_1280 driver has been extended
to handle the 1020 and 1040 devices.  I've been using that for a
while now on my ds10.

Re: Linux Alpha port: kernel panik under moderate DISK IO conditions

[Rao Davide]

I'm not using the qlogic controller as boot controller. I'm mooting from 
the internal disk connected to LSI controller.
In any case I'll try out the suggested 1280  right now.

Can I build a modular kernel with the 2.6 kernel series ?
I would find it handy to have som parts colpiled as modules.

Linux Alpha port: LVM

[Rao Davide]

Is LVM working on the alpha port 2.6 kernel series ?
If so where do I get libdevmapper so that I can build the userspace LVM 
utils ?

I tryied downloading 
ftp://sources.redhat.com/pub/dm/multipath-toolsmultipath-tools-0.4.3.tar.bz2
But I fail to compile it so I'm also unable tu build the userspace lvm 
utils.

Works for me.

Same place as you'd get it for any other system.  Doesn't your
distribution include it?

what do you think the 'dm' in that url stands for, hm?

'userspace lvm utils' can be found here:

ftp://sources.redhat.com/pub/lvm2

multipath tools might be something different ... :)

Are you using a redhat based distro (like suse, mandrake, alpha core or 
indeed redhat )?
Are you using stock kernel, libraries and tools or did you haveto build 
them yourself ?
Debian comes with LVM1 tools that do not work with 2.6 kernels so I need 
to compile them myself or install some ready build binary package for 
alpha processor and compatible with the libraries that come with debian3.
What alpha architecture are you running on ?

It may also have something more but it has libdevmapper in it ...
In any case I also tried downloading and compiling 
device-mapper.1.00.07.tgz from the link in the LVM2.
It builds and installe fine but I still get compilation errore when I 
build LVM2.
Configute is fine, here are a few lines concerning libdevmapper

checking libdevmapper.h usability... yes
checking libdevmapper.h presence... yes
checking for libdevmapper.h... yes

but when I try to compile:

I'm using kernel 2.6.11.7 downloaded from kernel.org.
Here's the relevent section for raid/lvm in config:

CONFIG_BLK_DEV_MD=y

Do I need to patch kernel ?

Re: Linux Alpha port: LVM

[Rao Davide]

Sorry to bother you all ... the problem was that I issued some options 
during configuration to specify where the kernel was, apparently I 
should only do that on 2.4 series kernels.

I re-extracted the kernel sources and started over again. It's nor 
working fine now.

Thanks anyway
