aoetools 3

Hi!

Is aoetools3 support 2.4.x kernels? Or maybe a better question when will
aoetools support 2.4.x? I don't like 2.6 it is not as stable as 2.4.

aoe in 2.6.11.7

Hi!

I'm trying to compille 2.6.11.7 and I found in the blockdevices:
ATA over Ethernet support:

----
This driver provides Support for ATA over Ethernet block devices like
the Coraid EtherDrive (R) Storage Blade.

There are some parts of the aoetools that don't really have to do with
the Linux kernel driver for AoE.  The aoeping program, for example, is
a purely userland utility.  It should work on a 2.4 system, although I
haven't tried it yet.

> Or maybe a better question when will aoetools support 2.4.x? 

There are no plans to make the kernel-dependent parts compatible with
the 2.4 driver.  There are a few reasons ...

  * The 2.6 driver is in the Linux kernel proper, so there's a need
    for supporting software distributed in a separate package.  The
    2.4 driver is only available as a third-party driver outside of
    the 2.4 kernel itself.  That third-party distribution is self
    contained.

    That is, the kernel-related parts of aoetools aren't needed by 2.4
    users, and the non-kernel-related parts are already usable by 2.4
    users.

  * Distros will be moving away from 2.4 as new ones continue to use
    2.6 and old ones wane in popularity.  It keeps the aoetools simple

Yes, the aoe driver became part of the mainline kernel just before
2.6.11 came out.  Now that it's in there, aoe support will be a part
of many distributions.

That means now's the time for the aoetools to be released as
distro-specific packages, an rpm for Fedora Core, a deb for debian,
etc.

removeing an aoe device

Hi!

How can I remove a aoe device? (shown in aoe-stat)

I stopped vblade on the sharing pc, and aoe is still show me in
aoe-stat.

e0.0 eth1 up
e0.1 eth1 up
e1.0 eth1 up

thanks

Compiling aoe

Forgive my newbie questions.

So, I have two options for AoE support, right?
Compile the aoe module, or use a very recent kernel with AoE built in.

When I attempt to use the aoe module I complied I get a invalid
module format error, which I understand is because my kernel
and the module don't match.  Since I'm using a 'canned' precompiled
Debian kernel 2.6.8-2-686, I not really sure how it was compiled.
Specifying a machine type of 686 while compiling aoe didn't do it.

So what easiest?

1)Somehow find out the correct compile options that I need to compile
aoe with my current kernel,
2)Recompile my current kernel with known options (which may not be
obvious to me since the actual compiler options are buried behind
the configuration tools),
3) pull a precompiled 2.6.11 kernel out of debian unstable.

The last option all well and good for testing on my Debian desktop,
where system reliability doesn't matter very much.  Upgrading the
kernel on my Suse based Novell OES server really isn't an option, but
I have the same issue there.

Thanks for any advice.

Yes, that's right.  There's the standalone driver and the in-kernel
driver.

You're on the right track.  You just have to make sure that the kernel
sources that are used during the build of the standalone aoe module
match the kernel that you're running.

There should be debian documentation for your kernel sources (the ones
for the 2.6.8-2-686 kernel you're running), with information on how to
compile third-party drivers.  A debian forum would be a good place to
ask about this if you have trouble.

I think the better way to compille your own kernel. I successfully
compilled aoe with 2.4.x and 2.6 series too.
It is awalys a good idea to compille your own kernel, only use the
drivers what matches your hardware.

Right now the aoe-stat output just reflects the driver's idea of what
devices are out there.  Unless someone in userland tries to use the
device, the driver has no idea that it has gone away.  If someone does
try to use the device, the driver will change its state to "down".

So you can't really tell the aoe driver, "Forget about device eX.Y,"
at this point.  Of course, you can unload and reload the driver if
it's a module, and that will give you a clean slate.

I don't know if it matters.  I guess it might be desirable to be able
to tell the driver to forget about absent devices and so to make
aoe-stat's output more accurate and succinct.

raid again

Hi!

I started to play again with aoe (vblade5) now with kernel 2.6.11-7.
The accessing speed increased!

But I can't create an md device, if I use a new mdadm (1.8, 1.9):

mdadm --create /dev/md3 --level=1
--raid-devices=2 /dev/etherd/e0.2 /home/hygy/cluster/image1.fs

If I use:
losetup /dev/loop0 /home/hygy/cluster/image2.fs
than it creates the array.

Can I use the mdadm with only a loop device with aoe, or a regular file?

thanks
HyGy
