[linux-lvm] lvm 0.9 kernel build problems

[linux-lvm] lvm 0.9 kernel build problems

[Patrick Swartz]

Hello,

Could someone give me some hints to why I get the following error when
trying to build my kernel with the lvm 0.9patches.  This box started out as
a RH7.0 with all current RH updates, then installed the stock 2.4.0-test10
kernel with lvm built into the kernel.  This build worked.  I then applied
the two patches for 2.4.0-test10 and they applied cleanly.  I normally build
kernels using the following approach -- make dep clean bzImage modules
modules_install, then take care of lilo.  This error happens during the
bzImage stage.

Re: [linux-lvm] lvm 0.9 kernel build problems

I had the same errors in past when compiling it on 2.2.18pre kernels.
I believe my problem was that my /usr/src/linux didn't point back to the
proper kernel source tree.  It was a while ago though, but I'm thinking
that solved it for me.  I believe one of the files included in lvm.c is a
<linux/*whatever*> and that didn't exist or have the proper struct or
such.

RE: [linux-lvm] lvm 0.9 kernel build problems

[Patrick Swartz]

I have found a way around the problem I was having.  The first time I tried
to build the kernel I built lvm into the kernel, but I said "no" to the lvm
proc fs question.  This time I went ahead and said "yes" and everything
worked.
Now my question is having lvm report things to /proc will I notice any slow
downs?
Just courious.

Thanks for all of the hard work everyone is putting into lvm!!!!!!!

Patrick

RE: [linux-lvm] lvm 0.9 kernel build problems

[Jay Weber]

Ah thats' it.  Now my brain kicks in since you mentioned it.  That failure
from earlier only happens when you don't enable LVM proc-fs option.  I
guess it's a bug.  That's what I had todo.

Re: [linux-lvm] lvm 0.9 kernel build problems

[Heinz J. Mauelshagen]

I guess that this could be a nasty gcc flaw showing up here.

Anybody else who tried to patch/compile LVM 0.9 with linux-2.4.0-test10
on RH 7.0 who is able to help?

I think I already fixed that bug.
It will be available with 0.9.1

No.

Only if you read from LVM's /proc interface there's _very_ little load on
the driver.

Re: [linux-lvm] lvm 0.9 kernel build problems

[Heinz J. Mauelshagen]

Somebody figured that one out already.

It is a bug which shows up in case you deselect LVM proc filesystem support.

Please enable it for now and you should be able to compile quite happily.

tried, failed, gave up...

if anyone who knows more about what problems to expect wants
to take a shot at it i can put a copy of the 7.0 respin *
& 0.9 on a machine here and give you a login to try it out.

Let's package an old version of gcc just so we can compile the kernel
correctly.  We can't simply use a stable gcc as our standard compiler.
We have to reach back into the bag of the ancients to keep our
machines running and make it LOOK like we're using the bleeding edge

Good grief.  Is it just me, or has this thread been beaten to death
already on linux-kernel?

Connectiva, Red Hat, Debian and (I think) Mandrake are all shipping an
older compiler for the kernel now, simply because too many things in
the kernel are fragile and break if the compiler reorders instructions
in an unexpected way.

The fault here is actually the kernel's: if the kernel doesn't specify
its ordering constraints explicitly enough, then change the kernel and
you can break silent assumptions that the kernel was making, causing
obscure and hard-to-diagnose errors on SMP machines or when code is
interrupted.

This is nothing new --- since forever, there have been specific
compilers known to work with specific kernel versions, and using a
different compiler (older OR newer) has been likely to break things.

	If I'm not mistaken, the reasons the new gcc won't compile the
kernel have more to do with the kernel than with the new gcc.  This
problem has happened several times in the past, and it was usually (with
one notable exception in gcc 2.7.1) the kernel's fault.

Have fun (if at all possible),

I find it odd then, that I've had no problems compiling stock and
patched kernels with 3.95.2 that weren't my own fault.  Anyway, I'll
take this off list as its leaning toward being off topic and as it was
said earlier, this topic's been beaten to death on lkml.  Sorry for
bringing it up.
