[linux-lvm] LVM and 2.4.13

[linux-lvm] LVM and 2.4.13

[James Kelty]

Ok,

I created a new kernel using the latest patch from lvm 1.0.1-rc4.  I
compiled it into the kernel, and it loads pretty well.

I have a new 100GB drive that I carved into 4 slices w/ 8e as the type, did
the pvcreate w/o any problems,
created the vg00 volume group. But! When I try to create the logical volume,
I get a Seg Fault and core dump.

What's the deal?


--- Volume group ---
VG Name               vg00
VG Access             read/write

Does this work?

lvcreate -L73G vg00

James,

Take a look at Sistina's web page, and search Bugzilla for core dump.  There
is a documented issue with the version of GCC you are using, which is
happening because of broken compiler optimizations.  As I recall, there are
two workarounds.  First, you can edit your make file, and change -O2 to -O
or you can edit the source and add a printf() statement inside the function
which the compiler is to optimize by making it an inline function.

I chose the 2nd fix so I didn't have to get rid of all optimizations, but
that fix has to be applied in a number of places to make sure that all
command line tools get fixed appropriately.  The first fix has the benefit
of being changed in one place, and the entire works after recompilation, at
the cost of compiler optimization.

-- Mitch

P.S.  Seems like there is also another version of GCC which you can use, but
I don't know which one.

Thanks to everyone!  The optimization changes worked perfectly.

Try with the tools from lvm1rc1 or rc2. It corrected that for me. Kernel
can be in rc4 though.
