Hi.

I have a problem to extend my current volume group "vg01". I did:

# pvcreate /dev/hde1 /dev/hde2
pvcreate -- physical volume "/dev/hde1" successfully created
pvcreate -- physical volume "/dev/hde2" successfully created
# vgextend -v vg01 /dev/hde1
vgextend -- locking logical volume manager
vgextend -- checking volume group name "vg01"
vgextend -- checking volume group "vg01" existence
vgextend -- checking for inactivity of volume group
vgextend -- reading data of volume group "vg01" from lvmtab
vgextend -- INFO: maximum logical volume size is 255.99 Gigabyte
vgextend -- reading data for all physical volumes from disk(s)
vgextend -- extending VGDA structures of volume group "vg01"
vgextend -- volume group "vg01" will be extended by 1 new physical volumes
vgextend -- extending volume group "vg01" by physical volume "/dev/hde1" in kernel
Segmentation fault (core dumped)

I am using RedHat 7.1 with a custom kernel to have LVM (2.4.9-6). I have 2 drives on this IDE controller (a Promise UltraDMA100DX2) and both work fine with linux. My secondary drive (/dev/hdf is already part of vg01).

I don't know if this is a bug or if I am not using this correctly. I could not find anything on the internet about this particular problem.

For more information, I am including the results of several commands. Let me know if you need more information.

Thanks in advance for your help.

Jean-Noel GADREAU

vgextend -- extending volume group "vg01" by physical volume "/dev/hde1" in kernel
Segmentation fault (core dumped)

I am using RedHat 7.1 with a custom kernel to have LVM (2.4.9-6). I have 2 drives on this IDE controller (a Promise UltraDMA100DX2) and both work fine with linux. My secondary drive (/dev/hdf is already part of vg01).

[snip]

The stock linux kernel comes with an old version of lvm. Please grab the latest version and make sure to patch your kernel (see PATCHES/README in the lvm distribution). You should also upgrade your userspace tools (lvcreate, vgextend and the like).

On a further note, check which compiler you are using. gcc-2.96 should be used without optimization (-O0) and make sure you do not use gcc-3.0.x (it produces broken code on some occasions, this happened to me with the lvm tools).

good luck,

Nils

Thanks for your quick reply. I rebuilt the kernel but it did not work. However, recompiling without -O2 did it for me.

What I did (for those who might run into the same problem):

#cd LVM/1.0.1rc4
#./configure

Quoted 1 line
Quoted 1 line
Quoted 1 line

here, edit make.tmpl to change CFLAGS=.... -O2 .... to CFLAGS=... -O0 ... <<<

#make
#make install

Thanks again for your time and quick answer.

Jean-Noel

Hello Jean-Noel,

I had similar problem so I cvs'ed latest lvm code and installed it.

It works much smoother for me now...

Hope that help.
