[linux-lvm] Segmentation Fault with vgextend and LVM 1.0.1rc4

[Jean-Noel GADREAU <cathjn@gadreau.net>]

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.
Regards,
