lvcreate: illegal instruction

Переношу систему с одного харда на зеркало (SoftRAID + LVM).

# pvcreate /dev/md4
Physical volume "/dev/md4" successfully created

# vgcreate vgroup /dev/md4
Volume group "vgroup" successfully created

# vgscan
Reading all physical volumes. This may take a while...
Found volume group "vg" using metadata type lvm2
Found volume group "vgroup" using metadata type lvm2

# vgchange -a y
6 logical volume(s) in volume group "vg" now active
0 logical volume(s) in volume group "vgroup" now active

# lvcreate -L3G -nusr vgroup
Illegal instruction

Вроде как все делаю правильно, но создавать lv не хочет.
