Hi,
It seems that you use a fresh 2.4.9 kernel. In kernel 2.4.9, the version
of LVM is 0.9.0-beta2, which is what you get with dmesg or cat /proc/lvm
Then you installed tools from 1.0.1rc2. You must upgrade your kernel
with LVM 1.0.1rc2 if you want all that to be consistent (or use beta2
tools, which is not the good way IMHO).
Recompile 2.4.9 with LVM-1.0.1rc2 and you'll be OK.
I applied the 1.0.1-rc2 patch to a clean 2.4.9 kernel tree and was
able to create a logical volume on top of s/w RAID 1 without any
trouble. However, a bonnie++ run on an ext2 (or ext3) filesystem on
the logical volume caused the system to lock up, with kswapd going
uninterruptible. I suspect a VM (rather than LVM) problem, as a
similar lock-up occurred on another system with 2.4.8 kernel and no
LVM. We've reverted to kernel 2.4.7 on both systems and had no
problems since.
