[linux-lvm] upgrade to rh7.3 broke lvm

[Yossi <yossi Mooncrest Net>]

Upgraded from RH7.1 to RH7.3. The 7.1 was built with the lvm patch to
the kernel. The 7.3 RH kernel has lvm built in. After the upgrade, I
receive the message "/dev/mg0 not a block device" when I try to mount
it. I tried exporting the vg and importing it without errors but it
still doesn't mount. I suspect that this may be due to different
versions of the kernel part of the lvm versus the usermode parts of lvm.

Thanks for any help,
