upgrade to rh7.3 broke lvm

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,

Yossi,

the upgrade should have brought you compatible user space and kernel LVM parts.

Can you find your VG(s) running vgdisplay?

/dev/mg0 is no valid logical volume name to be use for mounting. Must be something like /dev/YourVGName/YourLVName.
