To be clear, you tested *snapshot* creation, not jjust LV creation, yes?

Was originally @ report

    rpm -qa | grep -i lvm2
        lvm2-2.02.120-62.1.x86_64

Now currently is

    rpm -qa | grep -i lvm2
        lvm2-2.02.120-64.1.x86_64

Also

    rpm -qa|grep udev
        udev-210-86.1.x86_64
        libgudev-1_0-0-210-86.1.x86_64
        libudev1-210-86.1.x86_64
