The disk you're trying to use with EVMS is already mounted.  Therefore
the device mapper doesn't allow EVMS to "takeover" the disk.

To resolve the problem you can either apply the bd-claim patch or turn
your root filesystem and swap space to EVMS or compatibility volumes and
mount those instead.

See the passage about "Volume Activation" in the EVMS FAQ at
http://evms.sourceforge.net/faq.html for details.
