mirror to thinpool conversion attempt passes when it should fail if it's not supported
Last modified: 2012-10-11 11:19:09 EDT
Description of problem: This is basically bug 858874, but with a mirror volume being converted instead of a linear volume. I'm not even sure if this is or is not supported, but bug 855171 appears to imply that it's not.
