***@testbox:~$ sudo lvcreate -L16G MyVG -n Metadata
Logical volume "Metadata" created

But when I attempt the conversion, I do not get what I would expect:

***@testbox:~$ sudo lvconvert --thinpool MyVG/OldThickLV1
--poolmetadata MyVG/Metadata
Converted MyVG/OldThickLV1 to thin pool.

Then the OldThickLV1 disappears, leaving Metadata around:

***@testbox:~$ sudo lvdisplay

Am I doing something wrong here?
Or am I going to have to create a new thin pool, new thin logical
volumes, and copy the data over?


Thanks,
