This command was only successful in LVM 2.02.178-rc1, but failed in 2.02.177.

I created a report in bugzilla [4], but since the `cache_cmeta` LV appears to 
contain parts of my personal files, I cannot attach it.  However, I gained 
access to the metadata LV now and would be able to provide you access to 
certain specific parts of it, if requested.

My goal is still to gain access to as much of the data as possible.
