Hi Julian,

It is not clear what are you trying to do - is this lv on shared storage, and 
accessed
by multiple hosts or use only one host?

If the lv is shared, you cannot create a file system and mount it on multiple 
hosts (unless you
are using cluster file system).

If this local storage for one host, you should create a file system and mount 
it, and then
you can use the mountpoint as local storage.

Please describe in details what are you trying to do and how did you create the 
storage
domain in the engine side.
