Description Jonathan Earl Brassow 2014-11-12 23:40:22 UTC
Add detection of SSD and give warning if rotational drive is used for metadata.  If we don't have this then the user should be forced to specify the metadata dev (either explicitly or via a tag).

This request requires LVM to be able to detect the type of PV it is dealing with.
