https://bugzilla.redhat.com/show_bug.cgi?id=1318993 Commit id 'dd519a294' caused a regression cloning a volume into a logical pool by removing just the 'allocation' adjustment during storageVolCreateXMLFrom. Combined with the change to not require the new volume input XML to have a capacity listed (commit id 'e3f1d2a8') left the possibility that a zero allocation value (e.g., not provided) would create a thin/sparse logical volume. When a thin lv becomes fully populated, then LVM sets the partition 'inactive' and the subsequent fdatasync() fails. Add a new 'has_allocation' flag to be set at XML parse time to indicate that allocation was provided. This is done so that if it's not provided the create-from code uses the capacity value since we document that if omitted, the volume will be fully allocated at time of creation. For a logical backend, that creation time is 'createVol', while for a file backend, creation doesn't set the size, but the 'createRaw' called during buildVolFrom will decide whether the file is sparse or not based on the provided capacity and allocation value. For volume clones that provide different allocation and capacity values to allow for sparse files, there is no change.
