Change subject: core: handle Live Merge when top volume is larger than base ...................................................................... core: handle Live Merge when top volume is larger than base When a Live Merge is perfomed today, it internally performs a block commit operation to copy data from a volume to its parent. If the disk had been extended after the snapshot was created, the sizes of the two volumes will not match. In most cases the size is adjusted properly by the underlying processes performing the merge; to account for this, engine will update the size of the volume in the database to reflect the new, correct size. In the case of a raw volume on block storage, an explicit extension needs to take place before the merge. For this, a new child command of Live Merge has been added to run before the merge starts.
