text: **7.1.5 Striped and sequential volumes**
  
  The*type*attribute of a volume defines the method of allocation of extents that make up the 
  volume copy: 
  
  (cid:2) A*striped*volume contains a volume copy that has extents that are allocated from multiple 
  MDisks from the storage pool. By default, extents are allocated by using round-robin 
  algorithm from all MDisks in the storage pool. However, it is possible to supply a list of 
  MDisks to use for volume creation. 
  
  **Attention:**By default, striped volume copies are striped across all MDisks in the 
  storage pool. If some of the MDisks are smaller than others, the extents on the smaller 
  MDisks are used up before the larger MDisks run out of extents. Manually specifying 
  the stripe set in this case might result in the volume copy not being created. 
  
  If you are unsure if sufficient free space is available to create a striped volume copy, 
  select one of the following options: 
  
  (cid:2) Check the free space on each MDisk in the storage pool by using the**lsfreeextents**
  command. 
  
  (cid:2) Allow the system to automatically create the volume copy by not supplying a specific 
  stripe set.
