							|  |  |  | 	  OCFS2 is a general purpose extent based shared disk cluster file | 
					
						
							|  |  |  | 	  system with many similarities to ext3. It supports 64 bit inode | 
					
						
							|  |  |  | 	  numbers, and has automatically extending metadata groups which may | 
					
						
							|  |  |  | 	  also make it attractive for non-clustered use. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	  You'll want to install the ocfs2-tools package in order to at least |
