        Disk /dev/md0: 300GB
        Sector size (logical/physical): 512B/512B
        Partition Table: loop
        
        Number  Start   End    Size   File system  Flags
         1      0.00kB  300GB  300GB  ext3              
        
        Information: Don't forget to update /etc/fstab, if necessary.
