REORG FOR FILE SYSTEMS

ITEM: RTA000028779



Does the reorg command accomplish the same result as                            
backing up and restoring files to eliminate fragmentation?

A:  No, the "reorgvg" command works at the logical volume level and only        
    rearranges the physical partitions within a volume group to conform         
    to the placement policy for each logical volume, as best it can.            
                                                                                
    File system fragmentation affects the inodes and data blocks within         
    a file system.  This would not be changed by reorganizing the volume        
    group as the inodes and data are contained in logical partitions, and       
    only the position of the partitions are changed by "reorgvg".               
                                                                                
    More information on the "reorgvg" command and the general workings          
    of the LVM can be found InfoExplorer.  I highly recommend reading          
    "Logical Volume Storage Overview" article for information on LVM.
