No, not true. (At least not today) Ext2/3 has advanced algorithms to make sure that the blocks that are allocated avoid fragmentation, but it is not doing any kind of dynamic moving of blocks/inodes. (At least, not yet; there has been some talk about creating enough kernel hooks so that a user-space program could do dynamic defragmentation of the filesystem, but none of this exists at the moment.) - Ted _______________________________________________ Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
