A DCE LFS fileset is a hierarchical grouping of files that is managed as a single unit. A DCE LFS aggregate is a disk partition that is modified to include the DCE LFS metadata structure that supports DCE Access Control Lists (ACLs), multiple DCE LFS filesets, logging, and other fileset-related operations.
Using DFS, you can share information stored on the local disks of different machines by exporting aggregates and partitions from the machines. Exporting an aggregate or partition makes the filesets contained on it available in the DCE namespace. With the DCE LFS, you can export multiple filesets from one aggregate. Because non-LFS partitions do not support the enhancements that are supported on DCE LFS aggregates, and because you can store only one fileset on a non-LFS partition, you can export only one non-LFS fileset per non-LFS partition.
The figure below illustrates the structural differences between the DCE LFS and other file systems. The partitioning structure in the DCE LFS features aggregates, each of which can store multiple DCE LFS filesets; the partitioning structure in other file systems has partitions that can house only a single non-LFS file system each. (Note that the disks in both structures include a non-LFS boot partition.)
