The DCE Local File System (DCE LFS) is a high-performance, log-based file system. It supports the use of DCE LFS aggregates which are physically equivalent to standard UNIX disk partitions but also contain a specialized log of metadata about the structure and location of information they house.
DCE LFS aggregates, in turn, support the use of DCE LFS filesets. DCE LFS filesets are hierarchical groupings of files managed as a single unit. They can vary in size but are almost always smaller than a disk partition. As a result, multiple DCE LFS filesets can be stored on a single aggregate. Non-LFS filesets occupy the entire partition on which they reside.
Because of the differences between DCE LFS and non-LFS filesets, the following fts commands function only with DCE LFS filesets. Refer to the appropriate command reference pages for more information about the functionality provided by these commands.
