Creating and Using Filesets

Before you can create a DCE LFS fileset, you must first use the newaggr command to initialize, or format, the disk partition on which the aggregate is to reside; the newaggr command is comparable to the UNIX newfs command. You must then export the aggregate with the dfsexport command to make it available in the DCE namespace.

After the DCE LFS aggregate is initialized and exported, a DCE LFS fileset can be created on it with the fts create command. This command also registers the fileset in the Fileset Location Database (FLDB) and obtains a unique ID number for the fileset. To make the contents of a DCE LFS fileset visible in the DCE namespace, enter the fts crmount command to create a mount point for the fileset. After the fts crmount command is issued, the fileset is automatically attached to the DFS file system and is accessible to authorized DCE users.

On the other hand, when creating a non-LFS fileset, you do not use fts commands. Because a disk partition is equal to one non-LFS fileset, you use the newfs command (or the command appropriate to your operating system) to initialize the partition on which the non-LFS fileset is to reside. You then use your operating system's mount command (or its appropriate equivalent) to mount the partition locally, after which data can be placed on the partition and used locally. Note that if your vendor has properly modified your local operating system's mount command, you can also mount and use a DCE LFS fileset locally.

To make a non-LFS fileset visible in the DCE namespace, you first use the fts crfldbentry command to register the fileset in the FLDB and generate a unique ID number for it. You then export the partition on which the fileset resides with the dfsexport command and mount the fileset with the fts crmount command. The terms aggregate and non-LFS aggregate can also be used to refer to an exported partition.
