The DCE Distributed File Service (DFS) is a distributed client/server application that presents the DCE with a global view of a set of files and directories (a file system), independent of machine boundaries.
Each user has associated with there account a set of files. The files are stored in a fileset within DFS. Each account with have a separate fileset with the fileset having the same name as the account. Each fileset has a quota associated with it. The quota is the sum of all space used in the fileset.
The main mount point for all filesets is /.:/fs or /:. Under the main fileset mount point will be a series of directories in the form of cnn where nn will be a two digit number from 00 to 99. Under each of the cnn directories will be a series of directories in the form of dnn where nn will again be a two digit number from 00 to 99. Users fileset will be stored under the dnn directories depending on the last four digits of the accounts UID. If a account has a UID of 16278 then the home directory for the account will be /:/c62/d78/username. The purpose of the cnn and dnn directories is to break up the number of users directories in a single directory tree.
Each Web user will have at least one fileset mounted under their DFS home directory for web access. The fileset names will be username.public_html or username.private_html. The public_html fileset will be used by the httpd server on weber as the place for users home pages. The private_html fileset will be used by the httpd server on neruda as the place for users private pages. The users will get access to the private or public dfs fileset via a symbolic link in their home directory called public_html or private_html.
Neruda is in the process of being setup to run as a DFS fileserver for restricted web pages. Neruda will act as a test to see if DFS can be used for web pages that are currently on weber. The users of neruda will have a link in their home directory (called private_html) that will point to the users dfs home directory (see section above on user directories). This directory will be mounted on neruda and web users will gain access to the directory the same way that weber uses.
