Suggested file system structures for user directories and files

z/OS UNIX System Services Planning
GA32-0884-00

For users, you should logically mount other file systems on the root file system. Have your users place their directories and files in the mounted file systems. Separate user file systems offer several advantages:
  • Managing storage is more efficient because the system administrator only needs to allocate data sets that are large enough to accommodate the needs of individual users.
  • Isolating failures is easier because the system administrator can unmount the user file system that caused an error without affecting other users' data or causing z/OS UNIX to fail.
  • They relieve the contention for system resources that might occur by having multiple users in a single file system.
Rules: When working with file system structures, follow these rules:
  • Name each user's home directory /u/userid where userid is the user ID in lowercase.
  • Keep system file systems separate from user file systems by putting the file systems on different volumes.

Tip: For easier management of file systems, use the automount facility. It is described in Using the automount facility.
