Review Questions

  1. If you purchase a number of Xsan 2 licenses and want to enter them into Xsan Admin, what is the most efficient way to do so?
  2. When configuring the umask setting for a file or directory, you are concerned with read, write, and execute permissions. What is the maximum permissions value available in Mac OS X v10.5?
  3. You are considering the home folder situation for your brokerage firm and have determined that you need more user management options. In addition, your management wants to ensure that all user information is secured in a central location and cannot be lost should a laptop or other storage device be stolen or misplaced. What home folder solution would you choose for your organization and why?
  4. You have configured quotas on your SAN volume and set soft and hard quotas for specific groups. One of those groups has exceeded its soft quota past the grace period. What happens to the group’s data stored on the SAN?
  5. The vast majority of all command line tools you will see for Xsan begin with the letters CV. What does CV stand for?


  1. Place the serial numbers into a text file and drag the file to the Serial Number list in Xsan Admin.
  2. The maximum permissions value in Mac OS X v10.5 is 777. With a permissions level of 777 a user can read, write, and execute a file.
  3. Centralized management may lead you to network home folders. However, the fact that users have laptops and may want to work away from the office provides an opportunity to use mobile accounts. Still, data cannot be lost if a piece of equipment is lost or stolen, and mobile accounts cannot ensure this because they maintain a local copy of the user’s home folder. Therefore, network home folders are the only real solution.
  4. After the grace period has been exceeded, the soft quota becomes a hard quota and the group will no longer be able to save additional data to the volume until its members delete enough files to bring usage below the soft quota. The stored data remains on the SAN.
  5. The StorNext file system was originally named the CentraVision File System (CVFS). The CV stands for CentraVision.
