Archived - About the Xsan 1.4.1 update

This article has been archived and is no longer updated by Apple.

There are two updates for Xsan 1.4.1: "Xsan 1.4.1 Update for 10.4" and "Xsan Admin 1.4.1 Update". These are available from both Apple Downloads and Software Update.

Important: Read before continuing

Before installation

  • Xsan 1.1 or later is required in order to install Xsan 1.4.1.
  • If you are setting up a new Xsan deployment, please see this article for the proper installation order.
  • Be sure that all Metadata Controllers (MDCs) are updated before you make any configuration changes.
  • Before installing, please review the Xsan Migration Guide.
  • During installation, do not change any Xsan settings using Xsan Admin or a command-line tool.

After Installation

To prevent an inconsistent volume state, run the cvfsck command on each Xsan volume after the MDCs have been updated with Xsan 1.4.1 Update.

Metadata Controller (MDC) software version

Your MDCs must always have software versions (both Xsan and Mac OS) that are the same or more recent than the most recent client versions. Specifically, if any client in your Xsan network is using Xsan 1.4.1 with Mac OS X 10.4.8 or later, then your metadata controllers (MDCs) must also be updated to Xsan 1.4.1 on the same version of Mac OS X.

Software Update Installation

Software Update may have referred you to this document. Because some updates are prerequisites for others, you may need to use Software Update more than once to get all available updates.

Standalone Installer

A standalone installer is available from Apple Downloads.

Remote Installation

If you need to install the update on a remote computer, use the softwareupdate command-line tool.

Hardware Requirements

  • Xserve or Xserve G5
  • Mac Pro
  • Power Mac G5 (any)

Storage Network Requirements
