Xsan Compatibility
Xsan 1.3 is not compatible with Compressor’s Apple Qmaster distributed processing
system when Xsan media drives are used for cluster (scratch) storage. To use Xsan with
Apple Qmaster 2.3, update to Xsan 1.4.
To download and install Xsan 1.4, go to:

Compressor Command-Line Usage Requires Login
While it is possible to use the command line to run an Apple Qmaster distributed
processing network, each Compressor service node (each computer providing
Compressor distributed processing services) must be logged in (with a Mac OS X
user name and password) for full functionality.
