Which part of your pipeline is giving you the errors that you want trapped?

The way you have the pipeline written only gzip errors will be sent to the log file. If you want all errors, from any process in the pipe, written to the log try this:

Code:
(find /home/testuser -depth | cpio -oavc | gzip >/media/backup_drive/test.cpio.gz) 2>/media/backup_drive/errout.log

The pipeline is run in a sub-shell and the stderror from the subshell (all processes) will be sent to the log file.

If the errors you are trying to trap are just from gzip, then I'm not sure what is going on as your code looks ok from the brief scan I did.

GLBINDPROGRAMPIPELIN(3G)					  [FIXME: manual]					  GLBINDPROGRAMPIPELIN(3G)

NAME

       glBindProgramPipeline - bind a program pipeline to the current context

C SPECIFICATION

       void glBindProgramPipeline(GLuint pipeline);

PARAMETERS

       pipeline
	   Specifies the name of the pipeline object to bind to the context.

DESCRIPTION

       glBindProgramPipeline binds a program pipeline object to the current context.  pipeline must be a name previously returned from a call to
       glGenProgramPipelines(). If no program pipeline exists with name pipeline then a new pipeline object is created with that name and
       initialized to the default state vector.

       When a program pipeline object is bound using glBindProgramPipeline, any previous binding is broken and is replaced with a binding to the
       specified pipeline object. If pipeline is zero, the previous binding is broken and is not replaced, leaving no pipeline object bound. If no
       current program object has been established by glUseProgram(), the program objects used for each stage and for uniform updates are taken
       from the bound program pipeline object, if any. If there is a current program object established by glUseProgram(), the bound program
       pipeline object has no effect on rendering or uniform updates. When a bound program pipeline object is used for rendering, individual
       shader executables are taken from its program objects.

ERRORS

       GL_INVALID_OPERATION is generated if pipeline is not zero or a name previously returned from a call to glGenProgramPipelines() or if such a
       name has been deleted by a call to glDeleteProgramPipelines().
