You do not seem to understand my message.  YOU must create this file, no 
one else connected to NRAO or AIPS will do it.  This file points at one 
or more data areas that YOU create.  Note that after you create the data 
areas and list them in the $HOME/.dadevs.always file, you must also 
create a zero-byte file named SPACE with at least owner and group write 
privilege.

As an example only (DO NOT COPY the directory names):

    cd
    cd   /lustre/cfa/users/wfong
    mkdir AIPS
    cd AIPS
    mkdir LUSTRE_1
    mkdir LUSTRE_2
    touch LUSTRE_1/SPACE LUSTRE_2/SPACE

Then edit the file $HOME/.dadevs.always to look like

+  /lustre/cfa/users/wfong/AIPS/LUSTRE_1
-  /lustre/cfa/users/wfong/AIPS/LUSTRE_2

Remember that these directory names probably cannot be used in your set up.
