Why not start with my cycsetup perl program, which takes some info
about the layout of each metacycbuff, number and sizes, directories, and
generates the cycbuff file and a shell script which does the init. It
even has an option to initialize cycbuffs in different directories in
parallel, which assumes that they are on separate drives. This will
bring a TB EMC box to its knees!
If any interest I'll put it up in a semi-public place, maybe it should
be in the contrib as well.
