Do you really have 1.5 TB of text or is it 1.5 TB of postscript, pdf, or

Firstly, there's a discussion of some of the theoretical limits to the size
of a greenstone collection at
If you really do have 1.5 TB of text you will undoubtedly run up against one
or more of these limitations. The way to proceed may well be to split your
data up and create multiple collections from it.
Generally speaking greenstone isn't heavy on RAM so you could build a
collection as big as you like using your existing system (ignoring for the
moment the limitations mentioned above). It could take a long, long, time
though. If it took you 6 hours to build 100Mb of text you could make a rough
guess at 60 hours to build 1Gb or nearly 7 years to build 1 TB! You might
therefore consider getting the fastest machine you can lay your hands on and
building in linux instead of windows.
We've not previously built collections any bigger than a few Gb of text so
you're in unchartered territory here. All you can really do is try to build
it and see if it breaks. Let us know how you get on.
