Rainer, Thank you for your interest in GlusterFS. I do not know of any user who's had an AFR configuration with 40-50 subvolumes, but there is no reason it shouldn't work. The write performance will obviously be quite low, but in your case since you will not be making heavy/daily use of it (the only writes will be when you make a new release, if I understand correctly), that shouldn't be an issue. The version of GlusterFS you're using (1.3.12) is rather old now. We have a new release 1.4.0 in the final stages of testing. We haven't yet completely tested the AFR-over-AFR setup yet. You could either wait a few days (less than a week) for us to make the RC1 release with AFR-over-AFR tested or grab the TLA repository version and give it a try.
