Hello we consider using glusterfs in "production" for our small computation cluster. I've been reading docs and following mailing list for a while, but i still have some questions: Aim is 20 nodes (x4 cores) with 1TB disk each, on gigabit switch - we are interested in AFR + unify for having 10TB x2 replications - maybe NUFA - we have tons of small files (10kB) which are our read bottleneck - we want performance (currently we easyly exhaust 4 NFS servers) - our users won't do concurrent write to the same file, except append to logfile (we don't care of order as far as everything is logged) 1/ which version should we use? 1.3.9.tgz or some more recent from tla ? 2/ i guess we should use all the performance modules 3/ docs seems to say we should do (unify over NUFA over AFR) ? or is it better to keep it simple and do only (unify over AFR) ? 4/ i'm a bit confused about namespaces, especially if we use unify + NUFA + AFR. I probably missed a link explaining ns and how avoid single point of failure. Btw, http://www.gluster.org/docs/index.php/GlusterFS_Volume_Specification should be better advertised in documentation, as it is so important. I'll write my step-by-step-glusterfs-howto-for-newbies and send it if we succeed. Thanks in advance for answers, and for your great job. Best Regards. Alain Baeckeroot
