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.
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
Thanks in advance for answers, and for your great job.
