Hi Krishna, I'll clarify a bit by saying the main purpose of having cluster/unify plus AFR is to have an expandable grid file system but have redundancy on it too. I don't mind having to restart the daemons or remount the glusterfs volume. I have the funds to build a 20 node glusterfs cluster and I was thinking that 20 machines each with 2x750Gig SATA drives in cluster/ unify would yield around 25-30 or so TB of storage. An EMC san of comparable size will cost us way more than this grid. If you add the AFR portion, and say replicate *:4 , that's like saying you can take down 3 servers and still be guaranteed to have a node in the cluster with the file you're looking for. Please let me know if I'm wrong, and with that in mind, can you provide an example of how to do this on a cluster of 4 servers to start ?
Hi Pooya, Your idea is correct. For the example of how to do it, have you gone through our wiki documentation? http://www.gluster.org/docs/index.php/GlusterFS Let us know if you need any help. Krishna
Thanks, and awesome project!
