Hi, We have a cluster with 130 compute nodes with an NAS-type central storage under gluster (3 bricks, ~50TB). When we run large number of ocean models we can run into bottlenecks with many jobs trying to write to our central storage. It was suggested to us that we could also used gluster to unite the disks on the compute nodes into a single "disk" in which files would be written locally. Then we could move the files after the runs were complete in a more sequential manner (thus avoiding overloading the network). What was originally suggested (the NUFA policy) has since been deprecated. What would be the recommended method of accomplishing our goal in the latest version of Gluster? And where can we find documentation on it? We have seen the following links, but would be interested in any more pointers you may have. Thanks. http://thr3ads.net/gluster-users/2012/06/1941337-how-to-enable-nufa-in-3.2.6 http://blog.aeste.my/2012/05/15/glusterfs-3-2-updates/ http://www.gluster.org/2012/05/back-door-async-replication/ https://github.com/jdarcy/bypass -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Pat Haley Email: phaley at mit.edu Center for Ocean Engineering Phone: (617) 253-6824 Dept. of Mechanical Engineering Fax: (617) 253-8125 MIT, Room 5-213 http://web.mit.edu/phaley/www/ 77 Massachusetts Avenue Cambridge, MA 02139-4301
