hi all, i manage a mpi cluster which nodes (on a gigabit private lan) have plently free space (~60gigas each one). i'd like to use this free space to backup stuff. i was thinking about to merge the free space into a single logical volume so users could copy (rsync, or whatever) their files there. openafs can do it but i've been told that his performance with big files (~1giga) is not good. do you have any idea what i could use to archive this target ?
I have 16 nodes gfs cluster for it built on GFS but afaik GFS is stable and usable only for red hat (for other distros there's openGFS which is imho different ) . Setting it up took me 2 days on Quality Assurance and one day on production . There's a very robust way of managing the cluster and whole software is very very nice ;) One thing that's rather expensive is fiberchannel SAN that is important when using GFS .. i found no other way to set it up that with EVA (or other SAN with FC) with one exported logical volume for 16 machines connected to it with brocade Fiber Channel switch ... but effectiveness of such thing is very big ;) regards. -- Wojciech Ziniewicz | jid:zeth@chrome.pl http://silenceproject.org | http://zetho.wordpress.com
