Lustre is for many more than that. Yeah 2 mainly..

I'l have to check OpenSSI out to see what it's about. Seems interesting. Thanks Greg for your help, I'll be going for GFS2 it seems. > Greg > -- > Greg Freemyer > Litigation Triage Solutions Specialist > http://www.linkedin.com/in/gregfreemyer > First 99 Days Litigation White Paper - > http://www.norcrossgroup.com/forms/whitepapers/99%20Days%20whitepaper.pdf > > The Norcross Group > The Intersection of Evidence & Technology > http://www.norcrossgroup.com >
