Hi, I found a good document that introduces GFS implementation which is release in the middle of last year, however, many APIs has been changed since that. To have a good understanding of GFS, I'd like to get the latest version of it for your latest release, could you point to me the link? ps: the doc name is "Symmetric Cluster Architecture and Component Technical Specifications" Thanks, Michael -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster
