Cache-FS sounds interesting. I'll have to check it out. --- Wayne Johnson, | There are two kinds of people: Those 3943 Penn Ave. N. | who say to God, "Thy will be done," Minneapolis, MN 55412-1908 | and those to whom God says, "All right, (612) 522-7003 | then, have it your way." --C.S.

GFS sounds like it might work, but I have not found anyone who claims to have done this on Google. I remember there use to be AFS which worked in a similar fashion. > > Guess I'm hoping to set something up where files will exist on both networks. When a file is opened, the network compares the local and remote file systems and the newest version is used. If the remote is the newest, it's transferred to the local as it is used so the local cache is updated and the next use will be entirely local. Am I dreaming? Another thing to try is Cache-FS as a front-end to NFS. A guy from RedHat did most of the work and they finally got it in mainline a few releases ago, but it should be in Centos/RedHat already as they were claiming the customers wanted it. So, you just dedicate a large partition on the remote site as a cache and then mount NFS through it. I'm not sure what kind of latency you'll get, but the speed of light is what it is.
