:At Froscon (open source conference), I attended a talk about
:web-clustering. The speaker described a system with a dozen web-servers,
:each of which is connected to a central NAS via NFS to serve files. Of
:course the main task of the web-servers is to serve dynamic files. The
:speaker used NFS because it served his needs and was very easy to setup
:within minutes, unlike GFS.
:Just out of interest (without the time/boxes to try it out myself), do
:you guys think this is a "good" solution? I mean, does NFS handle a lot
:concurrent accesses well? I never used NFS...
:Hehe, I know, using HAMMERFS would be a terrible good solution ;-)
NFSv3 has no real cache coherency between clients. Theoretically
NFSv4 can but I think the concept of using a centralized filesystem
in a cluster is a bad idea generally even if it is the easiest
solution at the moment.
