I am having trouble with the following setup, hope that somebody will be able
We have a couple of workstations and two file-servers. Let's just keep it at 2
workstations for now, because I can just add more clients later I guess. So
the workstations are called echo and reality, and the servers are dream and
I am wondering whether it is possible to have a unified filesystem between
echo and reality, using the nufa scheduler to keep things local as much as
possible, and at the same time to have afr running on the servers neo and
dream so that those guys each have a complete copy of the workstations (echo
I can get it to work with only afr, or only unify, but combining the two
somehow does not do it. The best I got so far was to have empty directories
on the servers.
Worst case is that I go with not doing the unified thing, but it would be nice
because it is so much faster and most of the time, files are just accessed
locally anyway. With only client side afr, nfs seemed to be faster (with
varying performance translators), and with server side afr, nfs and glusterfs
where about the same speed - with the big advantage of not having a single
point of failure. :)
Maybe this setup just doesn't make any sense at all ...
Well, hope somebody has some suggestions!
