thanks for all your input.
of course i took a look on all
http://en.wikipedia.org/wiki/List_of_file_systems#Distributed_file_systems
before posting here and wasn't satisfied with those i evaluated
(fault-tolerant).
it seemed to me that no project like riak implements a _real_ shared
nothing multi-master architecture, which is what i want when i have to
trust it with my data.
i took a deeper look on ceph, which is my top choice at the moment, but
it didn't prove itself production ready yet (which it doesn't claim).
@jeremiah: i'm really not looking for a SAN. i want the data to be
deployed in different datacenters. the problem is, that these are not
colocations, so i'm stuck with server-hardware they provide. and we
can't use things like CARP.
unfortunately our demand for capacity is increasing faster than
anticipated, so waiting for ceph to become stable isn't an option
anymore. we don't have human resources for developing a good fuse
bindings ourselves.
of course, if we don't find anything, we can simply scale out our
active/passive architecture we're running at the moment, but this gets
more and more complicated, the more servers we throw in.
that's why i'm looking for some beautiful and simple design that
minimizes the possibility of administrative failures.
cheers
