Hello,

Let's say I have 10 machines, each having 1TB of free disk space. They
communicate over a gigabit network.

I would like to create a fault-tolerant array from these machines and their
storage, that would match RAID6 in overhead and fault resilience.
That is, it should provide 8 TB of usable space and tolerate a 2-member
failure without data loss.

Does anyone know if any of the current distributed filesystems will meet these
requirements? Working/stable/non-experimental level code is preferred.

The simple and obvious solution is mdadm over AoE/iSCSI, but maybe there is
something else built with network awareness from ground up, that would be a
better choice?

-- 
With respect,
Roman
