That would be perfectly acceptable, as long as it would heal deterministically (last one wins, or renamed conflicting files)

Hmm, then I wonder how a high-availability scenario would work, if it is not allowed for a node to go down in a replica-mode setup...

This would then probably be the case :(
It's a pity, I liked the simplicity and straightforward setup of GlusterFS...
Any recommendations what I should/could try out instead?
