I have several machines (7) running fedora and would like to reduce the amount of external bandwidth I am consuming. I see that there were several attempts to setup mirrors, but those projects seem dead. I've used a squid proxy before, but that also has issues with different mirrors and ssl. Finally, I could run a clustered FS so that way any package that is downloaded on one will be available on another and if it should go offline, it will automatically re-sync when it comes back online.
Is there a simpler to configure and more correct option than using something like glusterfs?
