I'd like to have an active-active file system replication between two linux machines. The machines are not on the same network and are connected to each other via a VPN.
The link between the machines is around 7mbyte/sec, 10-30ms ping.
The file system is rarely written to (around 1gb/week) but often read from.
The problem is that servers go down from time to time. And I'd like the live server to push all the new data when the other server comes up.
I've tried glusterfs, but it seems it's tailored for a SAN solution. I couldn't make it push the new data.
