I'll test it soon in a 2-node scenario, where nodes are on separate networks and max speed is limited by an optical link to about 100Mbps. Currently NFS shares accessed throught the link are OK (just a bit slower than local ones -- but we're speaking of two small labs: 10 PCs in one and 25 in the other). And it adds full replication (instead of just a cache) "for free", making only the diffs travel throught the slow link. Maybe it could take a long time after a "split brain" to resync. Their "appliance" supports exporting as samba share, but I don't know the granularity and how well it could be integrated in a domain. -- Diego Zuccato Servizi Informatici Dip. di Astronomia - Università di Bologna Via Ranzani, 1 - 40126 Bologna - Italy tel.: +39 051 20 95786 mail: diego.zuccato(a)unibo.it -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
