[Gluster-users] Geo-replication (v3.5.3)

[Paul Mc Auley]

One thing I've noticed is that you need to make sure that the SSH host
keys of _each_ of the slave bricks needs to be in the known_hosts of
each of the master bricks. Failure to ensure this can cause failure in
a non-obvious way.

Regards,
Paul
