<div>Hi,<br>I'm trying to come up with a working configuration for some machines as follows:<br>- each is a client and a server and can see all the other nodes' storage and its own<br>- each has 4 identical hard drives<br>
- replication (one or possibly two replicas)<br>- high availability (continues to function if one replicated node of a pair goes down)</div></div></div></blockquote><div><br>Replication implicitly also provides High availability. High availability may be needed in the presence of replication in any of the following cases:<br>
1. replication is being provided on server side instead of having replicate on client.<br>2. each server has multiple network links. High availability is useful in this scenario if there are any problems in the network, but the server process keeps running without any problems.<br>

<div><br><br>It's something like the example configuration with NUFA/unify, but with replication across nodes and HA too.<br><br>Any suggested configuration? Just a general explanation of the setup is fine.<br>All my efforts so far have resulted in error messages about dht anomalies with "holes=1, overlaps=1" in the logs. I'm using 2.0.0rc1.</div>
