Nexus has a few users that are sharing the storage between separate Nexus instances directly via some shared backend like a SAN. Since Nexus uses just a regular m2 repo layout for storage, the options for clustering them are much greater and simpler.
-----Original Message----- From: Matthew Tordoff [mailto:[EMAIL PROTECTED] Sent: Friday, November 14, 2008 5:55 AM To: Maven Users List Subject: Highly Available Artifactory Hi all, I have recently been doing some investigation into making Artifactory Highly Available, and to be honest am having difficulty in finding an acceptable solution. To date the only solution I have found is having a 'cluster' of 2 Artifactory repositories which are load balanced. Each repository is then made to use the other as a proxy, so if a request for an artifact fails it searches in the repository of the other node. The problems I see with this approach are as follows: 1) There will be situations where losing one node will leave you with an incomplete set of artifacts. This will be when an artifact has been deployed to node X, and not yet requested from node Y - thus pulling it into it's local cache. 2) The second problem, similar to the first, is after a SNAPSHOT of artifact X has been deployed to node 1, and later requested from node 2, an updated version of that SNAPSHOT is then deployed to node 1. When a further request of that SNAPSHOT is made, the result of the request will be unknown - you could get one of the two different versions of the SNAPSHOT. 3) The security settings need to be maintained manually across the two nodes (potentially 3/4 if you include DR as well - and for our internal 20-30 different areas within the repository this is a huge overhead.) I have heard mumblings about the use of MySQL and it's replication abilities, however, have not seen any documented way to make use of these. If anyone has any further information on this topic then it would be greatly appreciated. Kind Regards, Matt Tordoff P.S.
