I've got pretty poor knowledge about high availability systems so I was
wondering how this should be handled, if J2EE containers could play a
role and if there is good practices to share/replicate datas (artifacts,
metadatas, indexes, user preferences, ...?).

How do you handle repositories storage with this solution?
It's not a real issue when considering cached repository but what about
internal release (use in distributionManagement) and private

Sharing a same NFS doesn't seem a good way because it adds a possible
"point of failure" (unless setting up a high available nfs server

Not sure that rsyncing repositories partition frequently is a better

Setting every archiva instance to mirror others isn't safe either,
especially in a failover context (once artifacts are deployed in first
archiva instance, they're never replicated to others until the first
fail and it will be to late).

I think we will follow your advice.

We're in the same case now but if we succeed, this could evolve in a
multilocated structure.
