Running vault concurrently from two web servers

Can two copies of the vault server run at the same time on different servers against the same database? If this worked it would make an infrastructure reorganization we are doing easier. I can understand if it doesn't.

Best regards,

The quick answer is that this is NOT supported, since there is no transaction regulation if two Vault servers are updating the same repositories. It can cause database corruption.

With Vault 3.5 it is possible to configure two Vault servers, with each server communicating with a different repository. For instance Vault ServerA updates repositories 1 and 2, and Vault ServerB updates repositories 4 and 5. If you are using Vault 3.5.x I can send you instructions if you're interested in this.

We haven't tested this with Vault 4.0, and Vault 4.0 has an additional database, sgmaster, so it may or may not work with 4.0.

Thanks for your quick response. We have, in fact, upgraded to Vault 4.0. I will develop a more conventional migration plan.

Best regards,
