Huh. I've been running Consul since 0.7 or so, and the only time any of this happened was my own fault.

Most of the problems I've had with Vault have been around it's Terraform provider which they've improved enough that it's not an issue anymore.

I think the only thing about Raft that folks don't realize is how disk hungry it gets, if you want fast write performance you gotta make dang sure all those fsyncs can keep up. Our largest Consul cluster today runs on storage-heavy boxes as it does ~500Mb/s of writes pretty much 24/7.

I use Consul w/ Vault today instead of the internal storage for Vault just cause Consul has really nice monitoring around some stuff that Vault doesn't (path-based stuff for the most part), I think the internal storage is a really good option for 90% of use-cases.
