I invite you to check out our product, Quobyte (www.quobyte.com). Not open-source, but a parallel high-performance POSIX file system, with split-brain safe quorum replication of all components, can also do erasure coding for files, with policy-based data placement, running on standard server hardware. We designed it to yield top performance both for (parallel) file system workloads and block storage workloads. So you can run VMs and databases on it with a performance better than any other partition-tolerant software storage system. The goal is to provide customers with a scalable automated general storage platform for all workloads, a la Google, but for real world applications.
