Systems and methods for using a thin arbiter node as a quorum decision maker in a distributed file system. An example method comprises receiving a write request with respect to a file, identifying a first data storage unit storing a first replica of the file and a second data storage unit storing a second replica of the file, determining that the first data storage unit is unavailable and that the second data storage unit is available, and in response to determining, using metadata residing on a thin arbiter node, that the second data storage unit contains at least on stale file replica, failing the write request to avoid split brain in the distributed file system.
