Storage is Cheap, so is Water - Don’t Waste it

Sign up or log in to save this to your schedule and see who's attending!

"Replication of data on different sites provides high availability, however, each copy adds more cost and latency. If you try to save money and only have 2 copies, it may lead to a situation where each copy claims to be a good copy and blame others as bad. This is called a split brain.

Thin arbiter volume just maintains information about the bad copy as a whole and not per file and acts as a quorum decision maker. This solution performs much faster than a three-way replica as it participates only in case of failure, only once. Thin arbiter keeps only one file of zero byte to keep information on good and bad copies. As a thin arbiter node does not participate in regular IO operations, it can be hosted on low-end servers or cloud, which saves money and effort.
