Facebook runs several storage platforms at scale, one of them being GlusterFS - a distributed POSIX filesystem that runs well on commodity hardware. These systems can be challenging to run reliably at scale. As the amount of data, I/O rate, and number of clients go up, both problem diagnosis and system maintenance activities become increasingly difficult. In this talk, we'll talk about the tools and techniques that we use to administer and debug large distributed filesystems and show how others can leverage these techniques in their own environments.
