The document summarizes the use of GlusterFS in Japan over the past year. It discusses how GlusterFS has gained visibility among other IT sectors and been introduced in the medical field due to government initiatives. It also outlines some difficulties in adopting GlusterFS due to outdated versions, meeting Japanese requirements for continuity of services, and supporting features like 3-way replication and multi-master geo-replication. The conclusion states that while GlusterFS saw increased adoption in Japan, there are still issues to address and requirements to meet to satisfy Japanese quality standards for services.
