gfarm_agent - Gfarm Filesystem Metadata Cache Server
gfarm_agent [ options ]
gfarm_agent is a cache server for a Gfarm metadata server that can be
shared by multiple hosts and multiple users. The cache server greatly
improves performance and response time for a Gfarm filesystem by
reducing network communication to a distant metadata server.
Any number of gfarm_agents can be running on different nodes (or even
on the same node) at the same time. Consistency among multiple cache
servers and a metadata server is maintained.
