Short: "start a master server, a volume server, and optionally a filer and a S3 gateway",
Long: `start both a volume server to provide storage spaces
and a master server to provide volume=>location mapping service and sequence number of file ids
This is provided as a convenient way to start both volume server and master server.
The servers acts exactly the same as starting them separately.
So other volume servers can connect to this master server also.
Optionally, a filer server can be started.
Also optionally, a S3 gateway can be started.
