Short: "start a server, including volume server, and automatically elect a master server",
|
|
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 are exactly the same as starting them separately.
|
|
|
|
So other volume servers can use this embedded master server also.
|
|
|
|
Optionally, one filer server can be started. Logically, filer servers should not be in a cluster.
|
|
They run with meta data on disk, not shared. So each filer server is different.
