示例1: New
// New constructs a new Driver
func New(params DriverParameters) (*Driver, error) {
var conn *rados.Conn
var err error
if params.username != "" {
log.Infof("Opening connection to pool %s using user %s", params.poolname, params.username)
conn, err = rados.NewConnWithUser(params.username)
} else {
log.Infof("Opening connection to pool %s", params.poolname)
conn, err = rados.NewConn()
}
if err != nil {
return nil, err
}
err = conn.ReadDefaultConfigFile()
if err != nil {
return nil, err
}
err = conn.Connect()
if err != nil {
return nil, err
}
log.Infof("Connected")
ioctx, err := conn.OpenIOContext(params.poolname)
