PVFS向元数据服务器发送一个请求(图4中的步骤1、2),这会通知请求节点有关文件在各个I/O节点上的位置的信息。
PVFS sends a request to the meta-data server (steps 1 and 2 in Figure 4), which informs the requesting node about the location of the file among the various I/O nodes.
下面示例中,DB 2数据服务器节点的IP地址是9.126.84.161,端口为50000。
For the example below, the IP address of the DB2 data server node is 9.126.84.161 and the port 50000 is used.
元数据服务器将文件名转变为索引节点,文件大小,和Ceph客户端用于文件I/O的分段数据(布局)。
The metadata server transforms the file name into an inode, file size, and striping data (layout) that the Ceph client uses for file I/O.
