| 1. | It requests a file as usual , and the request goes to the underlying pvfs filesystem
像平常一样请求文件，请求被传送到底层的pvfs文件系统中。 |
| 2. | Pvfs is available as a linux kernel module and can also be built into the linux kernel
Pvfs可以作为一个linux内核模块使用，也可以编译到linux内核中。 |
| 3. | The system selects the pvfs parallel file system to increase the i / o performance of large - scale clusters
该系统采用了pvfs并行文件系统来提高大规模集群的i / o性能。 |
| 4. | Multiple i o nodes store pieces of the file any regular underlying filesystem like ext3 can be used by pvfs
多个i / o节点上存储了文件的各个部分（ pvfs底层可以使用任何常见的文件系统，例如ext3 ） 。 |
| 5. | To solve the key problems that bring low the availability of pvfs , the author proposes an original technique to rapidly backup and restore the file system
针对影响pvfs可用性的关键问题,作者提出并实现了一种系统快速备份和恢复技术。 |
| 6. | 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
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。 |
| 7. | Pvfs is a good example of an open source parallel filesystem ; disk performance of better than 1 gbsec has been achieved on linux clusters using standard ide hard disks
（ pvfs就是一个很好的开放源码并行文件系统；目前已经在linux集群上使用标准的ide硬盘实现了超过1 gb / s的磁盘性能。 ） |
| 8. | A good thing about pvfs is that it allows binaries meant for regular filesystems to run on it without modification - this is somewhat of an exception in the parallel programming arena
有关pvfs有一件好的事情：不需做任何修改就可以在其上运行普通文件系统的二进制形式这在并行编程领域多少是个例外。 |
| 9. | All this is transparent to the calling application ; the underlying complexity of making requests to all the i o nodes , ordering of the file s contents , etc . , are taken care of by pvfs
这些步骤对于调用应用程序来说都是透明的；底层对所有i / o节点发出请求的复杂性、获取文件的内容等等，都是由pvfs处理的。 |
