Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In view of the above objects, a first aspect of embodiments of the present invention proposes an embodiment of a method of opening a file. Fig. 1 is a schematic diagram illustrating an embodiment of a method for opening a file according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:
s01, setting an object name of a file constructed based on the identification number and the serial number;
s02, receiving a file opening request sent by a client, and acquiring an object name of a file corresponding to the request, which is updated recently;
s03, reconstructing a new object name based on the identification number and the serial number of the object name which is updated recently, and responding the object name to the client to write new data; and
and S04, deleting the corresponding data of the latest updated object name in the storage pool, and responding to the client to finish deleting the old data.
In the present embodiment, an object name (inode. Index) is constructed using a file-unique inode identification number and an object serial number index, where the serial number index is a consecutive number from 0. Thus, the same inode identification number and consecutive different serial number indices constitute all data distributions of one file as objects that are consecutive one by one. When the metadata server MDS receives an open request with an O _ TRUNC identifier issued by a client, acquiring an object name with the largest serial number of a file corresponding to the request, constructing a new object name (inode. Index + 1) by using the identifier number and the serial number of the object name, responding the new object name to the client, and starting write operation and writing new data after the client receives the response of the metadata server MDS; and meanwhile, the metadata server MDS marks the last time of the old data failure of the file, and synchronously deletes the file when the client writes the file, so that the old data is cleaned. And after the deletion operation, the client is responded again to inform the client of finishing the deletion operation.
In some embodiments of the present invention, obtaining the name of the object requesting the latest update of the corresponding file includes: and acquiring metadata information of the file corresponding to the request, and acquiring the object name with the largest serial number based on the metadata information.
In some embodiments of the invention, reconstructing the new object name based on the identification number and the sequence number of the most recently updated object name comprises: adding one to the serial number of the object name which is updated recently to be used as a new serial number; a new object name is constructed based on the identification number of the most recently updated object name and the new serial number.
In this embodiment, when receiving an open request with an O _ true identifier issued by a client, the metadata server MDS obtains an object name with a largest file sequence number corresponding to the request, constructs a new object name (inode. Index + 1) by using the identifier number and the sequence number of the object name, and responds the new object name to the client.
In some embodiments of the invention, answering the object name to the client to write the new data comprises: based on the new object name, the metadata of the corresponding file is requested to be updated.
In this embodiment, the metadata server MDS needs to modify the file metadata of the dropped-disk when responding to the new object name of the client, because the file actual object index does not start from 0 at this time, and needs to record the start position of the new serial number index into the file identification number inode and drop the disk.
In some embodiments of the invention, further comprising: and recording the metadata information of the old data and the metadata information of the new data in a log and uploading the log to a server.
In this embodiment, in order to consider atomicity of the event, when processing the open request, the metadata server MDS needs to respond to the client and initiate the deletion operation in synchronization, where the start position and the end position of the object of the old data and the start position of the new data fall into the journal log.
In some embodiments of the invention, further comprising: and receiving a file reading request sent by the client, acquiring metadata information of a file corresponding to the request, and returning the metadata information to the client.
In some embodiments of the invention, further comprising: the client receives and reads data based on the metadata information.
In this embodiment, when the client requests the metadata server MDS to read a file, the metadata server MDS may obtain the enlightenment position of the object from the identification number, and start reading actual data from the object.
It should be particularly noted that, the steps in the embodiments of the method for opening a file described above can be mutually intersected, replaced, added, or deleted, and therefore, these reasonable permutation and combination transformations should also belong to the scope of the present invention, and should not limit the scope of the present invention to the embodiments.
