The present invention is described in further detail.
Fig. 1 is a kind of flow chart of the WORM attribute update method of file provided in an embodiment of the present invention.As shown in Figure 1,
A kind of WORM attribute update method of file includes:
S10: when receiving write request, judge whether the corresponding file destination of write request has metadata write permission.
Specifically, when receiving the write request initiated by upper-layer service, then it represents that need to mesh corresponding to write request
It marks file and carries out data writing operation.After executing data writing operation to file destination, necessarily lead to the metadata of file destination
WORM attribute change, it is therefore desirable to the WORM attribute of file destination is updated.According to the method for the present embodiment, it is
The local metadata cache of file destination is updated, to update WORM attribute.Obviously, local metadata cache is updated then to want
Ask file destination that there is metadata write permission.Therefore, when receiving write request, write request pair is first determined whether in step at this
Whether the file destination answered has metadata write permission, if file destination has metadata write permission, executes S20.
S20: if so, after carrying out write operation to file destination according to write request, local first number of file destination is updated
According to the WORM attribute in caching.
Specifically, this step be file destination have metadata write permission on the basis of, according to write request to target
After file carries out write operation, the WORM attribute in the local metadata cache of file destination is updated.
It should be noted that metadata write permission uses incompatible lock mechanism in distributed file system, that is to say, that
In synchronization, can only at most there be a client executing to update the operation of local metadata cache, also, client executing is more
The operation of new local metadata cache and meta data server are executed the operation that the metadata of update is written into disk
Mutual exclusion.
S30: being sent to meta data server for the WORM attribute added up in the metadata cache updated in preset time, with
Just WORM attribute is written in disk meta data server.
Specifically, since the update of the WORM attribute to file destination is persistence operation, it is therefore desirable to right in disk
The WORM attribute of file destination is updated the update that can be realized to the WORM attribute of file destination.
Specifically, after preset time namely after client executing repeatedly updates local metadata cache operation, client
End sends metadata updates request to meta data server first, after the reception response for receiving meta data server, client
WORM attribute in the local metadata cache of accumulative update is sent to meta data server, while meta data server again by end
Metadata write permission is withdrawn, so that WORM attribute is written in disk meta data server.
For example, it is assumed that needing the data to be written of 10M to be written into file destination according to write request, client is being received
To after the write request, 1M data are write every time, then need to be implemented 10 write operations altogether.According to the method for the prior art, every execution
Write operation just needs to send a metadata updates request to meta data server, so that metadata will be when time update
WORM attribute is written in disk, then in this example, needs to send 10 metadata updates requests, first number altogether to meta data server
Needing to be implemented 10 times altogether according to server will be when the operation into disk is written in time WORM attribute of update.And according to the side of the application
After executing a write operation, it is slow first to update local metadata in the case where file destination has metadata write permission for method
It deposits, it is assumed that execute 10 write operations altogether within a preset time, the corresponding update for executing 10 local metadata caches operates, so
Client discharges metadata write permission afterwards, sends metadata updates request to meta data server, thus by tiring out in preset time
The local metadata cache that meter updates is sent to meta data server, so that meta data server is by the WORM attribute of accumulative update
Write-in is into disk.That is, method according to prior art, needs to be implemented 10 times and sends metadata to meta data server
The operation of request is updated, meta data server needs to be implemented 10 times and the WORM attribute of update is written to the operation of disk；And root
According to the method for the present embodiment, after accumulative execution repeatedly updates local metadata cache, one is sent to meta data server
The operation into disk is once written in WORM attribute by metadata updates request, corresponding meta data server execution.
The WORM attribute update method of file provided in an embodiment of the present invention, be to file destination carry out write operation after,
The WORM attribute in the local metadata cache of file destination is first updated, then will add up the local first number updated in preset time
It is sent to meta data server according to the WORM attribute in caching, so that WORM attribute is written in disk meta data server, with
Realize the update to the WORM attribute of file destination.In compared to the prior art, in the WORM attribute for updating file destination every time
When, then it synchronizes to meta data server and sends the WORM attribute updated, so that meta data server will belong to as the secondary WORM updated
Property write-in disk mode, this method can greatly reduce to metadata send update WORM attribute number and metadata clothes
Business device reduces disk I/O, improves the performance of calling interface to the number of disk write-in WORM attribute to reduce network overhead,
The stability and reliability of raising system.
The WORM attribute update method for present embodiments providing another file, on the basis of the above embodiments, into one
Step includes:
If it is not, then the WORM attribute of file destination is sent to after carrying out write operation to file destination according to write request
Meta data server, so that WORM attribute is written in disk meta data server.
It is and to judge the corresponding mesh of write request after receiving write request that is, method provided in this embodiment
When marking file without metadata write permission, metadata updates request is sent to meta data server in real time, and receiving
After the reception response of meta data server, send to meta data server when time WORM attribute of update, so as to Metadata Service
Device will be written in disk when time WORM attribute of update, so that when file destination does not have metadata write permission, in time
Ground updates the WORM attribute in disk when secondary update.

The time of the corresponding whole write operations of write request.
That is, method provided in this embodiment, is to detect that completing the corresponding whole of current write request writes behaviour
Make and then sends the accumulative WORM attribute updated to meta data server.It is understood that due to receiving write request
Afterwards, it needs to execute multiple write operation to file destination according to the write request, it is corresponding, need the local metadata to file destination
WORM attribute in caching carries out repeatedly updating operation, therefore, the preset time in the present embodiment be from receive write request to
Complete the time of the corresponding whole write operations of write request, that is to say, that the corresponding file to be written of a write request is whole
Be written to file destination and then send to meta data server the WORM attribute of the accumulative update in local metadata cache.
In this case, can reduce to a greater extent on the basis of ensureing the integrality that WORM attribute updates to metadata
Server sends the number of the accumulative WORM attribute updated, to reduce network overhead and disk I/O.
