Detailed Description
The core of the application is to provide a data writing method, a data writing device, a server and a computer readable storage medium of a storage system, so as to improve the data writing efficiency and avoid the problem of delay.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the related art, whether a block is reconstructed is recorded while processing results of metadata recording are synchronized among a plurality of controllers of a storage device, to prevent the same block from being processed multiple times by different controllers. In order to determine the bitmap of the effective area, a corresponding bitmap operation request needs to be issued in the data writing process, so that the flow of data writing operation is increased, and the data writing efficiency is reduced.
Therefore, the application provides a data writing method of a storage system, which is characterized in that the effective area setting information is added into the first stripe lock request to obtain a second stripe lock request, and the second stripe lock request is sent to the opposite end controller, so that the opposite end controller can process the lock request and the setting information after receiving the request once, and the corresponding request is not required to be received again, thereby reducing the steps of receiving the request, simplifying the data writing operation, and improving the data writing efficiency under the condition of recording an effective area bitmap.
The following describes a method for writing data in a memory system according to an embodiment of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a method for writing data in a memory system according to an embodiment of the application.
In this embodiment, the apparatus may include:
s101, creating a first stripe lock request for a stripe corresponding to data to be written;
this step aims at creating a first stripe lock request for the stripe to which the data to be written corresponds. The first stripe lock request is mainly used for locking a stripe, so that the stripe is prevented from being operated by a plurality of devices, and data is prevented from being used as data.
The local end controller executes the steps.
Further, the step may include:
step 1, receiving data to be written;
step 2, determining a stripe corresponding to the data to be written;
and step 3, creating a first stripe lock request for the corresponding stripe.
It can be seen that this alternative is mainly described how to create a stripe lock request. In the alternative scheme, data to be written is received, a stripe corresponding to the data to be written is determined, and a first stripe lock request is created for the corresponding stripe.
It is obvious that in order to avoid that multiple devices operate on the stripe, in this alternative, a first stripe lock request is first created for the received data to be written, so as to apply for the lock request, and lock the stripe.
Further, this embodiment in the present embodiment may include:
step 1, judging whether an effective area bitmap exists in a stripe corresponding to data to be written;
and step 2, if yes, sending a first strip lock request to the opposite end controller so that the opposite end controller can process the first strip lock request.
It can be seen that this alternative also includes directly sending the first stripe lock request. Mainly, when the corresponding stripe exists the corresponding effective area bitmap, the first stripe lock request is directly sent so as to directly perform corresponding processing. In the alternative scheme, whether a stripe corresponding to data to be written has an effective area bitmap is mainly judged, and if so, a first stripe lock request is sent to the opposite terminal controller so that the opposite terminal controller can process the first stripe lock request.
S102, adding the effective area setting information into the first stripe lock request to obtain a second stripe lock request;
on the basis of S101, this step aims at adding the valid region set information to the first request for a second request for a tape lock.
The effective area setting information is mainly used for setting an effective area of the data to be written so as to set a flag bit, and the corresponding position exists data is marked as the effective area.
In the prior art, the valid region setting information is mainly sent to the opposite end controller separately, so that the opposite end controller sets the bitmap of the valid region, so as to represent the bitmap as the presence data, and the bitmap is valid region data.
Further, the step may include:
step 1, coding the effective area setting information to obtain an effective area setting code;
and 2, adding the effective area setting code into the structure of the first strap-lock request to obtain a second strap-lock request.
It can be seen that this alternative is mainly illustrative of how the second request for a stripe lock is obtained. In the alternative scheme, the effective area setting information is encoded to obtain an effective area setting code, and the effective area setting code is added into the structure of the first strap-lock request to obtain a second strap-lock request.
S103, sending a second strip lock request to the opposite end controller so that the opposite end controller processes the first strip lock request and the effective area setting information in the second strip lock request, and sending a processing success message when the processing is successful;
on the basis of S102, this step aims at sending a second stripe lock request to the opposite end controller, so that the opposite end controller processes the first stripe lock request and the valid region setting information in the second stripe lock request, and sends a processing success message when the processing is successful.
It can be seen that this second request for a stripe lock can be sent to the peer controller through this step, so that the peer controller performs a corresponding process. That is, the present embodiment is mainly applied to a dual-end controller. The local end mainly sends corresponding processing requests to the opposite end so as to realize double-end control and improve the reliability of the control.
And S104, when a processing success message is received, executing data writing operation on the data to be written, and setting the effective area bitmap.
On the basis of S103, this step aims at performing a write data operation on data to be written and setting the effective area bitmap when a process success message is received.
It can be seen that, on the basis of successful processing of the request by the opposite end, the local end controller performs a write operation on the data to be written, and performs a setting operation of the bitmap again.
The successful processing message comprises setting information and lock information.
Correspondingly, when receiving the processing success message, executing the data writing operation on the data to be written, and setting the effective area bitmap, including:
step 1, when a processing success message is received, executing data writing operation on data to be written according to setting information of the processing success message;
and step 2, setting the bitmap of the effective area according to the setting information of the successful message.
It can be seen that this alternative is mainly to explain how the processing is performed. In the alternative scheme, when a processing success message is received, data writing operation is executed on data to be written according to the setting information of the processing success message, and setting processing is carried out on the bitmap of the effective area according to the setting information of the processing success message.
It can be seen that in this alternative, the writing process is performed first, and then the setting process is performed on the effective area bitmap, so as to obtain the effective area bitmap. Further, when the reconstruction operation of the storage device is performed, the range of the reconstruction operation is narrowed according to the effective area bitmap, and the efficiency of the reconstruction operation is improved.
In summary, in this embodiment, the valid region set information is added to the first stripe lock request to obtain the second stripe lock request, and then the second stripe lock request is sent to the opposite end controller, so that the opposite end controller can process the lock request and the set information after receiving a request, and does not need to receive the corresponding request again, thereby reducing the steps of receiving the request, simplifying the data writing operation, and improving the data writing efficiency under the condition of recording the valid region bitmap.
The method for writing data in a memory system according to the present application is further described below by means of a specific embodiment.
In this embodiment, the Io write flow may include:
step 1, preparing a stripe for applying a stripe lock, and searching a bitmap of a corresponding effective area according to the stripe;
step 2, judging whether the current stripe is already an effective area; if yes, executing the step 3; if not, executing the step 4;
step 3, coding the information of the effective area without setting to a strip lock application structure;
step 4, encoding the effective area setting information to a stripe lock application structure;
step 5, sending a request to the opposite-end controller;
step 6, decoding by the opposite end controller to obtain a locking request and a bitmap setting mark;
step 7, setting request processing;
step 8, waiting for locking information when the processing is successful;
step 9, locking request processing;
step 10, locking request processing is completed;
step 11, setting information is coded to lock information and sent back to the home terminal;
step 12, the local end decodes, processes the lock and the subsequent io flow, and processes the bitmap setting correlation.
Therefore, in this embodiment, the bitmap update is merged into the io writing flow, the set information and the lock information are combined and sent, so that the communication between the two double controls is reduced, and the normal io writing scene is not obviously affected. The queue queuing phenomenon in bitmap updating is omitted, and the bitmap updating mechanism is dependent on the io for processing and does not wait, but is updated once every time each io is written, so that the updating efficiency is improved.
Therefore, in this embodiment, the valid region set information is added to the first stripe lock request to obtain the second stripe lock request, and then the second stripe lock request is sent to the opposite end controller, so that the opposite end controller can process the lock request and the set information after receiving the request once, and the opposite end controller does not need to receive the corresponding request again, thereby reducing the steps of receiving the request, simplifying the data writing operation, and improving the data writing efficiency under the condition of recording the valid region bitmap.
