The following explains key terms appearing in the present invention.
raid io: disk array input-output operations.
FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention. The execution subject in fig. 1 may be a memory management system for raid io.
As shown in fig. 1, the method 100 includes:
and step 140, monitoring the execution result of the raid io operation, and releasing the applied memory after the raid io operation is executed.
Optionally, as an embodiment of the present invention, the generating a memory parameter according to a category to which the raid io belongs includes:
calculating a management structure corresponding to each operation flow type according to the number of the strips of the operation flow type;
and calculating the memory size required by each class raid io operation according to the management structure and the corresponding class raid io operation execution data.
Optionally, as an embodiment of the present invention, the applying for a memory according to a memory parameter as a raid io operation and executing the raid io operation after the application is completed includes:
requesting a memory at the starting stage of the raid io operation process;
if the memory request is successful, constructing and initializing a management structure of raid io operation;
and if the memory request fails, storing the raid io request into the waiting linked list.
Optionally, as an embodiment of the present invention, the monitoring an execution result of the raid io operation includes:
collecting a raid io operation execution result;
if the execution result has a failure operation band, repeatedly executing the failure operation band;
and if the failed operation strip still fails to be executed after the repeated execution times exceed the preset times, storing the failed operation strip into the corresponding raid management.
In order to facilitate understanding of the present invention, the memory management method for raid io provided by the present invention is further described below with reference to the principle of the memory management method for raid io and the process of managing the memory for raid io in the embodiment.
Specifically, the memory management method for raid io includes:
and S1, classifying the raid io according to the operation flow.
And classifying different raid io operations, wherein the use amount of the memory is different due to different raid io operation processes. Since the raid data is accessed according to striping, each raid io operation is classified by the number of stripes of the flow.
And S2, generating memory parameters according to the category to which the raid io belongs.
Because the operation of the raid io flow is predictable, the memory usage of various io operation management structures and data caches can be calculated. Taking the write operation of raid as an example, because raid data is accessed according to striping. It is therefore assumed that three stripes of data are requested to be written. The memory management structures needed are: one TCB is used for managing a data structure of the IO operation, one TCB is corresponding to three SIO structures to manage the writing processes of three data strips, each SIO is corresponding to a plurality of IPKs, and each IPK manages the writing operation process of one data block; meanwhile, the system also comprises TCS structures and the like related to the io operation, structures of each stripe FSW and the like, and data structures of xor and the like required in each block operation; it is also possible to include some management structures for fault handling etc.
The operations with different strip numbers correspond to different management structures, and the memory occupied by each management structure is a fixed value, so that the memory size required by the raid io operations of different classes can be calculated.
S3, applying for the memory for the raid io operation according to the memory parameters, and executing the raid io operation after the application is completed.
Referring to fig. 2, requesting a memory at the beginning stage of the raid io flow operation, if the memory request is successful, constructing and initializing a management structure TCB of the raid io operation, and continuing the io flow; if the memory allocation fails, the memory of the system is already in a tense state. And (3) placing the io request into a waiting linked list, taking the io request out of the waiting linked list when the memory is released, continuing to request the memory, continuing the io flow if the memory is successfully released, and still placing the io request back into the request linked list if the memory is failed.
And S4, monitoring the execution result of the raid io operation, and releasing the applied memory after the raid io operation is executed.
Splitting the io operation into three stripes, and further splitting each stripe into an operation of pairing each block data. Since the management structure of each stripe and block operation has already applied for memory, it only needs to be initialized. After a certain stripe or block operation is completed, the memory of the management structure is not released.
And when the returned result is unsuccessful after a certain stripe or block of the io operation is finished, performing corresponding error processing according to the error code. If the error is a timeout or an intermediary failure, etc. The stripe or block needs to be retried, and at this time, all io management memory structures and data caches still exist and can be directly used. If the failure still occurs after the set number of retries or the error is a non-retriable error, an error code is returned to an upper layer, and the raid stripe with the error is recorded into the corresponding raid management. So as to perform management operations such as bad block management and disk offline.
If the io operation returns a non-retriable error or returns a retriable error, but the retrial failure exceeds a set number of times or all the stripes and the blocks return success, namely all the blocks of the raid io operation return final execution results, all the memories are released, and corresponding operation results are returned.

the memory calculation unit 320 is configured to generate memory parameters according to the category to which the raid io belongs;

and the memory calculation module is configured to calculate the size of the memory required by each class raid io operation according to the management structure and the corresponding class raid io operation execution data.
