Data storage method and apparatus of virtual machine, virtual machine, and storage medium

A virtual machine, comprising:

• one or more processors and one or more memories, wherein the one or more processors are configured for executing computer-readable instructions of the virtual machine stored in the one or more memories, and upon execution of the computer-readable instructions, the one or more processors are configured for:
• acquiring a starting instruction of the virtual machine, and loading a storage device according to the starting instruction;
• accessing metadata information recorded in first storage regions of at least two corresponding files in the storage device, and verifying the metadata information to obtain a verification result;
• in response to the verification result being normal, accessing data region bitmap information recorded in second storage regions of the at least two corresponding files;
• determining, according to the data region bitmap information, data storage states of the at least two corresponding files;
• in response to the data storage states of the at least two corresponding files being both normal, sending target data to the at least two corresponding files to perform data storage;
• during the sending target data to the at least two corresponding files to perform data storage, in response to existence of an abnormal file in the at least two corresponding files, continuing to send the target data to the abnormal file;
• and
• in response to a number of times of sending the target data to the abnormal file being greater than or equal to a threshold of number of times and the abnormal file not performing the data storage successfully, determining that a data storage path of the abnormal file is abnormal.

A non-transitory computer-readable storage medium storing computer-readable instructions that are executed by a processor, and upon execution by the processor, are configured for:

• acquiring a starting instruction of a virtual machine, and loading a storage device according to the starting instruction;
• accessing metadata information recorded in first storage regions of at least two corresponding files in the storage device, and verifying the metadata information to obtain a verification result;
• in response to the verification result being normal, accessing data region bitmap information recorded in second storage regions of the at least two corresponding files;
• determining, according to the data region bitmap information, data storage states of the at least two corresponding files;
• and
• in response to the data storage states of the at least two corresponding files being both normal, sending target data to the at least two corresponding files to perform data storage;
• during the sending target data to the at least two corresponding files to perform data storage, in response to existence of an abnormal file in the at least two corresponding files, continuing to send the target data to the abnormal file;
• and
• in response to a number of times of sending the target data to the abnormal file being greater than or equal to a threshold of number of times and the abnormal file not performing the data storage successfully, determining that a data storage path of the abnormal file is abnormal.
