Data sharing system, data sharing method and non-transitory computer-readable recording medium for data sharing program

A data sharing method carried out by a data sharing system in which a plurality of computer systems share data by communication, each computer system comprising:

• a physical computer that provides a virtual environment to execute an application;
• and
• a storage system that provides a volume to the virtual environment together with a storage device of the physical computer, the method comprising:
• a first step in which each of the plurality of computer systems stores data of an own computer system in the volume of an own computer system;
• and
• a second step in which each of the plurality of computer systems acquires data of another computer system from the other computer system and stores the data in the volume,
• wherein the second step comprises a third step in which, when each of the plurality of computer systems cannot acquire the data of the other computer system from the other computer system, the data of the other computer system is acquired from a different computer system than the other computer system and the data of the other computer system is stored in the volume,
• wherein each of the plurality of computer systems operates a monitoring container that acquires own monitoring data, which is a monitoring result of an operating situation of the own computer system, and another computer data acquisition container that acquires other monitoring data, which is a monitoring result of the operating situation of the other computer system, from the other computer system, and
• wherein the other computer data acquisition container mounts the volume provided for each of the other computer systems, which are other monitoring data acquisition destinations, to store the other monitoring data.

A non-transitory computer-readable recording medium for a data sharing program to cause each computer to function as each computer system of a data sharing system in which a plurality of computer systems share data by communication, each computer system comprising:

• a physical computer that provides a virtual environment to execute an application;
• and
• a storage system that provides a volume to the virtual environment together with a storage device of the physical computer, the data sharing program causing each computer to execute:
• a first procedure to store data of an own computer system in the volume of an own computer system;
• and
• a second procedure to acquire data of another computer system from the other computer system and store the data in the volume,
• wherein, when the data of the other computer system cannot be acquired from the other computer system, the second procedure comprises a third procedure to acquire the data of the other computer system from a different computer system than the other computer system and stores the data of the other computer system in the volume,
• wherein each of the plurality of computer systems operates a monitoring container that acquires own monitoring data, which is a monitoring result of an operating situation of the own computer system, and another computer data acquisition container that acquires other monitoring data, which is a monitoring result of the operating situation of the other computer system, from the other computer system, and
• wherein the other computer data acquisition container mounts the volume provided for each of the other computer systems, which are other monitoring data acquisition destinations, to store the other monitoring data.
