Dynamically increasing available storage space in a storage volume

A computer program product for dynamically increasing available storage space in a storage volume, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processor to cause the processor to perform a method comprising:

• receiving, by the processor from an application running within a system, a request for an expansion of a file within a predetermined volume of the system, where the file includes a database file and the expansion includes an addition of data to the file within the system;
• determining, by the processor, that a first amount of available space within the predetermined volume is insufficient to allow the expansion of the file within the predetermined volume of the system;
• expanding, by the processor, the first amount of available space within the predetermined volume to create a second amount of available space that is greater than the first amount of available space, in response to determining that the first amount of available space is insufficient, including:
• in response to determining a first predetermined keyword in the request, automatically formatting the predetermined volume of the system,
• in response to determining a second predetermined keyword and an indication of a file name mask in the request, automatically deleting files matching the file name mask within the predetermined volume of the system,
• in response to determining a third predetermined keyword in the request, automatically migrating files within the predetermined volume of the system, starting with least recently used files and ascending in order of file usage, until space to allow the expansion of the file within the predetermined volume of the system, as well as a buffer including an additional predetermined percentage of available space within the predetermined volume, is obtained within the predetermined volume of the system,
• in response to determining a fourth predetermined keyword in the request, automatically provisioning space from a free data pool to the predetermined volume of the system;
• and
• expanding, by the processor, the file within the predetermined volume of the system, utilizing the second amount of available space within the predetermined volume.

A system, comprising:

• a processor;
• and
• logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to:
• receive, from an application running within a system, a request for an expansion of a file within a predetermined volume of the system, where the file includes a database file and the expansion includes an addition of data to the file within the system;
• determine that a first amount of available space within the predetermined volume is insufficient to allow the expansion of the file within the predetermined volume of the system;
• expand the first amount of available space within the predetermined volume to create a second amount of available space that is greater than the first amount of available space, in response to determining that the first amount of available space is insufficient, including:
• in response to determining a first predetermined keyword in the request, automatically formatting the predetermined volume of the system,
• in response to determining a second predetermined keyword and an indication of a file name mask in the request, automatically deleting files matching the file name mask within the predetermined volume of the system,
• in response to determining a third predetermined keyword in the request, automatically migrating files within the predetermined volume of the system, starting with least recently used files and ascending in order of file usage, until space to allow the expansion of the file within the predetermined volume of the system, as well as a buffer including an additional predetermined percentage of available space within the predetermined volume, is obtained within the predetermined volume of the system,
• in response to determining a fourth predetermined keyword in the request, automatically provisioning space from a free data pool to the predetermined volume of the system;
• and
• expand the file within the predetermined volume of the system, utilizing the second amount of available space within the predetermined volume.
