Avoid out of space outage in a thinly provisioned box

A computer system for managing a plurality of free space in a thinly provisioned box, the computer system comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• determining a rate of consumption of the thinly provisioned box;
• determining the plurality of free space of the thinly provisioned box;
• calculating a time of consumption of the plurality of free space;
• based on determining that the time of consumption is below a threshold time of consumption value, increasing a dispatch and increasing a priority of a clean-up job, wherein increasing the dispatch deletes a plurality of dirty extents from the thinly provisioned box to increase the determined plurality of free space, wherein the priority of the clean-up job represents a priority for execution of a cleaning program on the thinly provisioned box, and wherein the clean-up job deletes the plurality of dirty extents from the thinly provisioned box to increase the plurality of free space;
• and
• based on determining the plurality of free space is below a critical level value, executing the clean-up job before allocating a new extent in the plurality of free space of the thinly provisioned box, wherein the new extent reduces the plurality of free space of the thinly provisioned box.

A non-transitory computer program product for managing a plurality of free space in a thinly provisioned box, the computer program product comprising:

• one or more non-transitory computer-readable tangible storage medium and program instructions stored on at least one of the one or more tangible storage medium, the program instructions executable by a processor, the program instructions comprising:
• program instructions to determine a rate of consumption of the thinly provisioned box;
• program instructions to determine the plurality of free space of the thinly provisioned box;
• program instructions to calculate a time of consumption of the plurality of free space;
• based on determining that the time of consumption is below a threshold time of consumption value, program instructions to increase a dispatch and program instructions to increase a priority of a clean-up job, wherein increasing the dispatch deletes a plurality of dirty extents from the thinly provisioned box to increase the determined plurality of free space, wherein the priority of the clean-up job represents a priority for execution of a cleaning program on the thinly provisioned box, and wherein the clean-up job deletes the plurality of dirty extents from the thinly provisioned box to increase the plurality of free space;
• and
• based on determining the plurality of free space is below a critical level value, program instructions to execute the clean-up job before allocating a new extent in the plurality of free space of the thinly provisioned box, wherein the new extent reduces the plurality of free space of the thinly provisioned box.
