ThinProvision:Shrink the volume when file in the instance was deleted

Registered by Xiaozhen Qi on 2013-12-25

Thin provision means allocating the disk space once the instance writes the data on the area of volume in the first time.

However, if the files in the instance were deleted, thin provision could not deal with this situation. The space that was allocated by the files could not be released.

So it is necessary to shrink the volume periodically when the files are deleted in the instance.
