Abstract
Techniques perform storage management. Such techniques involve: detecting a change of a size of storage space for a file system, the file system having one or more associated bitmaps, each active bit in the one or more bitmaps indicating data status in storage space not exceeding an upper size limit of the file system; in response to detecting the change, determining, based on the upper size limit, a first number of bits required for indicating the changed storage space; and in response to determining that the first number exceeds a second number of current active bits in the one or more bitmaps, allocating at least one additional active bit for the file system. Accordingly, the number of bits for indicating the file system can be dynamically adjusted based on the changes of the file system.
