Abstract
Methods, computing systems and computer program products implement embodiments of the present invention that include initializing, by a processor executing a file system in communication with a block manager managing multiple storage regions on a storage device, a file system write cache to have a default cache size, the default cache size corresponding to a first storage capacity of a default number of the storage regions. Upon detecting that a current number of the storage regions that are not in use by the block manager is less than the default number, the file system write cache is resized to a reduced cache size that corresponds to a second storage capacity of the current number of the storage regions. While the file system write cache has the reduced cache size, the file system write cache can be resized back to the default cache size as unused storage regions become available.
