A method for maintaining consistency among metadata elements (MDEs) of a logical object, includes: configuring a child MDE to include a correlation value uniquely indicative of a parent MDE. The parent MDE includes a reference to the child MDE; determining an order of performing at least two write operations included in a transaction related to the logical object: at least one write operation with respect to the parent MDE and at least one write operation with respect to the child MDE; the determined order assures that the child MDE is indicated as existing and includes the first correlation value, as long as the parent MDE exists; upon a first access to the parent MDE, subsequent to the transaction, verifying consistency between the parent MDE and the child MDE, using the first correlation value; and deleting the parent MDE if the verifying of consistency is unsuccessful.
