Abstract
Techniques involve detecting whether a transaction of modifying configuration data of a storage system is initiated, the configuration data being stored in a database and a buffered version being stored in memory independent of the database. The techniques further involve in accordance with detection that the transaction is initiated, building a data buffer to buffer a section to be modified, the data buffer being mapped to a storage sector of the memory in which the section is expected to be stored. The techniques further involve determining whether the transaction successfully completed and in accordance with a determination that the transaction fails to successfully complete, releasing the data buffer and aborting the transaction, without modifying the buffered version. Accordingly, the configuration data in the memory remains as the previous version and are not modified before the transaction is successfully completed, which makes it possible to abort the transaction.
