Abstract
A data storage system non-disruptively transitions from using a ring-based write log to using a pool-based write log for buffering data being written to persistent secondary storage. The system initially creates the pool-based write log based on contents of the ring-based write log, and begins to mirror updates of the ring-based write log to the pool-based write log to establish synchronism. Subsequently, and based on an update flag indicating that an update process for the system has not yet completed, the system continues to mirror updates of the ring-based write log to the pool-based write log to maintain synchronism therebetween. Subsequently, and based on the update flag indicating that the update process for the system has completed, the system commences exclusive use of the pool-based write log and making the ring-based write log available for eventual removal.
