Abstract
A method for logging transactions which alters a file system stored on a secondary storage device is disclosed. The method includes the steps of writing data to a buffer in a buffer cache and logging the transaction in a log buffer residing on a primary storage device. A flag is set for the modified buffer, which is then added to a list of modified buffers. As the log buffer becomes substantially full, its contents are copied to a log partition residing on the secondary storage device. After an abnormal system shutdown, the contents of the log partition are copied to the buffer cache in order to restore the disk filing system.
