Abstract
A storage controller is configured to implement an atomic storage operation comprising a plurality of separate storage operations on a non-volatile storage medium. The storage controller may store persistent indicators to identify data that pertains to the atomic storage operation. An invalid shutdown may occur before the atomic storage operation is complete. A restart and recovery operation comprises a first scan of the non-volatile storage medium to identify data of the failed atomic storage operation. A physical trim note is stored on the non-volatile storage medium to identify the data of the failed atomic storage operation. The data may be identified by media address. Storage metadata is reconstructed in a second scan, which excludes the data and/or operations of the failed atomic storage operation.
