Processing device configured for data integrity testing utilizing replicated test metadata file
An apparatus in one embodiment comprises at least one processing device comprising a processor coupled to a memory. The processing device is configured to schedule generation of a point-in-time replica of one or more logical storage volumes of a storage system, to generate a test metadata file for a data integrity test to be performed utilizing the point-in-time replica, and to store the test metadata file in at least one of the one or more logical storage volumes for which the point-in-time replica is to be generated. The point-in-time replica may comprise a snapshot of a replication consistency group comprising the one or more logical storage volumes of the storage system. Scheduling the generation of the point-in-time replica of the one or more logical storage volumes of the storage system illustratively comprises initiating an asynchronous replication process for a replication consistency group comprising the one or more logical storage volumes of the storage system.
