Abstract: A computing device includes an interface configured to interface and communicate with a communication system, a memory that stores operational instructions, and processing circuitry operably coupled to the interface and to the memory that is configured to execute the operational instructions to perform various operations. The computing device monitors a current state of a distributed storage and task processing network (DSTN) management unit by periodically collecting metadata that is compared to a previously recognized similar state. The computing device facilitates returning a resolution to the DSTN management unit to modify the current state using corrective actions and the DSTN management unit is configured to automatically execute the resolution or to record the resolution. Recorded resolutions are later passed to operators assigned to the DSN.

Abstract: A distributed storage network (DSN) processes storage unit maintenance tasks on multiple tiers within the DSN. A master storage unit coordinates pending maintenance tasks when a DSN management unit, originally processing the pending maintenance tasks, changes its status to offline. The method includes the master storage unit aggregating pending maintenance tasks from corresponding DSN storage units into an ordered list of maintenance tasks, facilitating, based on the ordered list of maintenance tasks, coordination of a next maintenance task with a corresponding storage unit and directing execution of the next maintenance task by the corresponding storage unit.

Abstract: A multi-system dispersed storage network (DSN) comprises a first DSN system that includes a first plurality of storage units, a first plurality of dispersed storage (DS) processing units and a first set of management units and a second DSN system that includes a second plurality of storage units, a second plurality of DS processing units and a second set of management units. The first set of management units manages a first set of configuration data of the first DSN system. A first management unit of the second set of management units, when, in a first mode, manages at least a first configuration data of the first set of configuration data, in a second mode, manages at least a first configuration data of the second set of configuration data, and in a third mode, manages at least the first configuration data of the first and second sets of configuration data.

Abstract: A method for coordinating management of operation risks in a distributed storage network (DSN) that includes multiple distributed computing systems including DSN memories begins with a global coordinating unit receiving messages including metadata from managing units associated with the multiple distributed computing systems. The method continues with the global coordinating unit determining, based on the metadata, that storage units in one or more of the distributed computing systems are executing or planning to execute an operation that could result in data loss or data outage. The method continues with the global coordinating unit transmitting an alert, including a command to halt the operation at the affected distributed computing systems.

Abstract: A method begins by determining, by a local management unit of a first locally operated dispersed storage network (DSN) memory of a DSN, a DSN memory issue, where the DSN includes a plurality of locally operated DSN memories and at least one global DSN management unit, and where the plurality of locally operated DSN memories includes the first locally operated DSN memory. The method continues by determining whether the DSN issue is a global DSN issue or a local DSN issue. When the DSN issue is the global DSN issue, the method continues by determining whether the local management unit is configured as a DSN global management unit. When the local management unit is not configured as the global DSN management unit, the method continues by generating DSN operational issue information based on the DSN memory issue and sending the DSN operational issue information to the global DSN management unit.

Abstract: A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), the method begins by identifying, for data stored within a DSN memory, one or more encryption keys used to encrypt data stored within the DSN memory. The method continues by identifying, for data stored within a portion of the DSN memory requiring sanitization, a master key of the one or more encryption keys that encrypts all of the data stored within the portion to be sanitized. The method continues by determining, if the master key is not used to encrypt data stored outside of the portion to be sanitized. The method continues, if the master key is not used to encrypt data stored outside of the portion to be sanitized, by sanitizing the data stored within a portion of the DSN memory by erasing the master key.
