Abstract: A storage network operates by: sending a slice verification request to a destination storage unit, wherein the slice verification request includes a nonce and one or more of: a slice identifier, the slice, a revision indicator, or a verification method indicator; receiving an integrity value from the destination storage unit; determining when the integrity value is verified by determining one of: when a hash of the slice and the nonce matches the integrity value; when a decrypted signature of the integrity value matches a hash of the slice and the nonce; or when the decrypted signature of the integrity value matches the slice and the nonce; and when the integrity value is verified, updating a slice assignment corresponding to the slice, wherein updating the slice assignment associates the destination storage unit with the slice and disassociates the source storage unit from the slice.

Abstract: Methods and apparatus for maintaining availability of critical information in a storage network that includes a plurality of storage units. In an embodiment, a processing module(s) of the storage network identifies critical information stored in one or more memory devices of a computing device. Critical information can include, for example, information required for operation of one or more storage units to perform data access operations. The processing module obtains the critical information from the one or more memory devices, and dispersed storage error encodes the critical information to produce one or more sets of encoded critical slices. The processing module further selects a set of storage units of the storage network and facilitates storage of the one or more sets of encoded critical slices in the selected set of storage units.

Abstract: A method for execution by a storage network includes receiving a request pertaining to a data object. Metadata associated with the data object is determined and used to identify data segments associated with the data object and a set of storage units associated with the data segments. Based on a set of query requests, a response is received from a storage unit from the set of storage units. When the response indicates a storage environment that is unfavorable as compared to predetermined performance metrics, the storage network facilitates migration of encoded data slices associated with the storage unit to another storage unit.

Abstract: A method begins by a computing device of a storage network receiving a data access request of a transaction regarding a data segment, where at least one data segment is dispersed storage error encoded into a set of encoded data slices that are stored in a set of storage units of the storage network. The method continues by executing the data access request. The method continues by generating a set of audit record data files regarding the execution of the data access request, where an audit record data file includes a source identifier, a target identifier, a unique identifier associated with the data segment, a timestamp, and a type code that indicates a type of storage network activity associated with the transaction. The method continues by storing the set of audit record data files in the storage network.

Abstract: A method includes dispersed storage error encoding a data object to produce a set of encoded data slices. The method further includes obtaining routing path performance information for a plurality of routing paths from the computing device to a set of storage units. The method further includes selecting a first routing path for sending a first subset of the set of encoded data slices, where the first routing path has a performance level greater than a first performance threshold. The method further includes selecting a second routing path for sending a second subset of the set of encoded data slices, where the second routing path has a performance level less than or equal to the first performance threshold. The method further includes sending the first and second subsets of encoded data slices to the set of storage units via the first and second routing paths for storage therein.
