Abstract: A method for execution by a rebuilding module includes detecting that less than a pillar width number of encoded data slices of a common revision are retrievable from a set of storage units. A decode threshold number of encoded data slices are retrieved and decoded to reproduce a data segment. The data segment is encoded to produce at least one encoded data slice and storage of the at least one encoded data slice in the set of storage units is facilitated in accordance with the common revision when determining to rebuild the at least one encoded data slice. The data segment is encoded to reproduce the set of encoded data slices and storage of the reproduced set of encoded data slices is facilitated in the set of storage units in accordance with a new revision when determining to not rebuild the at least one encoded data slice.

Abstract: A method for execution by a vault management device of a storage network includes determining a failure impact level to vaults of the storage network based on a failed storage unit within the vaults, where the vaults include a first vault that is associated with a first set of storage units and a first decode threshold number, and a second vault that is associated with a second set of storage units and a second decode threshold number, and where the failure impact level is based on the number of non-failed storage units within each of the vaults. The method continues with determining a failure abatement approach based on the failure impact level. The method continues by with facilitating the failure abatement approach.
