Abstract

See full text

Systems and methods for accounting for data whose rebuilding is deferred in a dispersed storage network. The methods include determining a number of compromised slices associated with a dispersed storage unit. The number of existing slices associated with the dispersed storage unit is also determined. A comparison of the number of compromised slices plus the number of existing slices associated with the dispersed storage unit, to a storage capacity, is performed in order to produce a capacity determination. Write requests directed towards the dispersed storage unit may be failed based on the capacity determination. For example, the DS unit may fail write requests, when a write request would cause the dispersed storage unit to exceed the storage capacity of the dispersed storage unit when taking into consideration existing slices as well as compromised slices that need to be rebuilt.
