Abstract
A method for scrubbing a storage pool is disclosed. The method includes loading a scrub queue with a number of identifiers corresponding to a number of datasets, selecting a first identifier from the scrub queue, where the first identifier corresponds to a first dataset, initiating a scrubbing of the first dataset. The method further includes, upon receiving an indication of a requirement to pause the scrubbing, pausing the scrubbing of the first dataset, creating a bookmark recording a last location within the first dataset that was scrubbed before pausing the scrubbing of the first dataset, detecting at least one change to a storage pool, and performing a modification in response to detecting the at least one change to the storage pool.
