End-to-end checksum provides automatic detection and resolution of silent disk errors. Creation of checksums is enabled by default, but can be disabled through policy on a per VM (or virtual disk) basis if desired. In case of checksum verification failures data is fetched from another copy.
The disk scrubbing process runs in the background.
