Abstract

A technique for verifying the consistency of slice allocation metadata includes accessing, from user space of an operating system running on the data storage apparatus, a set of drivers running in kernel space of the operating system to obtain slice allocation metadata from the set of drivers, and identifying discrepancies in slice allocation metadata returned from the set of drivers on a per-file-system basis.
