Abstract
Maintaining metadata consistency among storage devices failures, which includes: for each of a plurality of datasets: writing, on different storage devices of a respective write group, a respective plurality of copies of a respective dataset corresponding to a respective identifier, where at least one copy of the respective dataset remains readable after less than a threshold number of storage device failures within the write group; and responsive to recovering from a system interruption: generating a catalog of valid datasets based on one or more identifiers stored among readable storage devices of the respective write groups.
