Claim:
A method comprising: in response to detection of a failure condition in a storage stack that includes a first host computer and a storage device, exporting data from the storage device to a plurality of additional host computers; validating the exported data using the plurality of additional host computers, including using at least two of the plurality of additional host computers to collectively perform, in parallel, a full file system consistency check of a file system that includes the exported data, including: estimating a first duration for validating a subset of the data corresponding to a volume of the file system using at least a first one of the plurality of additional host computers; estimating a second duration for validating the subset of the data using at least a second one of the plurality of additional host computers; determining that the estimated first duration for validating the subset of data is a shorter amount of time than the estimated second duration for validating the subset of the data; and in response to the determination, assigning the first additional host computer to validate the subset of the data.
