Commodity file systems trust disks to either work or fail completely, yet modern disks exhibit more complex failure modes. We suggest a new fractured failure model for disks, which incorporates realistic localized faults such as latent sector errors and block corruption. We then develop and apply a novel faultinjection framework, to investigate how commodity file systems react to a range of more realistic disk failures. We classify their failure policies in a new taxonomy that measures theirdoi:10.1145/1095810.1095830 dblp:conf/sosp/PrabhakaranBAGAA05 fatcat:k4inx3x2b5cl3pcwvylh2pcv4m
