Pinned topic Flashes (Alerts): IBM Spectrum Scale (GPFS) 5.0 levels: reading files compressed with lz4 may result in daemon or kernel crashes, or possible undetected data corruption

‏2019-03-22T20:10:33Z |

Abstract


IBM has identified an issue in IBM Spectrum Scale (GPFS) V5.0.0 through 5.0.2.3 levels, in which reading files compressed with lz4 from a node running V5.0.0 through 5.0.1.2 may result in daemon or kernel crashes. Attempts to uncompress the files may also result in errors or crashes (V5.0.0 through 5.0.1.2) or file system structure errors (5.0.2.0 through 5.0.2.3). Reading such compressed files might also result in undetected data corruption across any of the file systems.
