Just some examples... searching on google (silent data loss) some guys report silent loss, but the NEC study is usefull to support Jamiro report... http://www.necam.com/Docs/?id=54157ff5-5de8-4966-a99d-341cf2cb27d3 page 3) Silent data corruption Introduction There are certain types of storage errors that go completely unreported and undetected in other storage systems which result in corrupt data being provided to applications with no warning, logging, error messages or notification of any kind. Though the problem is frequently identified as a silent read failure, the root cause can be that the write failed, thus we refer to this class of errors as “silent data corruption.” These errors are difficult to detect and diagnose, yet what’s worse is they are actually fairly common in systems without an extended data integrity feature. -- Roberto Spadim Spadim Technology / SPAEmpresarial -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
