ABSTRACT:
A method and related computer program product of preventing write corruption in a redundant array in a computer system, comprising detecting a write failure from a calling application to at least one disk of the redundant array, writing failure information to non-volatile storage; returning an I/O error to the calling application; reading the failure information from the non-volatile storage during the next system reboot; and reconfiguring the array to eliminate the failed disk.
