    dm raid: handle failed devices during start up · 0447568f
    Jonathan E Brassow authored
    The dm-raid code currently fails to create a RAID array if any of the
    superblocks cannot be read.  This was an oversight as there is already
    code to handle this case if the values ('- -') were provided for the
    failed array position.
    With this patch, if a superblock cannot be read, the array position's
    fields are initialized as though '- -' was set in the table.  That is,
    the device is failed and the position should not be used, but if there
    is sufficient redundancy, the array should still be activated.
