4 23:02:49 sernux4 kernel: raid1: sda4: redirecting sector 551968744 to another mirror The problem seems to have corrected itself. But how serious is this? Should I replace the disk a.s.a.p. ? Or is this "normal" behaviour that can be expected? Btw: The disk is only a couple of months in operation so still under waranty.
