On further thought, might this not suggest that the linux raid system waits indefinetly for I/O error, before kicking out? If that is indeed the case, then if the use of the raid isnt time-critical, then maybe its a good thing to have tler enabled, just in case the disk is able to fix stuff? > > Justin. > > -- > To unsubscribe from this list: send the line "unsubscribe linux-raid" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
