There was an idea some years ago about having an additional layer on between a block device and whatever else is above it (filesystem or something else), that will just do bad block remapping. Maybe it was even implemented in LVM or IBM-proposed EVMS (the version that included in-kernel stuff too, not only the userspace management), but I don't remember details anymore. In any case, - but again, if memory serves me right, -- there was low interest in that because of exactly this -- drives are now more intelligent, there's hardly a notion of "bad block" anymore, at least persistent bad block, -- at least visible to the upper layers. /mjt
When I run 3dm2 (3ware 3dm2/tools/daemon) I often see LBA remapped sector, success, etc..
My question is, how come I do not see this with mdadm/software raid? 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
