Hello! I have a 3 disk RAID-5 array with one spare disk on two IDE controller. As I'm experimenting with kernel and drivers, sometimes my kernel doesn't detect one of the controllers and therefore marks one of the RAID disks as faulty. The RAID-5 is my root fs... Next time I boot the kernel with all disks detected, RAID starts rebuilding which takes a long time - pretty unconvenient for testing... Is there a way to quickly add the disk back to array without resyncing - something like 'mdadm --unfail'? :) D. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
