Actually, the steps are: 1) invalidate the RAID 2) create a new, broken, RAID using the invalidatd disk 3) copy data to new RAID 4) delete md127 5) add other disk from md127 to md1 Or something to that effect. A "rename" option or even a "I_KNOW_WHAT_I_AM_DOING_JUST_KEEP_THE_SAME_NAME" option, which would be enabled by default when booting with sysresccd, would be nice. -- Joost
