Problem: I have md0 - raid1 - /dev/sda1 + /dev/sdb1 + persistent-superblock 1 md0 happens to be my / partition. If I will insert another two disks in that box (/dev/sdd, /dev/sdc with /dev/sdc1, /dev/sdd1 being members of md0 RAID1 array, the disks are from another box..) the kernel will mess-up the things, by 'autodetecting' the newly added disks as md0, and not _my_ disks. If I could alter the superblock info on the newly added disks, well, that will be good. So far, no HOWTO, and no docs mention the existence of a tool like this (you can only query the superblock, and that is all..) Best regards, Sandu Mihai - KPNQwest Romania Network Engineer
