yea! it is a testing server I use that is the same kernel as our main server... just for tests like these so we don't screw up .... I never run the real thing before I'm sure I know I've got it working on our test server. Well... what I did was: -------------------------------- # cat do_changes.sh #!/bin/bash -x umount /mnt/md0 read mdadm --stop /dev/md0 read mdadm --zero-super /dev/ide/host0/bus1/target1/lun0/part1 read mdadm -C -n 4 -l 1 /dev/md0 /dev/ide/host0/bus1/target1/lun0/part1 missing missing missing read ### end of script ### What do you think?
