It's like cutting the branch you are sitting on. If you remove a device from a raid set, you may also clear the superblock for reusage. mdadm --zero-superblock /dev/hda1 or do it the hard way dd if=/dev/zero of=/dev/hda1 Check the other devices for proper bootloader installation. Otherwise your machine will refuse booting afterwards. You have to install the bootloader on every single device in the RAID set, to get it booting in the case of a disaster. -bernhard Am Di 07.05.2013 15:45 schrieb misha shiposh <netsferato@...il.com>: > Good day, guys! > > I was wander, if there are any faq or guides of how to totally destroy > raid > array? > > In my case I'll trying in a virtual sandbox to emulate this thing, > without > success... > > After I create software raid 1, I'll try to delete it with the > following > steps: > > Also this raid is root for my os, > > first delete one of disk > mdadm --manage /dev/md0 --fail /dev/hda1 > mdadm --manage /dev/md0 --remove /dev/hda1 > > then if I try to stop array md0 it says that it's busy.... no > wonder... > then I'll try to boot from removed disk and after that totally > removing > raid. > > and no success! > > stopping raid says it's busy, other way trying to delete the second > disk > without any result because of device is busy... > > is there any way to totally destroy raid ? > > > Thanks!
