Solved md0 - device busy, can't delete

[balanga]

I created an md0 memory partition some few days ago, and find I can't delete it:

root@T530:/# mdconfig -d -u 0
mdconfig: ioctl(/dev/mdctl): Device busy

????

First, try to find out which process keeps that memory disk busy. You probably remember what you did with it, ps -ax may help. Still mounted? When you are sure it can safely be deleted, mdconfig -d -o force -u 0 will work.

You might also check the output of mount(8) to ensure it's no longer mounted: mount | grep /md

Actually that was the problem.
