Bug #1667: disklabel / disklabel64 change needs reboot / disk change
http://bugs.dragonflybsd.org/issues/1667

Author: Thomas Nikolajsen
Status: Closed
Priority: Normal
Assignee: Alex Hornung
Category: 
Target version: 


Changing disk label from disklabel to disklabel64 format
or vice versa needs reboot (or disk change, eg natacontrol detach / attach).

This has worked without reboot earlier,
as described in disklabel(8) & disklabel64(8);
problem was introduced with devfs as I remeber.

Problem seems to be that in kernel disklabel survives
erasure of label on device (disklabel -W .. / dd if=/dev/zero of=DISK ..)
