I get it - you wanted to prevent your OS experimentation from activating and possibly writing over your VG. I can understand why vgexport seemed like a solution, but it only prevents activation and removes references from local LVM configuration (and prevents booting when th!

So, physically disconnecting (or powering off) the disks is the best way to prevent that. -- 	 Stuart D. Gathman <stuart at bmsi.com> Business Management Systems Inc.
