A partition perhaps? A raid block? If it says that it can't be removed because it's in active use, busy, it's probably telling you the truth. I've had this happen a couple of times. In one case, it held a virtual machine with a partition I had mapped using kpartx, so I had to use kpartx to unmap that partition. I think the other time the LV was itself a PV, or else it was shared using gnbd. --force means, in my opinion at least, "Yes, I know what I'm doing. I understand why the system is saying I better not do this, but I want to force it to happen anyway". When it's used to mean "I don't understand what's going on, I don't know why this is a bad idea, but do it anyway", that sounds to me like a recipe for problems. -- Ray Morris support@bettercgi.com Strongbox - The next generation in site security: http://www.bettercgi.com/strongbox/ Throttlebox - Intelligent Bandwidth Control http://www.bettercgi.com/throttlebox/ Strongbox / Throttlebox affiliate program: http://www.bettercgi.com/affiliates/user/register.php On Sun, 11 Sep 2011 17:44:48 -0700 "Linda A.
