I had found the last link, but it was a bit hard to follow since it was so LVM specific. Hopefully, the patches in the second link will be reasonably easily modified to apply to the 3.3.9 source, because that's my easiest avenue to get it running. And, the first link looks fabulous. When I get something working, I'll have to try some of those. Neat stuff. Hopefully I'll get some time to fool with it this week yet and if I get anywhere, I'll update everyone. -Rich
