Thereby instantly removing the benefits of LVM and making it almost impossible to extend the space by adding another drive when needed. To the OP, pvmove is perfectly safe as it does a copy;verify;delete on one small block of extents at a time. It also ensures that any new writes while pvmove is running go to the new drive, so you can still use the system while moving (try doing that with cp :). -- Neil Bothwick Interchangeable parts aren't.
