No, it will not move any devices that already exist. It will either insert into the chain in the first hole it finds, or append to the end of the chain. This way, if you have drives sda through sdd and you remove sdb, then when you do an add, the new drive will take the now vacant sdb slot. For the common case of wanting to replace a failed drive, this is the perfect behaviour. -- Doug Ledford 919-754-3700 x44233 Red Hat, Inc. 1801 Varsity Dr. Raleigh, NC 27606
