Well, I am sorry to report that you did not read my message carefully enough: keeping the metadata at the end of the device is no more an option than keeping it at the beginning or in the middle: there is already data everywhere on the device. Also, the mdadm command you just gave is pretty explicit that it will wipe the local device. Thanks for pointing DRBD. -- Nicolas George
