This adds "remove" capabilities for the clustered environment. When a user initiates removal of a device from the array, a REMOVE message with disk number in the array is sent to all the nodes which kick the respective device in their own array. This facilitates the removal of failed devices. Signed-off-by: Goldwyn Rodrigues <rgoldwyn@suse.com> Signed-off-by: NeilBrown <neilb@suse.de>
