dm mpath: fail message ioctl if specified path is not valid
Fail the reinstate_path and fail_path message ioctl if the specified path is not valid. The message ioctl would succeed for the 'reinistate_path' and 'fail_path' messages even if action was not taken because the specified device was not a valid path of the multipath device. Before, when /dev/vdb is not a path of mpathb: $ dmsetup message mpathb 0 reinstate_path /dev/vdb $ echo $? 0 After: $ dmsetup message mpathb 0 reinstate_path /dev/vdb device-mapper: message ioctl failed: Invalid argument Command failed $ echo $? 1 Signed-off-by: Mike Snitzer <snitzer@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
