Thanks Alan root@backup2.iciti:~# mt -f /dev/st0 lock mt: invalid argument `lock' for `operation' Valid arguments are: - `eof', `weof' - `fsf' - `bsf' - `fsr' - `bsr' - `rewind' - `offline', `rewoffl', `eject' - `status' - `bsfm' - `eom' - `retension' - `erase' - `asf' - `fsfm' - `seek' root@backup2.iciti:~# mt --version mt (GNU cpio) 2.11 ... To be thorough, the bacula-sd init script should not only run the mt rewoffl and mtx unload commands; it should also error trap their output. I suspect that, when our autoloader and backup server are powered up at the same time, the autoloader does not finish initialising before the backup server runs the bacula-sd init script. In which case the mt and mtx commands are ineffective and SD finds a tape in the drive resulting in the tape getting Bacula status Error. More after I have tested error trapping the mt rewoffl and mtx unload commands.
