That will unload the drive (but use release and NOT unmount as that blocks the drive).

One day we should have it visible in the webui so you can based on this info look at drives and tapes and see how they behaved over time. You could unload the plugin and fall back to the old alert command in the SD definition and possibly write some script that does the hard work. Extending the TapeAlert to interpret the TapeAlert info is possible only there is no consumer of such events as the current plugin interface works on a per Job basis so you need some other plugin to react on an event. Again its all available so you can hack whatever you like but I would settle on releasing the drive at some time you think is convenient. If you play with the priorities of the Admin Jobs you may even be able to have it being suspended if it kicks in to early on any running Job. Not sure however if Admin Jobs fully play well with priorities etc. -- Marco van Wieringen marco.van.wierin...@bareos.com Bareos GmbH & Co.
