Might be a hard-coded timeout in the mtx-changer script. In my experience, I found it best to activae the wait-for-drive function in the script. > So, it looks like it would still be preferable to run some command > inside Bacula to eject the tape so that it knows about the ejection, > rather than going through the external script. Well, Baculas way of handling autochangers is to use the external script, there's no way to do it more internal than that. The advantage is that it's rather easy modify the mtx-changer script to what you need with your setup. Arno > This might be a question > for the developers, but is there a simple way to do that?
