Hello again Kern,
Sorry to be a pest, but current CVS as of this morning, after your post, is
still failing the same way it was before.
I have a totally different autochanger in place now to run the regress tests.
It is a two drive unit, a different brand than the previous tests I have run.
I can duplicate with this unit exactly what I was seeing before. These tests
are run against CVS as of this morning. I did a cold rebuild of the regress
tests to be sure and get the new code in place.
The problem again is that Bacula does the following:
* loads slot 2 into drive 1
* unloads slot 1 from drive 0
* tries to load slot 2 into drive 0
The problem is that there is no unload of slot 2 from drive 1 prior to
attempting to load slot 2 into drive 0. I do not see how this can be related
to mtx-changer, as mtx-changer only does what it is told. In this case
mtx-changer was never told to unload slot 2 from drive 1.
The mtx-changer log segments are below. These are contiguous lines in the
original file; I have interleaved a few comments to try and make it easy to
read.
