There are ways to get bacula to load the same pool into 2 different
drives. I am not sure of the details because I do not do this with my
2 drive autochanger. I have 10 to 20 different pools depending on what
project and what kind of data I am backing up.

Most likely the job will fail and subsequent jobs will be blocked.

Manual intervention.

That should be fine. 2.4.1 is the latest bacula version. I am using
that because 2.4.0 gave me some problems with manual loads. Before
that I had 2.2.8 running for 6 months without any problem. I am using
64 bit gentoo though.
