Hello, Well, I am not sure I can answer all your questions. I usually don't give much user support any more (too big a workload), but this subject is coming up more and more as users have more complicated setups. It sounds like you have a pretty large and sophisticated setup, which makes things even more difficult.
Basically Bacula was not designed to handle changing Storage devices. Doing so can get the Media table out of sync with the Storage table, then certain functions don't work too well. If you do delete Storage devices and perhaps add them, that is generally where problems come in. Also, if you try to use multiple Storage definitions in the SD that point to the same Device or which are part of the same Autochanger (possibly shared), you are going to run into a lot of problems that are simply due to the fact that the original design did not envision handling those cases. You should be able to add new Storage devices with no major problems providing you restart Bacula after doing so. If you do delete a Storage or change its name, you will need to delete all records associated with volumes written on that device or somehow manually update them to point to some new Storage device. Changing the code is a lot of work, and it is probably not even possible for Bacula to "figure out" what new storage device should be used in place of an old one. Also, I am mostly concentrating on the Enterprise code where we have implemented multiple shared Autochangers and such. That required a pretty big rewrite. It is hard to give you advice, because first, I have never really been able to reproduce any of the problems that are coming up for users, and second the exact advice depends on your setup, and understanding that take a lot more time than I have. If you can create a simple case where something goes wrong, I don't promise anything except to say I will look at it. I would need a very precise step by step process that shows how to create the problem. The best way to do that would be to send Dir and SD config files, along with a script that runs Bacula, possibly modifies some config parameters, restarts Bacula and clearly shows the problem. With something like that (i.e. something reproducible) I can hopefully find the problem and find a solution that either fixes it or prints much better messages telling you how to fix it. I recommend making any such submission in a bug report as emails get buried in my Inbox very quickly and thus effectively lost :-( Best regards, Kern On 04/05/2013 02:55 PM, Bugbear wrote: > Hello, > > Thanks for your answer. > > Let me explain the situation.
