Hello,

There is no way to get two autochangers to work on the same Volumes. You can try but it is almost sure to fail, because it was not designed that way. You can potentially use the two autochangers with two separate pools, and get Bacula to use both of them. This (multiple drives with separate pools) was implemented for stand-alone drives, but it was never tested, because it was not needed after implementing autochangers.

If someone were *really* interested he/she would need to test it and correct any problems in the code. I am *very* busy implementing other new features that are very important so I would not be the person to do it.

Most people in your place would simply swap out his drive and put in a newer one with more capacity (unless you are already using LTO-7). Otherwise most other people would swap out the two autochangers and get a single one with more cartridges.

Best regards,

Hi,

If that is the case, no, I will not try and will mess with the code, others do that better.

But still, even if two changers cannot work with the same volume, they can still work with the same pool which is good enough for me.

And, changers are mechanical devices that sometimes break, having two means you can loose one and still do your job.

Cheers,

Hello,

As stated in the subject, how can one get two (identical) changers work together seamlessly in the same pool so when one has its tapes filled up the next will continue without intervention?

Thanks,
