Volume already exists error

Hi Community, 

I want to get familiar with Bareos and I am doing quite ok with it, but I faced an issue I can not solve out. I wonder if any of you faced this problem.

Setup: Bareos director and storage and postgresql are installed on one (bare-metal) server. The version is 21.

Sometimes I can see strange logoutputs and I was wondering what the solution can be, because I don't think it is a normal behaviour.

Does any of you have any hint what I should check to avoid this situation? Thanks a lot in advance.
