Hi,
I think it could be useful for you to look into "Maximum Volume Bytes" 
and "Maximum Volumes" Pool directives.
For example, I have a 1.4TB raid array where I want to use at most 1TB 
for bacula storage.
I have created a "File" pool like this:

# File Pool definition
Pool {
     Name = File
     Pool Type = Backup
     Recycle = yes
     AutoPrune = yes
     Volume Retention = 30 days
     # 40x25 = 1TB
     Maximum Volume Bytes = 25G
     Maximum Volumes = 40
}

Every volume in the File pool is named FileVolumeXXX, where XXX is a 
number (001, 002, ... 040).
Maybe you could create a similar pool for each disk, ensuring no more 
that the disk capacity is used by Bacula.

Just my 2 cents.
