I have recently moved to one Storage device per pool.
Why?
So each pool is on a different ZFS dataset.
Once I figured out the process for the first one, the rest was mostly waiting
for data to be copied.
I documented it here:

<https://dan.langille.org/2017/09/06/bacula-ran-out-of-space-moved-some-volumes-to-another-zpool/>
The final zfs layout looks like this:

<https://gist.github.com/dlangille/78811ba69b2a14f6c1e63c2b4bafc99e>
Here is the rough overview:
# in bacula-dir.conf
Pool {
Name = DiffFile
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 6 weeks
Storage = bacula-sd-01-DiffFile
Next Pool = Differentials
Maximum Volume Bytes = 10G
Maximum Volume Jobs = 1
Maximum Volumes = 300
LabelFormat = "DiffAuto-"
}
# Definiton of file storage device
Storage {
Name = bacula-sd-01-DiffFile
Address = bacula-sd-01.int.unixathome.org # N.B. Use a
fully qualified name here
SDPort = 9103
Password = "[redacted]"
AutoChanger = Yes
Device = VirtualDisk-DiffFile
Media Type = DiffFile
Maximum Concurrent Jobs = 27
}
# in bacula-sd.conf
# why do I do an autochanger? Some AutoChangers have multiple drives.
# It's easier to make them all similar.
# an example with 10 virtual drives is here:
https://gist.github.com/dlangille/ba787f6e6d838d2fbcc6ad9aad9afd55
<https://gist.github.com/dlangille/ba787f6e6d838d2fbcc6ad9aad9afd55>
Autochanger {
Name = VirtualDisk-DiffFile
Changer Device = /dev/null
Changer Command = /dev/null
Device = vDrive-DiffFile-0
}
Device {
Name = vDrive-DiffFile-0
Media Type = DiffFile
Archive Device = /usr/local/bacula/volumes/DiffFile
LabelMedia = yes
Random Access = yes
AutomaticMount = yes
RemovableMedia = no
AlwaysOpen = no
Autochanger = yes
Drive Index = 0
Maximum Concurrent Jobs = 1
Volume Poll Interval = 15
}
