Hi Pann. See comments inline below.

Hello Guys,

I'm new to Bacula.  And it's my first time trying to config Bacula 7.4.0 with vchanger 1.0.1 for my home network.

I have configured Bacula and vchanger following the vchanger 1.0.1 documentation included in the rpm package (vchangerHowto.html)

My hardware setup is as below:

       |-SATA_Port_1 -| 2-slots |    < Multiple 2TB SATA harddisks, each 
 HOST -|              | hotplug |<== < formated with single ext4 partition
       |-SATA_Port_2 -| dock    |    < (with unique UUID) for the respective
                                     < filesystem to be used as magazines.

The above 2-slots hotplug dock will allow me insert or remove 2 physical SATA drives (and therefore, 2 magazines) at a time.

For each magazine, I intend to make each volume file to be 100GB.


Here is my host system software setup:

- Fedora 23

- Bacula 7.4.0 (installed from Fedora repository)
Both Bacula Director and Bacula Storage Daemon are installed on the same host
(above).  It will be used to backup other clients on the network.

- vchanger-1.0.1-1.el7.x86_64.rpm (downloaded from Sourceforge: https://sourceforge.net/projects/vchanger/files/RPM/)



I have the following questions and problem:

1.  With regards to using 2 magazines simultaneously, are the following correct?

/etc/bacula/bacula-sd.conf:
===========================

[root@deneb ~]# cat /etc/bacula/bacula-sd.conf | grep -v  "^[#]"

Storage {                        # definition of myself
  Name = bacula-sd
  SDPort = 9103                  # Director's port
  WorkingDirectory = "/var/spool/bacula"
  Pid Directory = "/var/run"
  Maximum Concurrent Jobs = 20
}

Director {
  Name = bacula-dir
  Password = "xxxxxxxxxxxxxxxx"
}

Autochanger {
  Name = SATA-vchanger01
  Device = SATA-vchanger01-drive-0
  Changer Command = "vchanger %c %o %S %a %d"
  Changer Device = "/etc/vchanger/vchanger01.conf"
}

Device {
  Name = SATA-vchanger01-drive-0
  Drive Index = 0
  Autochanger = yes
  Device Type = File
  Media Type = File
  Removable Media = no
  Random Access = yes
  Maximum Concurrent Jobs = 1
  Archive Device = "/var/spool/vchanger/vchanger01/drive0"
}

Messages {
  Name = Standard
  director = bacula-dir = all
}

/etc/vchanger/vchanger01.conf:
==============================

[root@deneb ~]# cat /etc/vchanger/vchanger01.conf | grep -v  "^[#]"

Storage Resource = "vchanger01"
User = bacula
group = tape
work dir = "/var/spool/vchanger/vchanger01"
logfile = "/var/log/vchanger/vchanger01.log"
log level = 3
bconsole = "/usr/sbin/bconsole"
bconsole config = /etc/bacula/bconsole.conf
default pool = "Scratch"

magazine = UUID:1fde15be-83a4-4b67-accc-378d5fa10ea7
magazine = UUID:412060d2-7be4-4719-8089-2ee6cfd28624

magazine = UUID:fa48ed8d-2e63-4c27-8670-c943822d2cd0



2.  I followed the vchanger documentation (vchangerHowto.html) to setup vchanger.

I have successfully configured udev and autofs.  udev is able to mount the filesystems when I insert the drives.  And, autofs is able to mount it to the mountpoint /mnt/vchanger

I have also successfully created volumes in the first 2 magazines.

Device "SATA-vchanger01" has 0 slots.
No slots in changer to scan.


Questions:
==========
2a.  Why did vchanger list and listmags spits out "device-enumerator" lines?

2b.  bconsole throws out the lines below when I issue "status slots".  Did I misconfigured something?

Device "SATA-vchanger01" has 0 slots.
No slots in changer to scan.

2c.  Also, when I issue "status storage" in bconsole, I get following:

*status storage
...
...
Device status:
Autochanger "SATA-vchanger01" with devices:
   "SATA-vchanger01-drive-0" (/var/spool/vchanger/vchanger01/drive0)

Device file: "SATA-vchanger01-drive-0" (/var/spool/vchanger/vchanger01/drive0) is not open.
    Drive 0 is not loaded.



I have searched Google and still not able to find out why / what's wrong with my setup.  Appreciate if someone can help me out.

Thanks in advance.
PanTor
