BTW, with vchanger the two usb drives should not be devices
themselves. They are represented as magazines that are swapped out
when you issue update slots. The only reason to have more than 1
device is concurrency. This however does not fix your issue.. Sorry.

It is treated in the same way as a tape magazine in that respect. Each
magazine (USB drive) has its own unique set of volumes. Therefore you
must first label the volumes in each magazine using label barcodes, else
there won't be any usable volumes in the slots, just "blank tapes".
Once both drives have had their volumes labeled, whenever you swap
drives you will have to issue an update slots command in bconsole to
inform Bacula of which volume is currently "inserted" into each slot.
Also note that when swapping drives it is best to manually update the
status of the last volume written to in each pool from Append to Used.
Otherwise, Bacula will try to select that volume when the next job runs
after the drives have been swapped. That is not a bug, it is by design.
I believe it eventually times out and then selects another volume, but I
have found it makes more sense to mark those volumes Used anyway,
particularly if you use VirtualFull or Migrate jobs.

[Bacula-users] vchanger, two drives
Hello,
I am trying to configure bacula to use vchanger for offsite backups.
Basically I'd like to be able to swap USB drives every week and take them
offsite. The vchanger howto does not state whether I should run *label
barcodes *for each magazine. Could someone please clarify what operations
should be performed to configure two drives?
bacula-dir.conf relevant config:
Storage {
Name = OffSiteChanger
Address = mfile.merus.local-sd
Password = "snip"
Device = OffSiteChanger
Media Type = File
Autochanger = yes;
}
bacula-sd.conf relevant config:
Autochanger {
Name = OffSiteChanger
Device = OffSiteChanger-drive-0
Device = OffSiteChanger-drive-1
Changer Command = "/usr/local/bin/vchanger %c %o %S %a %d"
Changer Device = "/etc/bacula/removable.conf"
}
#--- drive 0 of the OffSiteChanger autochanger
Device {
Name = OffSiteChanger-drive-0
DriveIndex = 0
Autochanger = yes;
DeviceType = File
MediaType = File
ArchiveDevice = /var/lib/bacula/OffSiteChanger/0/drive0
RemovableMedia = no;
RandomAccess = yes;
}
#--- drive 1 of the OffSiteChanger autochanger
Device {
Name = OffSiteChanger-drive-1
DriveIndex = 1
Autochanger = yes;
DeviceType = File
MediaType = File
ArchiveDevice = /var/lib/bacula/OffSiteChanger/1/drive1
RemovableMedia = no;
RandomAccess = yes;
}# ...
vchanger config:
changer_name = "OffSiteChanger"
work_dir = "/var/lib/bacula/OffSiteChanger"
logfile = "/var/lib/bacula/OffSiteChanger/OffSiteChanger.log"
Virtual_Drives = 1
slots_per_magazine = 4
magazine_bays = 1
automount_dir = /opt/bacula/removable
magazine = "UUID:1125820e-3163-41d0-b571-36818eea5a78"
magazine = "UUID:8a672f1d-9f79-4b68-8260-8285eeb6a1d8"
With this configuration when I unplug one drive, plug in the second drive,
and run *update slots *bacula says this:
*update slots
Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"
The defined Storage resources are:
1: File
2: Archive
3: OffSiteChanger
Select Storage resource (1-3): 3
Enter autochanger drive[0]: 1
Connecting to Storage daemon OffSiteChanger at mfile.merus.local-sd:9103 ...
3306 Issuing autochanger "slots" command.
Device "OffSiteChanger" has 4 slots.
Connecting to Storage daemon OffSiteChanger at mfile.merus.local-sd:9103 ...
3306 Issuing autochanger "list" command.
Volume "OffSiteChanger_0002_0001" not found in catalog. Slot=1 InChanger set
to zero.
Volume "OffSiteChanger_0002_0002" not found in catalog. Slot=2 InChanger set
to zero.
Volume "OffSiteChanger_0002_0003" not found in catalog. Slot=3 InChanger set
to zero.
Volume "OffSiteChanger_0002_0004" not found in catalog. Slot=4 InChanger set
to zero.

I expected it to link the volumes to the new slots. What am I doing wrong?
Thanks,
Greg
