Greetings, all
I'm brand-new to Bacula, and am trying to set up vchanger.sh using the
documentation at http://wiki.bacula.org/doku.php?id=removable_disk in
combination with the Bacula manuals. I'm running version 2.4 of Bacula
itself, and the back end is MySQL 5.1.x.
In production, this setup will use multiple USB disk drives, but for
testing I am using three logical volumes called d1, d2, and d3 to
represent my "daily" USB drive set.
I have created /etc/bacula/changer-usb-daily.conf with contents as
follows:
baculasd="changer-usb-daily"
baculasd_user=bacula
bconsole=/usr/bin/bconsole
magslots=20
maxdrive=2
mountpoint=/home/bacula/daily
statedir=/var/bacula/changer-usb-daily
One of the logical volumes is currently mounted at /home/bacula/daily to
simulate a USB drive having been mounted there by autofs. An "ls -l" of
that volume shows the following:
-rw-r----- 1 bacula bacula 2 2009-10-26 18:42 index
drwx------ 2 root root 12288 2009-10-26 17:42 lost+found

-rw-r--r-- 1 bacula bacula 0 2009-10-26 18:42 m02s020
In my /etc/bacula/bacula-sd.conf file, I have this section:
# Virtual changer for daily backups
Autochanger {
Name = changer-usb-daily
Device = d1
Device = d2
Device = d3
Changer Command = "/etc/bacula/vchanger %c %o %S %a %d"
Changer Device = "/etc/bacula/changer-usb-daily.conf"
}
Device {
Name = d1
Media Type = File
Device Type = File
Archive Device = /home/bacula/d1
LabelMedia = yes; # lets Bacula label unlabeled
media
RandomAccess = Yes;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = no;
AlwaysOpen = no;
DriveIndex = 0
}
Device {
Name = d2
Media Type = File
Device Type = File
Archive Device = /home/bacula/d2
LabelMedia = yes; # lets Bacula label unlabeled
media
RandomAccess = Yes;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = no;
AlwaysOpen = no;
DriveIndex = 1
}
Device {
Name = d3
Media Type = File
Device Type = File
Archive Device = /home/bacula/d3
LabelMedia = yes; # lets Bacula label unlabeled
media
RandomAccess = Yes;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = no;
AlwaysOpen = no;
DriveIndex = 2
}
Finally, in /etc/bacula/bacula-dir.conf I have this:
# A test daily job
Job {
Name = "daily"
Type = Backup
Level = Incremental
Client = marcus-fd
FileSet = "etc"
Storage = storage-daily
Messages = Standard
Pool = daily
Priority = 10
}
# For testing
FileSet {
Name = "etc"
Include {
Options {
signature = MD5
}
File = /etc
}
}
Storage {
Name = storage-daily
Address = marcus
SDPort = 9103
Password = "1C-tT2Ql6DGOQ0OG-t1RDtkL6LKWVb9CD"
Device = changer-usb-daily
Media Type = File
Autochanger = yes
}
# Daily pool
Pool {
Name = daily
Pool Type = backup
Recycle = yes
AutoPrune = yes
Volume Retention = 30 days
Volume Use Duration = 2 min
}
The short value for "volume use duration" is for testing.
When I try to run "label barcodes" as directed in the HOWTO, the Bacula
console responds with this:
*label barcodes
The defined Storage resources are:
1: File
2: storage-daily
Select Storage resource (1-2): 2
Connecting to Storage daemon storage-daily at marcus:9103 ...
3993 Device "d1" (/home/bacula/d1) not an autochanger device.
Device "changer-usb-daily" has 0 slots.
No slots in changer to scan.
I'm not sure why it's trying to get to /home/bacula/d1 rather than using
the vchanger.sh script.
What is particularly confusing to me is the distinction between the
mount point in the vchanger config file, and the three device
definitions in bacula-sd.conf. Originally I thought I should mount my
three logical volumes at /home/bacula/d1 through d3, respectively, but
then saw that a single mount point was all that could be specified in
the vchanger config.
The vchanger doc is written from the perspective of a single drive being
online at a time, whereas I will have three devices online at once and
need the system to rotate round-robin through them each night for the
daily incrementals (I will have a separate device for a weekly full
backup, but that's a different configuration problem).
I get the feeling I'm pretty close to a working configuration here, but
have misstepped in one place. I'm just not sure *where* I goofed. I
would appreciate any suggestions of what to look at next.
Thanks, and kind regards,
Scott
