Hi all, I'm currently trying to setup a backup system with bacula and a Dell TL2000 LTO4 library.
My Bacula server is a Debian Lenny install with 2.6.26-2-amd64 Debian
stock kernel. I backported Bacula 3.0.1 to Lenny from the "Experimental"
Debian repository.
The library is correctly recognized :
burp:/etc/bacula# dmesg|grep " 6:0" | cut -c 16-
scsi 6:0:0:0: Sequential-Access IBM ULT3580-HH4 89B1 PQ: 0 ANSI: 3
scsi 6:0:0:1: Medium Changer IBM 3573-TL 7.40 PQ: 0 ANSI: 5
scsi 6:0:1:0: Sequential-Access IBM ULT3580-HH4 89B1 PQ: 0 ANSI: 3
scsi 6:0:1:1: Medium Changer IBM 3573-TL 7.40 PQ: 0 ANSI: 5
st 6:0:0:0: Attached scsi tape st0
st 6:0:0:0: st0: try direct i/o: yes (alignment 4 B)
st 6:0:1:0: Attached scsi tape st1
st 6:0:1:0: st1: try direct i/o: yes (alignment 4 B)
ch 6:0:0:1: Attached scsi changer ch0
ch 6:0:1:1: Attached scsi changer ch1
st 6:0:0:0: Attached scsi generic sg3 type 1
ch 6:0:0:1: Attached scsi generic sg4 type 8
st 6:0:1:0: Attached scsi generic sg5 type 1
ch 6:0:1:1: Attached scsi generic sg6 type 8
The mtx script works well :
burp:/etc/bacula# /etc/bacula/scripts/mtx-changer /dev/sg4 list
0 /dev/nst0 0
1:BK0001L4
2:BK0004L4
5:BK0002L4
9:BK0003L4
12:CL0001L4
I setted-up bacula-sd as bellow :
Autochanger {
Name = lib-tl2000-1
Device = tape-burp-LTO4-1
Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg4
}
Device {
Name = tape-burp-LTO4-1
Drive Index = 0
Media Type = LTO4
Archive Device = /dev/nst0
AutomaticMount = yes;
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
Alert Command = "sh -c '/usr/sbin/smartctl -H -l error %c'"
}
Autochanger {
Name = lib-tl2000-2
Device = tape-burp-LTO4-2
Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg6
}
Device {
Name = tape-burp-LTO4-2
Drive Index = 0
Media Type = LTO4
Archive Device = /dev/nst1
AutomaticMount = yes;
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
Alert Command = "sh -c '/usr/sbin/smartctl -H -l error %c'"
}
but I can't handle the lib from bconsole :
*update slots
Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"
The defined Storage resources are:
1: filer-burp-storage
2: tape-burp-lto4-1-storage
3: tape-burp-lto4-2-storage
Select Storage resource (1-3): 2
Connecting to Storage daemon tape-burp-lto4-1-storage at
burp.eve:9103 ...
3306 Issuing autochanger "slots" command.
Device "tape-burp-LTO4-1" has 0 slots.
No slots in changer to scan.
So What's wrong in my config ??? This worked with bacula 2.4 !
The final idea is to handle backups with one drive, and duplicate tapes
with the other drive. If possible, I would do that in only one job, but
I don't know how to do that... I guess it is possible with bacula 3 ?
Note that I can configure the TL2000 to handle 1 or 2 "logical
libraries" :
- on 1 logical library mode, the library reports 2 drives an 1
autochanger lib,
- on 1 logical library mode, the library reports 2 autochangers, each
has one drive
I wondered the 2 logical lib is better suited for what I intend to do,
but maybe am I wrong ?
Thanks,
