Hi!
Our Autochcanger ( dell136T) is connected to four tape drives.
Two of the are older LTO-2 and the rest are LTO-3 capable drives.
How I define bacula-dir to understand that there are two of each
drives in same autochanger?
You have the bacula-sd definition right... BUT...
Bacula's current state means you can only use LTO3 tapes in the LTO3
drives and LTO2 tapes in the LTO2 drives.
Bacula has no way of knowing that you can use LTO2 tapes in the LTO3
drives. I've been requseting that functionality for a while, as we have
always planned to install LTO3/LTO4 drives in our robot when hardware
upgrade time happens.
The main stumbling block is really in bacula-dir
# Definition of LTO-2 tape storage autochanger
Storage {
Name = Autochanger
Autochanger = yes
Address = XXXXXX # N.B. Use a fully qualified name here
SDPort = 9103
Password = "supercalafragilisticexpialidocious"
Device = Autochanger # must be same as Device in Storage
daemon
Media Type = LTO-2 # must be same as MediaType in Storage
daemon
Maximum Concurrent Jobs = 15
}
As you can see, the mediatype is locked into the changer entry and
currently the only way to define LTO3 jobs is to create another changer -
which will probably cause database issues with "update slots", etc.
We are using bacula version 1.38.11-3.
bacula-sd.conf configuration:
Autochanger {
Name = Autochanger
Device = Drive-1
Device = Drive-2
Device = Drive-3
Device = Drive-4
Changer Command = "/etc/bacula/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg0
}
Device {
Name = Drive-1 #
Drive Index = 0
Media Type = LTO-3
Archive Device = /dev/nst0
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
}
Device {
Name = Drive-2 #
Drive Index = 1
Media Type = LTO-3
Archive Device = /dev/nst2
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
}
Device {
Name = Drive-3 #
Drive Index = 2
Media Type = LTO-2
Archive Device = /dev/nst1
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
}
Device {
Name = Drive-4 #
Drive Index = 3
Media Type = LTO-2
Archive Device = /dev/nst3
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
}
