Hallo Miteinander



Ich bin im Bezug auf Bacula / Backup auf meinem DLT 


Wechsler etwas weiter gekommen. Doch schwietere ich 


immernoch am Wechsler selber aber denke nurnoch was 


kleines vergessen zu haben..nur was ?...


Hier der fehler den ich bekomme beim Labeln von Bacula:



*label


Using default Catalog name=MyCatalog DB=bacula


Automatically selected Storage: DLT-0


Enter new Volume name: HomeData2


Enter slot (0 for none): 2


Automatically selected Pool: Default


Connecting to Storage daemon DLT-0 at cheef:9103 ...


Sending label command for Volume "HomeData2" Slot 2 ...


3301 Issuing autochanger "loaded drive 0" command.


3991 Bad autochanger "loaded drive 0" command: ERR=Child exited with


code 1.


3304 Issuing autochanger "load slot 2, drive 0" command.


3992 Bad autochanger "load slot 2, drive 0": ERR=Child exited with code


1. Label command failed for Volume HomeData2.


Do not forget to mount the drive!!!



You have messages.



Ausschnitt meiner bacula-sd.conf


Device {


Name = "DLT-0";


Media Type = DLT;


Archive Device = /dev/sa0;


AutomaticMount = yes; # when device opened, read it


AlwaysOpen = yes;


# RemovableMedia = yes;


Label Media = yes;


Hardware End of Medium = No;


Fast Forward Space File = No


BSF at EOM = yes;


# RandomAccess = no;


Autochanger = yes;


Changer Device = /dev/pass0;


# Changer Command = "/usr/local/sbin/chio-bacula %c %o %S %a %d";


Changer Command = "/usr/local/sbin/mtx %c %o %S %a"


# Changer Command = "/usr/local/share/bacula/mtx-changer %c %o %S %a %d"


# Drive Index = 0;


# Maximum Spool Size = 2gb


# Maximum Job Spool Size = 1gb


# Spool Directory = /backuptmp/spool/dlt-0


}



Auszug bacula-dir.conf



Storage {


Name = DLT-0


#Do not use "localhost" here


Address = cheef # N.B. Use a fully qualified name here


SDPort = 9103


Password = "1/qdqGCrBGWUaqU7G4CHRThJ32x5PC8rBnmgGkf3FsMS" #


password


for Storage daemon


Device = DLT-0 # must be same as Device in Storage daemon


Media Type = DLT # must be same as MediaType in Storage


daemon


Autochanger = yes


}



Hier noch ein paar generelle Informationen. Wie ihr sieht, 


hab ich mit dem Changer Command in bacula-sd.conf gespielt da 


es mit dem normalen mtx Command in der console geht aber bei 


Bacula nicht. Hab bislang gedacht es liege am Changer command 


nur sicher bin ich mir da auch nicht mehr.



Gruss und vielen Dank


Hannes
