I'm running 5.2.13 under Fedora 20; this is working fine for me. > Additionally I have set "Maximum Concurrent Jobs = 4" in all the relevant > places, but all this seems to do is allow multiple concurrent jobs run, > which I have tested and seems to work, but strangely, I was under the > impression that one job could write to one tape exclusively.

Any ideas here would be appreciated or clarity. Make sure to set "Maximum Concurrent Jobs" in the storage definition, too! > Autochanger { > Name = Qualstar > Device = Drive-1 > Device = Drive-2 > Changer Command = "/opt/bacula/etc/mtx-changer %c %o %S %a %d" > Changer Device = /dev/changer-sg2 > } Looks OK to me. > Device { > Name = Drive-1 # > Drive Index = 0 > Media Type = LTO6 > Archive Device = /dev/nst1 > AutomaticMount = yes; # when device opened, read it > AlwaysOpen = yes; > RemovableMedia = yes; > RandomAccess = no; > AutoChanger = yes > Maximum Spool Size = 100G > Maximum Block Size = 1032192 > Maximum Network Buffer Size = 65536 > Spool Directory = /var/spool/bacula ... > } Try adding Changer Device = /dev/changer-sg2 to both your Device definitions. In your bacula-dir.conf, you should have something like this: # Definition of LTO autoloader Storage { Name = LTOLIB Address = ... SDPort = 9103 Password = ... Device = Qualstar Media Type = LTO6 Autochanger = yes Maximum Concurrent Jobs = 6 } Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: w...@denx.de Beware of the Turing Tar-pit in which everything is possible but nothing of interest is easy. ------------------------------------------------------------------------------ _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
