No problem, here's my full bacula-sd.conf, only comments and passwords are removed: | Storage { | Name = tigersclaw-sd | SDPort = 9103 | WorkingDirectory = "/var/lib/bacula" | Pid Directory = "/var/run/bacula" | Maximum Concurrent Jobs = 20 | SDAddress = 10.1.0.1 | } | | Director { | Name = tigersclaw-dir | Password = <removed> | } | | Director { | Name = tigersclaw-mon | Password = <removed> | Monitor = yes | } | | Device { | Name = FileStorage | Media Type = File | Archive Device = /srv/bacula/file | LabelMedia = yes | Random Access = yes | AutomaticMount = yes | RemovableMedia = no | AlwaysOpen = no | } | | Autochanger { | Name = Overland-NEO2000 | Device = LTO1-Drive-1 | Device = LTO4-Drive-1 | Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d" | Changer Device = /dev/sg4 | } | | Device { | Name = LTO1-Drive-1 | Drive Index = 0 | Media Type = LTO-1 | Archive Device = /dev/nst1 | AutomaticMount = yes | AlwaysOpen = yes | RemovableMedia = yes | RandomAccess = no | AutoChanger = yes | Maximum File Size = 2GB | Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'" | Spool Directory = "/srv/bacula/spool" | } | | Device { | Name = LTO4-Drive-1 | Drive Index = 1 | Media Type = LTO-4 | Archive Device = /dev/nst0 | AutomaticMount = yes | AlwaysOpen = yes | RemovableMedia = yes | RandomAccess = no | Maximum block size = 1MB | Maximum File Size = 40GB | AutoChanger = yes | Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'" | Spool Directory = "/srv/bacula/spool" | } | | Messages { | Name = Standard | director = tigersclaw-dir = all | } JFTR: "tigersclaw" is the name of my server which runs (among other things) the Bacula director, storage daemon und also the client where the backup job in question comes from.

No problem either: | # lsscsi -g | [0:0:1:0] tape HP Ultrium 4-SCSI H63H /dev/st0 /dev/sg3 | [1:0:0:0] disk ATA Samsung SSD 850 2B6Q /dev/sda /dev/sg0 | [2:0:0:0] disk ATA WDC WD40EFRX-68W 0A82 /dev/sdb /dev/sg1 | [3:0:0:0] disk ATA WDC WD40EFRX-68W 0A82 /dev/sdc /dev/sg2 | [7:0:0:0] mediumx OVERLAND NEO Series 0616 /dev/sch0 /dev/sg4 | [7:0:0:1] tape SEAGATE ULTRIUM06242-XXX 1603 /dev/st1 /dev/sg5 | # > Note in general, if btape works then Bacula will work because the SD > uses the same subroutines that btape uses for reading/writing tapes. Well, that's what I expected and that's why I'm so puzzled about this error... > Consequently there may be some other problem.

Here's the trace file from the beginning of the job until the point where the first tape was full and Bacula got stuck: https://suchanek.de/temp/tigersclaw-sd.trace (47kB) And here ist what happend when I manually cancelled the stuck job (which worked) and try to do a "release LTO4-Drive" command in bconsole. (Which didn't work, i.e. Bacula got stuck here too.) https://suchanek.de/temp/tigersclaw-sd.trace.2 (3kB) I hope you can find anything usefull in these debug files, because I'm totally lost here...
