Hi Doug. Hmm, have you tried with another tape? Also, double check
that the tape doesn't have the write protect tab engaged.
https://www.ibm.com/docs/en/ts3500-tape-library?topic=media-setting-write-protect-switch-lto-tape-cartrige
The only other thing I can think of is that the tape drive isn't
actually an LTO-7 drive. Try running lsscsi and posting the output here.

Hmm, that's odd that the mt commands work but the btape doesn't... I'm
wondering if the mt commands just aren't reporting an error. Try
writing a small volume with tar:

Hi Doug,
Try running the following and posting the output:
su -s /bin/bash bacula
ls -dl /dev/nst* /dev/sg*
groups
mtx -f /dev/sg3 status
exit
That will switch you to the bacula user, check the permissions of the
various devices, and attempt to run the mtx command as the bacula user.

The bacula user is definitely in the tape group.

I do believe this is probably a permission issue, but I'm not sure what the
correct way to resolve it is.

Hi Doug,
Is bacula running as root? On most setups it runs as the bacula
user, so you would need to make sure that that user is in the "tape"
group and has rw access to /dev/nst0.

Hello!
I'm setting up an HP autochanger with an LTO-7 drive with Bacula on Ubuntu
22.04 server at home. I've been able to run mt and mtx commands successfully
to erase a tape and change the loaded tape.
I've installed Bacula 13.0.1 using apt-get from the repo. I also installed
Bacularis for a GUI, but that isn't relevant to this issue. I've searched
Google and the mailing list archive and while I've seen others experiencing the
same problem from over a decade ago, I haven't found a fix.
I'm not sure if I am missing some udev rules or if it's something else.
When I try to run the btape test, I get this output.
./btape -c ../etc/bacula-sd.conf /dev/nst0

DeviceType = "Tape"
ArchiveDevice = "/dev/nst0"

ChangerDevice = "/dev/sg3"
ChangerCommand = "/opt/bacula/scripts/mtx-changer %c %o %S %a %d"
AlertCommand = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
MaximumFileSize = 100G
LabelType = "Bacula"
LabelMedia = yes

Description = "LTO-7"
Device = "LTO-7"
ChangerDevice = "/dev/sg3"

Any assistance would be greatly appreciated,
