Good morning, thank you for your reply.
The bacula user is definitely in the tape group.
root@dl160g11:/opt/bacula/bin# mtx -f /dev/sg3 status
Storage Changer /dev/sg3:1 Drives, 8 Slots ( 0 Import/Export )
Data Transfer Element 0:Full (Storage Element 1 Loaded):VolumeTag = ABT001L7
Storage Element 1:Empty
Storage Element 2:Full :VolumeTag=2018-2L7
Storage Element 3:Full :VolumeTag=ABT005L7
Storage Element 4:Full :VolumeTag=ABT012L7
Storage Element 5:Empty
Storage Element 6:Empty
Storage Element 7:Empty
Storage Element 8:Full
I do believe this is probably a permission issue, but I'm not sure what the
correct way to resolve it is.
