Hi Andreas, thank you for the tip. I've looked into the kernel.log and found these entries:
2025-05-26T23:16:43.264361+02:00 gandalf kernel: [49612.006103] mpt3sas_cm0: log_info(0x31120439): originator(PL), code(0x12), sub_code(0x0439) 2025-05-26T23:16:43.264389+02:00 gandalf kernel: [49612.006153] st 1:0:0:0: [st0] Error b0000 (driver bt 0, host bt 0xb). … 2025-05-27T23:09:14.578491+02:00 gandalf kernel: [135560.892293] mpt3sas_cm0: log_info(0x31120439): originator(PL), code(0x12), sub_code(0x0439) 2025-05-27T23:09:14.578508+02:00 gandalf kernel: [135560.892324] st 1:0:0:0: [st0] Error b0000 (driver bt 0, host bt 0xb). I'm not sure what that exactly means, but some research and ChatGPT make me think that this may indicate a medium error, a hardware issue, or a cable/SAS connection problem. I've tested different tapes with the same error so i would rule out the medium error. The tape drive was replaced in November 2024 so I would rule that out too. Maybe a cable/SAS connection problem which has been magically resolved by the reboot. As I wrote I will have an eye on the next few backups hoping I can close this issue.
