Hello, we are using a Tandberg Autochanger with LTO3 tapes (400/800GB).
After Bacula reported the VolStatus "Full" after just saving about 260 GB, we checked the output of demsg an found the following: [ 7.806343] st 3:0:1:0: Attached scsi tape st0 [ 7.806345] st 3:0:1:0: st0: try direct i/o: yes (alignment 512 B) [ 3295.705344] st0: Block limits 1 - 16777215 bytes.

Sense: Medium not present We found a posting that suggested to define Maximum Block Size = 65536 Maximum Network Buffer Size = 65536 in bacula-sd.conf. But although we didn't forget to restart the Storage Daemon, the error appaers again and the only about 260 GB are used. Is this a problem of Bacula or of the st0 driver. Thanks for any suggestions or hints, Stefan ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable. Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
