thats the pool definition: Pool { Name = AudioBackup Pool Type = Backup Recycle = no AutoPrune = no Volume Retention = 30 years Maximum Volumes = 100 Maximum Volume Jobs = 0 } |

st 9:0:0:0: [st0] Add. Sense: Warning - specified temperature exceeded gaves me the hint: After checking the server and watching the fans with a endoscopic camera and closed cover inside the rack: After starting the test, the speed of the fans goes up, but with increasing of the temperature, they lowered the speed instead of spooling up more. Checking the the controller shows some damaged capacitors. After replacing the caps and simulating hot air with a hairdryer, the speed of the fans is now linear to the increasing temperature. The btape "fill" test is now running well and stable with a thruput of around 280 MB/s. After finishing the test, I will do a backup. |

testting now with backup: Despooling elapsed time = 00:39:31, Transfer rate = 265.3 M Bytes/second backup successful. feature request: monitoring tape drive health like temperature ... |

There's nothing in the scsi protocol which can be handled by bareos to offer such requested feature. Maybe you want to investigate what tapealert tool can do with your hardware for you. |
