Karl, Please understand that while I have some bacula experience, I am not as much of an expert as some of the other people on this list. As such, my suggestions are based on my thoughts on the matter and not based on long, deep experience with bacula, or with issues specifically like yours.
What OS is your bacula SD and bacula director running on? What version of bacula are you using? Assuming the command is available on your OS, what is the output of 'lsscsi'? Please paste the definitions for your tape devices from bacula-sd.conf What happens if you eject the tape, and then reinsert it? What happens if you attempt to restore data from this tape, or another tape that was previously used? What happens if you stop bacula, change the device type back to st from the preferred nst, restart bacula, then attempt to restore data? ################### THE FOLLOWING SUGGESTIONS ARE DATA DESTRUCTIVE AND SHOULD BE RAN WITH A NON-BACULA TAPE THAT DOES NOT HAVE IMPORTANT DATA ON IT ################### What do you see if you take a scratch tape with no important data on it, insert this tape into the drive, stop bacula, start bacula's btape utility, and run the 'test' command? *Please note that all data on this tape will be erased! *Since you do have some new hardware, maybe initial testing like that done when first setting up bacula could reveal whether the tape drive / library are working the way we expect that they should be. Here are some resources on testing a tape drive, using btape, and troubleshooting tape system settings. btape utility manual entry: https://www.bacula.org/13.0.x-manuals/en/utility/Volume_Utility_Tools.html#SECTION001900000000000000000 Tape testing chapter from the problem resolution guide: https://www.bacula.org/13.0.x-manuals/en/problems/Testing_Your_Tape_Drive_Wit.html#blb:TapeTestingChapter Regards, Robert Gerber 402-237-8692 r...@craeon.net On Fri, Mar 22, 2024 at 8:56 AM MMag.
