Hi,I get from time to time errors when backup up via my LTO-9 autochanger. This happens mostly when I do a full backup (ca. 30 TB data), sometimes when using differential backup. I am using the updated mtx-changer-script by Bill Arlofski, as the one out of the box was always running in timeouts when tape changing was needed.This error popped up recently. And persisted now for several full backups, now additionally for a differential one. Anyone any idea where the problem is and how to solve it? Thank you. Cheers
Hello Dr. Thorsten Brandau, What does my script log at this time?Most likely the mtx unload command is failing due to an issue with the change/library. Just a guess of course, but a guess based on experience. :)
Also, thanks for letting me know you are using this script. I have no idea who has even tested it in the wild.Keep in mind, you can increase the logging level in the config file if necessary, but I am still going with an mtx changer error, and I think this might get logged, regardless.
And, who knows, it seems like you might also be reaching the Bacula SD's Device 'MaximumChangerWait' timeout, and my script is being killed by the SD. Perhaps sometimes the time it takes your library to change a tape is right on the edge of the default for this Bacula SD timeout threshold and all that needs to be done is to increase that timeout.
But as I read, I see that the default for this timeout is 5 mins, and your log paste seems to show that your SD kills my script at about the 8 minute mark. Close enough for horseshoes and hand grenades? Maybe but seems a bit off for computers. :)🤷
And, FYI keep an eye on the Gitlab repository because I have been making changes/improvements to it. ;) Best regards, Bill -- Bill Arlofski w...@protonmail.com
