/rant I swear, Amanda has given me nothing but grief since 3.3.6 -> 3.4.x.
My last two monthly amvault --latest-fulls have given me this error message, which from my barely-literate read of the source code, is an error from get_device(). Previous amvaults worked. My amanda.conf and tapelist can be found at https://drive.google.com/drive/folders/0B_vw5EcgO15lXzJwQVk3UXpkTUE but... before asking anyone to do a deep-dive in there, can anyone give me hints as to what I might try to narrow the scope of the problem? I am not looking forward to trying an strace. I did, to ensure sanity of the destination robot (the source is a VTL), do an amtape -otpchanger="HP_G2" vtl update" (my config is "vtl") No problems. The amvault command line is amvault -q --latest-fulls --dest-storage "tape_storage" vtl
