If you hit EOT, then by definition there's no room at the end of the tape. If you mean "then we can rewind to the beginnning of this record and write a DLE that we now know will fit", them amanda doesn't do that for the same reason it doesn't append -- we don't trust tape drives enough to do anything but write linearly. In addition, your statement isn't necessarily true. If you're using hardware compression, then a different DLE will compress with a different ratio, and may or may not fit in the number of blocks of the "failed" DLE. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
