Yes, I'am using 20G for holding disk. I had two files produced by amdump each one 9G. The taper doesn't achieve streaming when write them to the tape (and the rate is around 4MB/s instead of 5.9MB/s which is nominal). I tried to write them manually with tar on the tape (aside from amanda). Tar behaves the same unless I increase the bloking factor to 128/256 when it reaches full streaming and the rate gets to 5.6MB/s. I also tried to increase the number of tapebufs (more than 20) (altough I realized that it doesn't buffer the communication between taper and tape device drive) and I got an error. I believe that it comes from shared memory allocation that has reached its per process limit (640K - which I think it's enough). Thanks for any help, Mihai. <<>> Does anyone know how to modify the buffering ot the taper so that I can achive <<>> tape streaming. I'm using an dlt8000 tape on an enterprise e250 sun server.
