RTFM:
This option will work only when
dumping to a file or pipe or, when dumping to a
tape drive, if the tape drive is capable of writing
variable length blocks.
You will probably have to issue a 'mt setblk 0', if your tape drive works with
this setting.

I take the upstream author (Stelian)'s above comment as indicative that this is not a bug, but misuse of the application. Closing NOTABUG. |
Description of problem: If dumping to a remote tape drive, compression does not work. For example (I've set the $TAPE and $RSH variables to allow auto-login): dump -u0 /tmp # works dump -u0z /tmp # does not work dump -u0j /tmp # does not work When compression is enabled, it gives errors along the lines of: DUMP: write: Invalid argument DUMP: write error 30 blocks into volume 1: Invalid argument DUMP: Do you want to rewrite this volume?: ("yes" or "no") DUMP: write: Invalid argument DUMP: write: Invalid argument I'm guessing it's receiving compressed positioning commands, in addition to the compressed data. Note that using compression to a local file works fine. Version-Release number of selected component (if applicable): dump-0.4b28-7 How reproducible: Always Steps to Reproduce: 1.dump to remote tape using -j or -z Actual Results: Dump fails with write errors Expected Results: Should have produced a compressed dump on the remote tape Additional info: I'm using a Seagate Travan 40 (ATAPI) drive, model STT3401A.
