Hi there! Has anyone gotten GNU tar's multivolume option working on a 1/4" SCSI tape drive ? I'm trying to use this option on a Sun 3/160.. It seems like it doesn't know when it hits the end of the tape, and mistakes it for an IO error. I'd like to know if anyone has a fix for this, before I start hacking :-).

I have a version of pdtar that I modified to read a /etc/default/tar file like the tar on Xenix. It can get the volume size from the file to make multi-volume archives.

Well, I haven't used GNU tar, but last time I looked the SUN 1/4 in tape drivers are pretty broken w.r.t. EOM (end of media). IMHO I think a tape driver write should fail with ENOSPC when an attempt is made to write past the end of tape. The SunOs 3 and SunOs 4 drivers I tried just hung. Perhaps GNU tar relies on the error type? -- Ian Dall life (n). A sexually transmitted disease which afflicts some people more severely than others. idall@augean.oz
