From olc:
I just called for tape problems, and thought that a way has been found
to kill the persisting tar. It happens not!
While "kill %n; jobs" reports a success, the actual tar is still
there, tying up the drive. Its parent shell has gone due to either
previous logout or killed.
The exact problem is as the following:
I have tapes completely filled, with the last file incompletely
recorded. TK-50 tape drive apparently fails to return a physical "end
of tape" signal to tar when it reads all the way to the end. That
specific copy of tar simply sticks there, tying up the device, even if
the parent shell is killed. "ps" shows that "logout", "kill -n
process-ID" or "kill %n" does not help.
current solution: reboot
This problem has been presented to Steve in VAX Resource Center when
visiting the DEC-3100. No words have come back yet. I know that I
often raise bezarre problems, but is there an alternative ?
