next in thread | raw e-mail | index | archive | help
I was attempting to back up my system with ft (as described in
the man pages) and the program hung. And I mean really hung.
I wasn't able to terminate the process with a "kill -9 pid_number".
I had to reboot to terminate the process. The error message on
the console read:
ft0: unrecoverable write error on block 3200
I am running FreeBSD 2.1.0 (<- I think... I did a net install in
April '96) and my tape drive is an iomega DITTO 420 (QIC 80) and
the tape is a DC-2120XL QIC80 formatted mini data cartridge. The
drive is daisy chained with the two floppies. The tape was brand
new (just out of the wrapper).
What I did to try to solve the problem: When I saw that the tar
was hung and that there was an error on the console, I tried to
^C out. Failing that I tried to kill the process. The ft process
would not die (I did manage to kill all of the parent processes,
including the login... And I was root at the time).
A possibly related incident (which if anyone knows if it is a
problem or not I'd like to know) is when I not ft the tape (to
try to see the label) I just get: " "
and the creation date (it was supposed to have the label:
"/ backup". It also will give the following 3 lines before and
after the label:
ftc0: output ready timeout
ftc0: input ready timeout
ftc0: input ready timeout
Is this indicating a problem?
Anyone know what is going on? Do I need a separate format command
for the tape before I try to tar something on it? I have searched
the faq, Handbook and the archives of mailing lists on the Web and
can find very little about this tape driver, so if I have missed
something, please let me know.
Also, one last thing, is this the type of thing one would submit as
a bug or not. I have not yet done so, but can file a bug report if
people think that it fits the area of problem reports.
Sorry this is so long. Thanks in advance for any help.
