[Dump-users] Problems spanning tapes with dump

[Tom H. <tr...@ti...>]

Hi,

We have used a Sun DLT autoloader for years on our Solaris machines, 
using ufsdump to back up all the machines at our site.  We have now 
switched to a RedHat Linux 9 machine as our main fileserver, and I am 
having problems getting it to span tapes when I use dump for the backup. 
This is getting very critical, since I haven't had a good backup since 
the new system was installed a week ago.

Here's the setup:

-Sun Solaris machine with DLT autoloader
-the Sun machine runs a script in cron that starts a dump command on the 
Linux machine, like this:

       rsh -n $OBJECTHOST /usr/sbin/dump \
               -${backup_level} -u -f ${TAPEHOST}:${TAPEDRIVE} \
               $OBJECT                 >> $logfile 2>&1

Everything works fine, but when the Linux machine hits the end of tape, 
it gets this:

 DUMP: End of tape detected
 DUMP: Closing /dev/rmt/0hn
 DUMP: Volume 1 completed at: Sat Nov 15 00:11:02 2003
 DUMP: Volume 1 5814360 blocks (5678.09MB)
 DUMP: Volume 1 took 0:34:39
 DUMP: Volume 1 transfer rate: 2796 kB/s
 DUMP: Change Volumes: Mount volume #2
 DUMP: fopen on /dev/tty fails: No such device or address
 DUMP: The ENTIRE dump is aborted.

It's like dump has to send something to the operator, and can't.  In 
Solaris ufsdump, the "-l" switch takes care of that, and all ufsdump 
does is wait for the autochanger to load the next tape (the autochanger 
is in sequential mode), and continues on.

I downloaded the latest dump from http://dump.sourceforge.net, and I am 
using dump-0.4b34-1.

Am I missing something here?  Can you get dump to span tapes from a 
script?  HELP!  This is really getting critical...

-TIA
-Tom
