Red Hat Bugzilla – Bug 8036
dump -0ufB /dev/ftape 1638000 /mnt2 fails to use /mnt2 as the bkup target
Last modified: 2008-05-01 11:37:53 EDT
I have been using dump on previous Linux releases w/o a problem 2.0.32
Pentium 2 200mhz MMX, TR-3 tape drive
1. /sbin/insmod <path>zftape.o OK
2. mt -f /dev/ftape rewind or fsf or retension OK
3. tar -cvf /dev/ftape /mnt2 OK
4. dump -0ufB /dev/ftape 1638000 /mnt2
At this point I have 2 mounted partitions: / = /dev/hda3 3 gig
/mnt2 = /dev/hdb2 1 gig
/mnt2 contains my 2.0.32 OS. ext2 file system
dump says it's backing up /dev/hdb3 to /dev/ftape and is finished w/
nothing dump'd to tape. (about 1 minute) At first I thought it was an
ftape problem but I have no problem w/ mt and tar. I'm not sure why it's
saying it is dumping the /dev/hda3 file system unless it isn't seeing
the /mnt2 parm and is somehow defaulting to the root file system. I've
tried different variations of the command dump -0 -u -f /dev/ftape etc.
I've also tried loading ftape.o, but I couldn't get tar or mt to work.
Let me know if you need more info, I'd be glad to provide any info you
What version of dump "rpm -q dump"? You might try the latest dump-0.4b11
from Raw Hide, as mamy bugs in dump have been fixed there.
I'm using dump 0.4b4-11. I'll check for the new version.
I just tried dump 0.4b11-2 w/ the same results. Seems like dump is ignoring
the last parm which is the file system to be backed up. It is trying to dump my
root file system, not /mnt2 With this version I get a write error 20 block also
that I didn't get in version 0.4b4-11.
Is /mnt2 is your fstab?
Does it work if you dump directly the device (dump 0f /dev/nftape /dev/hdb2)?
What tells the 'file' command applied to your (empty) dump?
I have reasons to believe this was fixed in the latest release of dump, 0.4b14
Could you try that one, available from http://dump.sourceforge.net and see if
your problem persists?
I've built dump-0.4b14 for Red Hat 6.2. Bug should be closed as soon as it's
verified that the package fixes the bug.
Did dump-0.4b1 from RawHide/SourceForgefix your problem?
closed due to lack of additional feedback.

I never received the email "Did dump-0.4b1 from RawHide/SourceForgefix
your problem?". Sorry I wasn't sure how to close out the bug report.
Yes, it did work. I believe I responded directly with Stelian.
Sorry for the misunderstanding. I am very thankful for the assistance.
