hi;

I tried to backup some Filesystems with a brand new DDS3 from HP (SCSI)
but shortly after the dump started
i get a message to put a new tape (#2 ) into the device. The Tape i used
is DDS3 and i did a rewind with mt !

This is what gets logged by syslogd:

Oct 29 18:15:01 www kernel: st0: Error with sense data: extra data not valid Deferred error st09:00: sense key Medium Error
Oct 29 18:15:01 www kernel: Additional sense indicates Track following error
Oct 29 18:15:01 www kernel: st0: Error on write filemark.

My device is /dev/{st0,nst0 nrst0}

I modified some little script from our Sparc/Solaris box simliar to this
...

TAPE=/dev/nrst0
FS1=/opt

/sbin/dump -0u -f $TAPE $FS1
Any Hints about Linux spcifics (additional Parameters or whatever) are
are welcome !

PS I know i could use other tools as well but i prefer dump/restore
.... so please no use this use that stuff ..

Thanks in advance

Ah ha -- there's your problem. Dump has no idea how big your tape is.
You have two options, depending upon which version of dump/restore you're
using. If you're using 0.3, use the -B flag and then tell it how big
the tape is in KB. If you're using the 0.4b series (currently 0.4b7), then
there's a -a flag which tells dump to keep writing until it finds the end of
the tape.

You can get the current versions of dump/restore at:

Good luck.

Thanks - i ftp'ed the latest dump/restore/rmt added '-a' and it seems to work
that way.
