Hey all,

I've got something strange going on here, looks like. Apparently Bacula
had trouble finding the end of the tape on this one. However, it is a
nearly brand new tape. The drive appears as if it may have needed
cleaning, and I wonder if it perhaps wrote a bad file mark at some point
because the drive was dirty (or somehow missed writing one at all). In
any case, something strange is happening. According to my catalog, this
volume contains 4 "volume files". However, btape appears to be able to
find more than this:

# /opt/csw/sbin/btape helios_DDS
Tape block granularity is 1024 bytes.
btape: butil.c:286 Using device: "helios_DDS" for writing.
btape: btape.c:368 open device "helios_DDS" (/dev/rmt/0cbn): OK
*scan
btape: btape.c:1630 Starting scan at file 0
1751 blocks of 64512 bytes in file 0
End of File mark.
2152 blocks of 64512 bytes in file 1
End of File mark.
2256 blocks of 64512 bytes in file 2
End of File mark.
1893 blocks of 64512 bytes in file 3
End of File mark.
542 blocks of 64512 bytes in file 4
End of File mark.
18 blocks of 64512 bytes in file 5
End of File mark.
1830 blocks of 64512 bytes in file 6
End of File mark.
2822 blocks of 64512 bytes in file 7
End of File mark.
btape: btape.c:1637 Bad status from read -1. ERR=btape.c:1636 read error
on /dev/rmt/0cbn. ERR=I/O error.

It looks like there are 7 "good" "files" on there, and that anything
after that is not in a good state, however, I know that only 4 of those
"files" are referenced in my backups. How can I fix this? At the very
least, I'd like to shelve this tape until its next use (in a few weeks),
and make try to make the catalog match the tape. Is bscan appropriate in
this circumstance? How safe is bscan on a tape like this?
