problem mounting dvd ISO

[cguan]

Hi,

I'm trying to mount a w2k8 dvd iso image on freebsd 7 using mdconfig and
mount -t cd9660. the commands appeared to be working fine but when I look at
the mount point I only see a readme.txt file reads:

"This disc contains a "UDF" file system and requires an operating system
that supports the ISO-13346 "UDF" file system specification."

code:
#mdconfig -a -t vnode /path/to/w2k8.iso -u 0
#mount -t cd9660 /dev/md0 /mnt
#ls /mnt
readme.txt


if I use mount_udf, it said "Invalid argument"
code
#mount -t udf /dev/md0 /mnt
mount_udf: /dev/md0: Invalid argument

However, mounting a CD iso image using the same way is fine.

How do I solve this problem? I have been googling for a couple of hours but
can fine an answer.

thanks,
Calvin

Hello everyone. I am using the --backup flag in rsync to save
incremental changes that rsync makes when I sync a directory on my
laptop with my remote server. Please look at my pastebin code:
http://pastebin.com/m16a3ce38On The problem is that I end up generating
an ***@davidkarapetyan.homeunix.com: directory on my laptop that
contains empty versions of all the directories that were backed up. In
short, it is a directory filled with empty sub directories. Furthermore,
I am unable to have $INC be placed anywhere other than within $TARGET,
no matter how I alter the code. Interestingly enough, I use a very
similar script on the server itself, with no issues. It seems that
rsync's remote backup scheme, with the --backup flag, is a bit borked.
Any suggestions?

Have you tried loading the udf module, e.g., kldload udf.ko and maybe the
udf_iconv.ko prior to trying the mount command?

yes, I did.

# kldstat -v | grep udf
4 2 0xc44bd000 7000 udf.ko
419 udf
5 1 0xc4498000 2000 udf_iconv.ko
423 udf_iconv
# mount -t udf /dev/md0 ../iso_mount/w2k8-amd64
mount_udf: /dev/md0: Invalid argument
#

Is it possible the udf version is too new that the freebsd doesn't support
it? I can mount it with my ubuntu 8.10.

thanks,
Calvin

I suspect you are correct here. I seem to recall some distant memory of when
it first made it's way into FreeBSD and even then it was out of date and
just barely worked. Maybe it doesn't have support for ISO-13346. Don't
really know the answer to this myself.
