[Samba] Smbfs problems after upgrading from Woody to Sarge

[Sam Snow]

I earlier this week upgraded from Debian woody to sarge on a machine that
does a nightly backup to another machine via a samba share. Since then I
have had some issues with accessing that share with I believe are a result
of the upgrade. I upgraded the kernel at the same time to 2.4.27-1-686 #1
via apt-get, which might be the related to the problem. Smbfs is version
3.0.6-3 (http://packages.debian.org/testing/otherosfs/smbfs ).

I am looking for some advice as to how to proceed with further
troubleshooting.

Here is how I mount the share in fstab. I should move the user/pass to a
credentials file, but one thing at a time (this works):
/etc/fstab:
//wardrobe/backup       /backup smbfs
defaults,fmask=644,dmask=755,password=***,user=***       0       0

Once the share is mounted I am able to list directories, create and modify
small files (touch, echo, etc). I don't get any errors and things look
like they are working fine.

However, when I try to copy a ~200 MB file is when I get into trouble.

Error on the command line:
aslan:/backup/test# cp wardrobe.tar.gz.1 wardrobe.tar.gz_test123
cp: writing `wardrobe.tar.gz_test123': Input/output error

Cat /proc/filesystems

Looking through my boot logs, the only error that I can see is the following:

Sep 10 11:01:20 aslan modprobe: Note: /etc/modules.conf is more recent
than /lib/modules/2.4.27-1-686/modules.dep
Sep 10 11:01:21 aslan last message repeated 3 times


I have done a pretty complete Google search and a search of the archives
and not found anything that has helped. Anyone out there have any
suggestions? The machine that I am making the mount from is running the
same (up to date) version of Samba.

Thanks,
Sam
