Hi,
i cannot mount cifs shares on a NAS,trying from two sles 10 sp4 boxes (kernel 2.6.16.60-0.93.1-smp, 64bit, cifs-mount-3.0.36-0.13.20.1). I know that i could one or two months ago. The command i issue is:
======================================
pc52974:~ # mount -t cifs //nas/idg-2 /mnt/idg-2/ -o username=bernd.lentes,workgroup=scidom,rw
Password:
mount error(22): Invalid argument
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
In my syslog appears (after echo 1 > /proc/fs/cifs/cifsFYI to make the output more verbose):

Trying the same from a SLES 10 SP2 box works fine.
Any ideas ?

I found this: http://lists.samba.org/archive/linux-cifs-client/2007-November/002470.html
the problem seems to be quite similar…
Maybe you could try the suggestion from there:
echo 0 > /proc/fs/cifs/LinuxExtensionsEnabled

Hi,
unfortunately this didn’t help. But i did "echo 1 > /proc/fs/cifs/cifsFYI to make the output more verbose. Dmesg says:

This output does not seem to differ from what you already posted here. You used IP address this time, though.
What could be more helpful is the output from the SP2 machine. And see how the lines differ.
If it really worked with SP2, you could compare the /etc/nsswitch.conf , /etc/hosts files from the SP2 and SP4 boxes.
If it really worked with SP4 1-2 months ago, I’d check if cifs-mounts package changed in the last months (rpm -q --last) and how (rpm -q --changelog cifs-mounts) and if that’s relevant. But it may be the kernel, though…
(I had a long battle with Samba last week, where on a day, a valid samba configuration stopped working. Krb5 seemed to be guilty, and although I hate using not core SLES software, installed the krb5 package from opensuse 11.4 which fixed everything. So somethimes we must hack, unfortunately.)
But a packet capture with tcpdump could be more useful. Again, both SP2 and SP4, and see where it goes wrong.

That’s the only difference:

Pc52785 is the SP2 box, PC53200 is the SP4 box.
I changed the entry in pc53200 to 127.0.0.2, no improvement.

rpm -qa --last |grep cifs:
cifs-mount-3.0.36-0.13.20.1 Mon Apr 16 08:00:46 2012
But i think the problem appeared already before.
I also installed already some packages from Opensuse 10.1 for our SLES boxes, if you don’t find an appropriate for SLES … what else can you do ?
I tried on the SP2 box a mount to a Windows XP share, worked.
Maybe a change on our NetApp Fileserver ? I will aks the storage admin.
rpm -q --changelog -cifs-mount:

cution as the “root” user; PIDL based autogenerated code allows overwriting

I got back to this error again:
fs/cifs/connect.c: invalid transact2 word count
and after googling for it one more time, I found this:
https://bugzilla.redhat.com/show_bug.cgi?id=217532
It’s the unix extensions again. Check the NAS config / ask the NAS guy, if he has something like this.
