mount cifs does not work after SP2 upgrade

netzpks · August 7, 2013, 12:04pm

Hi Forum,

this mount was working on SLES11 SP1
mount //server/share /mnt/share -o username=user,password=password,uid=1000,gid=1000,workgroup=WG,file_mode=0330,dir_mode=0770

after SP2 upgrade:
mount error(2): No such file or directory
Refer to the mount.cifs(8) manual page …

???

Thank you for your support

mount //server/share/FOLDER … does not work!

mount //server/share … OK

Do SLES11 SP1 & SP2 refer to the server (where you’re trying to mount
from) or the client (mount to)?

I think you mean client and if so, what OS is server running?

Your follow-up message also says //server/share works but
//server/share/FOLDER doesn’t - since that conflicts with the above
report was that the case with SP1?

HTH.

Hi Simon,
thank you, for your help.

I try to describe:
our SLES11 SP1 Server connects to the network share //fqdn/sharename/foldername (like above described)
yesterday i upgraded our SLES11 SP1 Server to SLES11 SP2. Everything went fine.
Only the mount cifs behavior has changed.
Now it is possible to connect to //fqdn/share but not to //fqdn/share/foldername

if i try to connect to //fqdn/sharename/foldername i get the error
mount error(2): No such file or directory
Refer to the mount.cifs(8) manual page …

Hi netzpks,

this may have been a regression in the CIFS code (client side). I don’t have a test system at hand atm, but will check once I have access to my testbed again.

Can you verify the versions of both cifs modules (“modprobe cifs” on SP1 and SP2)?

Regards,
Jens

Hi Jens,

SP1: no result for “modprobe cifs”
SP2: -"-

SP1: modprobe -l | grep cifs ==> /lib/modules/2.6.32.59-0.7-default/kernel/fs/cifs/cifs.ko
SP2: modprobe -l | grep cifs ==> /lib/modules/3.0.80-0.7-default/kernel/fs/cifs/cifs.ko

SP1 & SP2:
installed: cifs-mount | Version 3.4.3-1.42.1

Hi netzpks,

“modprobe cifs”

my fault & my apology - make that “modinfo cifs”

Sorry,
Jens

Hi netzpks,

my apologies for the delay, it took me a while to get access to the proper systems. I now was able to test it… and it works for me both for SP1 and SP2.

What OS / server software is the server running, the one your SLES server connects to? Unfortunately, I cannot test against MS Windows, I have only Linux servers around…

Jens

Hi Jens!

Thank you for your efforts!
SLES connects to MS Windows.

Our Developer has adapted the python program. Now: “mount //server/share” and from there it is possible to change to the wanted folders.

Many thanks
