Cannot access Windows Share on Netapp from Xubuntu 14.04 using Samba

Question

since I used to mount samba share on Netapp with a command like :

mount -t cifs //netapp.dns.name/myshare /home/myhome/myshare --verbose -o credential=/home/myhome/.credential,sec=ntlm,iocharset=utf8,dir_mode=0777,file_mode=0666,nounix,noserverino

Last week, there was OK, but monday I got this error :

domain=MYDOMAIN
mount.cifs kernel mount options: ip=10.nnn.nnn.nnn,unc=\\netapp.dns.name\my.login,sec=ntlm,iocharset=utf8,dir_mode=0777,file_mode=0666,nounix,noserverino,user=olivier.savoye,,domain=MYDOMAIN,pass=********
mount error(5): Input/output error
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Here are syslog messages :

I don't see anything that could have an effect on my cifs mount except (perhaps) the libgcrypt11 package.

I don't try to remove it for an older because I am not sure it can help.

Could someone give me some advice ?

I tried all possible options (and no option sec=) without success — Olivier, Sep 10 '14 at 16:33

I have the same problem with a ONTAP share.

I think it is related to this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1372482

Using fuse with the kernel 3.13.0-36 works OK.

Using fuse or mount.cifs with kernel 3.13.0-35 works OK.

So it seems is a 3.13.0-36 kernel problem with cifs-utils.

I have tried kernel 3.13.0-37.44 from the Canonical Kernel Team http://www.ubuntuupdates.org/ppa/canonical_kernel_team?dist=trusty without luck. Same error.

As a workaround I have changed the default kernel to 3.13.0-35 with this guide: Set "older" kernel as default grub entry

I faced the same problem this week, with exaclty the same output message, as well as the one you found in syslog. I do not use a Netapp, but a simple Western Digital My Book World NAS.

In parallel I have a Synology NAS DS414 which I can mount his cifs shares without any problem.

I made some recent updates too. As part of them : the kernel; an upgrade from 3.13.0-35-generic to 3.13.0-36-generic.

I fallback my system with the 3.13.0-35-generic kernel, and everything worked fine again.

I still don't understand why I could mount Synology shares, and not my Western Digital ones. Except that my Western Digital used an old version of samba. Compatibility version ? Regression of the kernel ? I don't know !!!
