[opensuse] CIFS mounts in 42.3 with latest kernel
I am trying to troubleshoot a CIFS mount issue on Leap 42.3. It is mounting shares from a Windows server. All was working until a couple of days ago. Now, when I try to mount the shares, I get this in the log: [244622.138475] Status code returned 0xc0000001 NT_STATUS_UNSUCCESSFUL [244622.138501] CIFS VFS: Send error in SessSetup = -5 [244622.138749] CIFS VFS: cifs_mount failed w/return code = -5 The mysterious thing is that it started with the latest kernel update. I have a system running 4.4.87-25-default that works fine. On the systems with 4.4.92-31-default or newer, I now get these messages. It is not limited to one machine. The common thing seems to be that they have a newer kernel and are generally up to date (zypper dup). Is anyone else having problems? I would have expected some traffic here if that had been the case. If it was limited to one machine I would suspect that machine. If the older kernel machine had stopped working I would suspect the Windows server. In fact, all is suspect at this time. The error happens both via automount (systemd vai /etc/fstab) and a direct mount command. I have tried the suggestions in https://www.suse.com/support/kb/doc/?id=7017413, but it made no difference. For example: # mount --verbose -t cifs /server/data6 /media/mma-sql-1/data6 -o username=me,domain=here,sec=ntlm Password for me@//server/data6: ************ mount.cifs kernel mount options: ip=10.2.67.50,unc=\\server\data6,sec=ntlm,user=me,,domain=here,pass=******** mount error(5): Input/output error Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) The error in the log is as listed at the start of this message. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

it could be the SMB version. try to add "vers=1.0" to the mount options. -- Best Regards | Freundliche Grüße | Cordialement | Cordiali Saluti | Atenciosamente | Saludos Cordiales DI Rainer Klier Research & Development, DevOps _________________________________________________________ Namirial GmbH

I have been trying various versions, but it makes no difference. I turned on some debugging, and now there is a buffer in the system log when this happens. Part of it is; [261480.510081] 0000 4e00 ...N [261480.510096] 53ff 424d 0072 0000 0000 c001 0000 0000 .SMBr........... [261480.510104] 0000 0000 0000 0000 0000 114c 0000 0001 ..........L.....

I have tried them all, and the problem persists. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I missed a detail in your message: why is your CIFS reporting 2.10 while mine is reporting 2.08? I am running the current Leap 42.3 kernel. What are you running? kernel-default-4.4.87-25.1.x86_64 cifs-utils-6.5-5.1.x86_64 Maybe I need to have 2.10 running on my Linux system? -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

no, I am running Tw. I just remembered having to add the vers info and thought it might help. fwiw: I know little of cifs and used google to set up what I have. and it seems that few examples use the same parameters for seemingly common situations. I must have experimeted with > 20 different sets for fstab before getting it to work. then three times updates killed it and it was only solved by additional parameters, the last being the vers info. gud luk, -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Registered Linux User #207535 @ http://linuxcounter.net Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet freenode -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Does "smbclient //server/data6 -I 10.2.67.50" give you a shell with access to the share? If not, you can specify the debug level up to 10 with "-d ". BTW, wireshark speaks SMB.

The ntlm defaults have changed, I forget which version, but try: -o sec=ntlmssp instead of sec=ntlm -- David C. Rankin, J.D.,P.E. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
