mount.cifs yields garbled directory listing where smbclient works

[ScottPurcell]

Binary package hint: samba

This mount command in Ubuntu does not work -- the directory listing is indecipherable:

scott@U904-209NVD1-95031:~$ sudo mount.cifs //pc1n7i01d03.us.dell.com/DTTUATNAS2/training /tmp/mnttest/ --verbose -o credentials=/etc/.cred.txt

mount.cifs kernel mount options: unc=//pc1n7i01d03.us.dell.com\DTTUATNAS2,user=scott_purcell,ver=1,credentials=/etc/.cred.txt,prefixpath=training,ip=10.30.25.221,pass=********

The same command in RHEL 5 works -- the files and directories are viewable:

[root@RH5-3G4DKB1-SLP ~]# mount.cifs //pc1n7i01d03.us.dell.com/DTTUATNAS2/training /tmp/mnttest/ --verbose -o credentials=/etc/.cred.txt

mount.cifs kernel mount options: unc=//pc1n7i01d03.us.dell.com\DTTUATNAS2,ip=10.30.25.221,user=scott_purcell,ver=1,credentials=/etc/.cred.txt,prefixpath=training,pass=********

smbclient in Ubuntu works fine -- the files and directories are browsable:

scott@U904-209NVD1-95031:~$ sudo smbclient //pc1n7i01d03.us.dell.com/DTTUATNAS2/ -W americas -U scott_purcell -D training

Please let me know what other information I can provide.

Works in smbclient, so looks like a kernel (CIFS) issue rather than a samba one.
Are those shares on the NAS DFS shares ?

[ScottPurcell (scott-texastwister)]

Not sure what you mean by NAS DFS. I believe it is on an EMC NAS box of some sort.

Confirmed that it works from a RHEL 5.4 box on an older kernel version, details in the newly attached file.

[Thierry Carrez (ttx)]

DFS are a special type of shares, used to aggregate directories coming from different locations into a single "share".
Marking as affecting "linux" (kernel) since smbclient is working fine. Getting the model of that EMS NAS box of some sort could probably help in debugging the issue.

[ScottPurcell (scott-texastwister)]

Resolved by the use of the "noserverino" mount option.
