mount error 5 = Input/output error


I have been getting familar with a demo NetApp 8.2.1 ClusterMode in our lab.  I was trying to do some SPEC testing over CIFS.  So I recently setup CIFS on one of the SVMs.  It seems similar for the most part as a CIFS server on 7-mode ONTAP.  However, from my Redhat 5.8 VM, I can't seem to mount the CIFS share I created.


I get this message on the client:


mount error 5 = Input/output error


the complete output:


[root@llsfs01 /]# mount.cifs // /mnt2 --verbose -ouser=spec,password=spec123

mount.cifs kernel mount options: unc=//\cifstest,ip=,ver=1,user=spec,pass=********
mount error 5 = Input/output error
Refer to the mount.cifs(8) manual page ( mount.cifs)


my system works fine doing a mount of a CIFS on 8.1.4P1 7-mode in the lab:


[root@llsfs01 /]# mount.cifs //llnsa03/spectest /mnt2 --verbose -ouser=spec,password=spec123

mount.cifs kernel mount options: unc=//llnsa03\spectest,ip=,ver=1,user=spec,pass=********
[root@llsfs01 /]# mount


//llnsa03/spectest on /mnt2 type cifs (rw,mand)
[root@llsfs01 /]#


Any ideas what this error means?
