POSIX error six means "no such device" (the share name may be misspelled)

Use smbclient (e.g. "smbclient -L //fs8") to see the list of shares.

Linux errors are defined in include/asm-generic/errno-base.h and errno.h
The cifs file system is limited in what it can return due to the
relatively small
number of errors defined in the Linux errno files.   Additional

More detailed information on what is causing this can be gotten from
the dmesg log:
1) "dmesg -c"  (clear the error log)
2) "echo 7 > /proc/fs/cifs/cifsFYI"  (enabling cifs
informational/debug messages)
3) try the mount and examine the dmesg output ("dmesg")

In addition a quick wireshark trace can often show the problem. See
   http://wiki.samba.org/index.php/Capture_Packets
for details on how to do this.
