HP CIFS Client A.02.02.03 Administrator's Guide

• Basic Kerberos functionality If you suspect that basic functionality of your Kerberos infrastructure
is not working properly, repeat the verification checks in step 2.
• If you wish to set authenticationMethod for specific servers to a value different from the
global setting in the default Server section of the configuration file, you can create
server-specific options in the servers section. The servers section of the configuration file
is discussed near the end of Chapter 7, and the configuration file itself contains a sample
servers entry.
Troubleshooting cifsmount or mount in the HP CIFS Client
This section includes information about problems that you may encounter when using the
cifsmount or mount command to mount a share on a CIFS server and actions you may take to
correct the problems.
How to Do if the HP CIFS Client DLKM is Unused
You may encounter the following error messages when running the cifsmount or mount command
to mount the CIFS filesystem:
$ cifsmount -U <user> -P <password> //<server>/<share> /<mount-point>
ERROR: UNIX: No such device
or
$ mount -F cifs <server>:/<share> /<mount-point>
ERROR mount: cifs : Invalid argument
usage: mount [-l][-v|-p]
mount [-F FStype][-eQ] -a
mount [-F FStype][-eQrV][-o specific_options]
{ special | directory }
mount [-F FStype][-eQrV][-o specific_options]
special directory
To resolve the above errors, if you ensure that all the command-line arguments are correct and the
CIFS server is up.then use the following command to check the CIFS Client Dynamically Loadable
Kernel Module (DLKM) state:
$ kcmodule cifs
If the CIFS Client DLKM state is unused, the following output message is displayed:
Module State Cause Notes
cifs unused auto-loadable,unloadable
After you verify that the CIFS Client DLKM state is unused, you can use the following command
to change the CIFS Client DLKM state to auto, so the CIFS Client DLKM can be loaded. The
command and output message display are shown as follows:
$ kcmodule cifs=auto
* The sutomatic 'backup' configuration has been updated.
* The request changes have been applied to the currently
* running system.
Module State Cause Notes
cifs (before) unused auto-loadable,unloadable
(now) auto explicit
The auto state will enable the CIFS Client DLKM to be dynamically loaded when the first
cifsmount or mount command over the CIFS share is performed.
How to Do if You Encounter the Error Message: "Device Busy"
You may encounter the "device busy" error message when running the cifsmount or mount
command to mount the CIFS filesystem. To resolve this type of error, check to see whether the CIFS
filesystem mountpoint is tied to any process by running the fuser -fu mountpoint (see
