7 Using CIFS

The X9000 Software CIFS server implementation allows you to create file shares for data stored
on the cluster. The CIFS server provides a true Windows experience for Windows clients. A user
accessing a file share on an X9000 system will see the same behavior as on a Windows server.

IMPORTANT:

Before configuring CIFS, select an authentication method (either Local Users or

Active Directory). See

“Configuring authentication for CIFS, FTP, and HTTP” (page 42)

for more

information.

IMPORTANT:

CIFS and X9000 Windows clients cannot be used together because of incompatible

AD user to UID mapping. You can use either CIFS or X9000 Windows clients, but not both at the
same time.

Configuring file serving nodes for CIFS

To enable file serving nodes to provide CIFS services, you will need to configure the resolv.conf
file. On each node, the /etc/resolv.conf file must include a DNS server that can resolve SRV
records for your domain. For example:

# cat /etc/resolv.conf

search mycompany.com
nameserver 192.168.100.132

To verify that a file serving node can resolve SRV records for your AD domain, run the Linux dig
command. (In the following example, the Active Directory domain name is mydomain.com.)

% dig SRV _ldap._tcp.mydomain.com

In the output, verify that the ANSWER SECTION contains a line with the name of a domain controller
in the Active Directory domain. Following is some sample output:

; <<>> DiG 9.3.4-P1 <<>> SRV _ldap._tcp.mydomain.com
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 56968
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 2

;; ANSWER SECTION:

;; ADDITIONAL SECTION:

;; WHEN: Tue Mar 16 09:56:02 2010
;; MSG SIZE rcvd: 113

For more information, see the Linux resolv.conf(5) man page.

Starting or stopping the CIFS service and viewing CIFS statistics

IMPORTANT:

You will need to start the CIFS service initially on the file serving nodes.

Subsequently, the service is started automatically when a node is rebooted.

Use the CIFS tab on the management console GUI to start, stop, or restart the CIFS service on a
particular node, or to view CIFS activity statistics for the node. Select Servers from the Navigator
and then select the appropriate node. Select CIFS in the lower Navigator to display the CIFS tab,
