Conﬁguring HA HP CIFS

Overview of HA HP CIFS Server

Chapter 11 231

To do so, perform the following:

1. Following the instructions, conﬁgure the disk hardware for high

availability.

2. Use SAM or LVM commands to set up the volume groups, logical

volumes, and ﬁle systems needed for the data that must be available

to the primary and alternate cluster nodes when failover occurs.

HA HP CIFS Server Installation

1. Install HP CIFS Server using SD on all cluster nodes. If HP CIFS

Server is already installed and conﬁgured on either node, simply stop

it with the /opt/samba/bin/stopsmb command and skip to step 4.

2. On the ﬁrst node:

Run the script /opt/samba/bin/samba_setup to conﬁgure the

Samba server. Enter the server name and domain/workgroup name

for the HA HP CIFS Server.

3. On the secondary nodes:

Run the script /opt/samba/bin/samba_setup to conﬁgure the second

node. You will need to specify the same domain/workgroup name

speciﬁed on the ﬁrst node. Do not use the same server name.

4. For any UNIX users used to authenticate CIFS clients, check that

they have the same name, user ID number, primary group and

password on both of the nodes.

This is required for any users used to authenticate to either Samba

server in the Active-Active conﬁguration. This means that any user

name used on both Samba servers must have the same user ID,

primary group ID, and password on both cluster nodes. If this isn’t

the case, you cannot use Samba as an Active-Active server for this

MC/ServiceGuard cluster.

5. Check that the RUN_SAMBA parameter in the /etc/rc.conﬁg.d/samba

ﬁle is set to 0 on both nodes.
