Sun Cluster Data Service for Samba Guide for Solaris OS

Appendix A Deployment Example: Installing Samba packaged with Solaris 10

This appendix presents a complete example of how to install and configure the Samba application and data service in the global and non-global zone. It presents a simple node cluster configuration. If you need to install the application in any other configuration, refer to the general-purpose procedures presented elsewhere in this manual.

Target Cluster Configuration

This example uses a single-node cluster with the following node and zone names:

Vigor5: The physical node, which owns the file system.
Vigor5:whole: A whole root non-global zone named whole.
Vigor5:sparse: A sparse root non-global zone named sparse.

Software Configuration

This deployment example uses the following software products and versions:

Solaris 10 6/06 software for SPARC or x86 platforms
Sun Cluster 3.2 core software
Sun Cluster HA for Samba data service
Samba packaged with Solaris 10

This example assumes that you have already installed and established your cluster. It illustrates installation and configuration of the data service application only.

Assumptions

The instructions in this example were developed with the following assumptions:

Shell environment: All commands and the environment setup in this example are for the Korn shell environment. If you use a different shell, replace any Korn shell-specific information or instructions with the appropriate information for you preferred shell environment.
User login: Unless otherwise specified, perform all procedures as superuser or assume a role that provides solaris.cluster.admin, solaris.cluster.modify, and solaris.cluster.read RBAC authorization.

Installing and Configuring Samba packaged with Solaris 10

Note –

This deployment example is designed for a single-node cluster. It is provided simply as a concise guide to help you if you need to refer to an installation and configuration of Samba.

This deployment example is not meant to be a precise guide as there are several alternate ways to install and configure Samba.

If you need to install Samba in any other configuration, refer to the general purpose procedures elsewhere in this manual.

The instructions with this deployment example assumes that you are using the Samba software packaged with Solaris 10 and will configure Samba on a ZFS highly available local file system .

The cluster resource group will be configured to failover between the global zone and two non-global zones on a single node cluster.

The tasks you must perform to install and configure Samba in the global and non-global zones are as follows:

Example: Prepare the Cluster for Samba

Install and configure the cluster as instructed in Sun Cluster Software Installation Guide for Solaris OS.

Install the following cluster software components on node Vigor5.
- Sun Cluster core software
- Sun Cluster data service for Samba

Add the logical host name to /etc/hosts and /etc/inet/ipnodes

Vigor5# grep SMB1 /etc/hosts /etc/inet/ipnodes
/etc/hosts:192.168.1.132	SMB1#20
/etc/inet/ipnodes:192.168.1.132	SMB1#20

Install and configure a Zettabyte File System
1. Create a ZFS pool.
  
  Note –
  The following zpool definition represents a very basic configuration for deployment on a single-node cluster.
  
  You should not consider this example for use within a productive deployment, instead it is a very basic configuration for testing or development purposes only.
  Vigor5# zpool create -m /local HAZpool c1t1d0
2. Create a ZFS
  Vigor5# zfs create HAZpool/samba

Create the Samba Fault Monitor Userid in the Global Zone

Vigor5# groupadd -g 1000 samba
Vigor5# useradd -u 1000 -g 1000 -s /bin/false homer

Example: Configure the Non-Global Zones

In this task you will install two Solaris Containers on node Vigor5.

On local cluster storage create a directory for the non-global zones root path.
Vigor5# mkdir /zones

Create a temporary file for the whole root zone, for example /tmp/whole, and include the following entries:
Vigor5# cat > /tmp/whole <<-EOF create -b set zonepath=/zones/whole EOF

Create a temporary file for the sparse root zone, for example /tmp/sparse, and include the following entries:
Vigor5# cat > /tmp/sparse <<-EOF create set zonepath=/zones/sparse EOF

Configure the non-global zones, using the files you created.

Vigor5# zonecfg -z whole -f /tmp/whole
Vigor5# zonecfg -z sparse -f /tmp/sparse

Install the zones.

Open two windows and issue the following command in each window.
Vigor5# zoneadm -z whole install Vigor5# zoneadm -z sparse install

Boot the zones.

Vigor5# zoneadm -z whole boot
Vigor5# zoneadm -z sparse boot

Log in to the zones and complete the zone system identification.
Vigor5# zlogin -C whole Vigor5# zlogin -C sparse

Close the terminal windows and disconnect from the zone consoles.

After you have completed the zone system identification, disconnect from the two windows your previously opened.
Vigo5# ~.

Create local mount points for the HA-ZFS file system with in the zones.

Vigor5# zlogin whole mkdir /local
Vigor5# zlogin sparse mkdir /local

Create the Samba Fault Monitor Userid in the zones.

Vigor5# zlogin whole groupadd -g 1000 samba
Vigor5# zlogin sparse groupadd -g 1000 samba
Vigor5# zlogin whole useradd -u 1000 -g 1000 -s /bin/false homer
Vigor5# zlogin sparse useradd -u 1000 -g 1000 -s /bin/false homer

Example: Configure Cluster Resources for Samba

Vigor5# clresourcetype register SUNW.gds SUNW.HAStoragePlus

Create the Samba resource group.

Vigor5# clresourcegroup create -n Vigor5,Vigor5:whole,Vigor5:sparse samba-rg

Create the logical host.

Vigor5# clreslogicalhostname create -g samba-rg -h SMB1 samba-lh

Create the HAStoragePlus resource in the samba-rg resource group.

Vigor5# clresource create -g samba-rg -t SUNW.HAStoragePlus \
> -p Zpools=HAZpool sambaZFS-has

Enable the resource group.

Vigor5# clresourcegroup online -M samba-rg

Example: Create the Samba `smb.conf` Configuration File

Create the Samba Configuration Directory.

Vigor5# mkdir -p /local/samba/smb1
Vigor5# cd /local/samba/smb1
Vigor5# mkdir -p lib logs private shares var/locks

Create the Samba smb.conf Configuration File.

Vigor5# cat > /local/samba/smb1/lib/smb.conf <<-EOF
[global]
        workgroup = PDC
        bind interfaces only = yes
        interfaces = SMB1/255.255.255.0
        netbios name = SMB1
        security = user
        server string = Samba (%v) domain (%h)
        pid directory = /local/samba/smb1/var/locks
        log file = /local/samba/smb1/logs/log.%m
        smb passwd file = /local/samba/smb1/private/smbpasswd
        private dir = /local/samba/smb1/private
        lock dir = /local/samba/smb1/var/locks
        domain logons = yes
        domain master = yes
        preferred master = yes

[scmondir]
        comment = Monitor directory for Sun Cluster
        path = /tmp
        browseable = No
EOF

Test the Samba smb.conf Configuration File.

Vigor5# /usr/sfw/bin/testparm -s /local/samba/smb1/lib/smb.conf

Add the Samba Fault Monitor Userid.

Note –
You should specify samba as the password, otherwise you will need to change the SAMBA_FMPASS variable in Step 1 in Example: Enable the Samba Software to Run in the Cluster
Vigor5# /usr/sfw/bin/smbpasswd -c /local/samba/smb1/lib/smb.conf -a homer

Example: Verify Samba

Start Samba using the smbd program.

Vigor5# /usr/sfw/sbin/smbd -s /local/samba/smb1/lib/smb.conf -D

Connect to Samba using the smbclient program.

Vigor5# /usr/sfw/bin/smbclient -N -L SMB1 -s /local/samba/smb1/lib/smb.conf
Vigor5#
Vigor5# /usr/sfw/bin/smbclient '\\SMB1\scmondir' -U homer -c 'pwd;exit' \
> -s /local/samba/smb1/lib/smb.conf

Stop Samba.
Vigor5# pkill -TERM smbd

Example: Enable the Samba Software to Run in the Cluster

Create the Sun Cluster HA for Samba Configuration file.
