Registering and Configuring HA for Samba

This section contains the procedures you need to configure HA for Samba.

Some procedures within this section require you to use certain Oracle Solaris Cluster commands. Refer to the relevant Oracle Solaris Cluster command man page for more information about these command and their parameters.

How to Register and Configure HA for Samba

Determine if a single or multiple Samba instances will be deployed.

Refer to Restriction for multiple Samba instances that require winbind to determine how to deploy a single or multiple Samba instances with or without winbind.

Once you have determined how Samba will be deployed, you can chose one or more of the steps below.

1. Create a failover resource group for Samba.

   Use How to Register and Configure HA for Samba in a failover resource group for Example 1-3 and Example 1-4.

2. Create a scalable resource group for winbind.

   Use How to Register and Configure HA for Samba in a failover resource group with winbind in a scalable resource group for Example 1-5.

3. Create a failover resource group for an HA container for Samba.

   Use How to Register and Configure HA for Samba in an HA Container for Example 1-6.

How to Register and Configure HA for Samba in a failover resource group

This procedure assumes that you installed the data service packages during your initial Oracle Solaris Cluster installation.

If you did not install the HA for Samba packages as part of your initial Oracle Solaris Cluster installation, go to How to Install the HA for Samba Packages.

1. On a cluster member, become superuser or assume a role that provides solaris.cluster.modify RBAC authorization.
2. Register the following resource types.

   # clresourcetype register SUNW.HAStoragePlus
   # clresourcetype register SUNW.gds

3. Create a failover resource group for Samba.

   ---

   Note - Refer to Restriction for multiple Samba instances that require winbind for more information on the nodelist entry.

   ---

   # clresourcegroup create -n nodelist samba-resource-group

4. Create a resource for the Samba Logical Hostname.

   # clreslogicalhostname create -g samba-resource-group \
   > -h samba-logical-hostname \
   > samba-logical-hostname-resource

5. Create a resource for the Samba Disk Storage.
   1. If a ZFS highly available local file system is being used

      # clresource create -g samba-resource-group  \
      > -t SUNW.HAStoragePlus  \
      > -p Zpools=samba-zspool \
      > samba-hastorage-resource

   2. If a cluster file system or any other non-ZFS highly available local file system is being used

      # clresource create -g samba-resource-group  \
      > -t SUNW.HAStoragePlus  \
      > -p FilesystemMountPoints=samba-filesystem-mountpoint \
      > samba-hastorage-resource

6. Bring online the failover resource group for Samba that now includes the HA Storage and Logical Hostname resources.

   # clresourcegroup online -M samba-resource-group

7. If winbind is required, create and register a winbind resource.

   If Samba was dynamically linked and is being used as an Active Directory Server member you must configure the LDPATH variable to point to the Samba lib directory.

   Edit the samba_config file and follow the comments within that file. Ensure that SERVICES="winbindd" is specified. After you have edited samba_config, you must register the resource.

   # cd /opt/SUNWscsmb/util
   # vi samba_config
   # ./samba_register

   The following deployment example has been taken from Appendix B, Deployment Example: Installing Samba from http://www.samba.org.

   Vigor5# cat > /var/tmp/winbind_config <<-EOF #+++ Resource Specific Parameters +++ RS=winbind RG=samba-rg RS_LH=samba-lh RS_HAS=sambaZFS-has SERVICES="winbindd" #+++ Common Parameters +++ BINDIR=/opt/samba/bin SBINDIR=/opt/samba/sbin CFGDIR=/local/samba/smb1 LDPATH=/opt/samba/lib FMUSER=homer #+++ SMBD & NMBD Specific Parameters (See Note 1) +++ SAMBA_LOGDIR= SAMBA_FMPASS= SAMBA_FMDOMAIN= #+++ WINBIND Specific Parameters (See Note 2) +++ WINBIND_DISCACHE=FALSE WINBIND_SINGLEMODE=FALSE #+++ Zone Specific Parameters (See Note 3) +++ RS_ZONE= LHOST= PROJECT=default TIMEOUT=30 EOF

   Vigor5# /opt/SUNWscsmb/util/samba_register -f /var/tmp/winbind_config

8. If winbind is required enable the resource.

   # clresource enable winbind-resource

9. Create and register a Samba resource.

   If Samba was dynamically linked and is being used as an Active Directory Server member you must configure the LDPATH variable to point to the Samba lib directory.

   Edit the samba_config file and follow the comments within that file. Ensure that SERVICES="smbd" or SERVICES="smbd,nmbd" is specified. After you have edited samba_config, you must register the resource.

   # cd /opt/SUNWscsmb/util
   # vi samba_config
   # ./samba_register

   The following deployment example has been taken from Appendix B, Deployment Example: Installing Samba from http://www.samba.org.

   Vigor5# cat > /var/tmp/samba_config <<-EOF #+++ Resource Specific Parameters +++ RS=samba RG=samba-rg RS_LH=samba-lh RS_HAS=sambaZFS-has SERVICES="smbd" #+++ Common Parameters +++ BINDIR=/opt/samba/bin SBINDIR=/opt/samba/sbin CFGDIR=/local/samba/smb1 LDPATH=/opt/samba/lib FMUSER=homer #+++ SMBD & NMBD Specific Parameters (See Note 1) +++ SAMBA_LOGDIR=/local/samba/smb1/logs SAMBA_FMPASS=smb4#ads SAMBA_FMDOMAIN= #+++ WINBIND Specific Parameters (See Note 2) +++ WINBIND_DISCACHE= WINBIND_SINGLEMODE= #+++ Zone Specific Parameters (See Note 3) +++ RS_ZONE= LHOST= PROJECT=default TIMEOUT=30 EOF

   Vigor5# /opt/SUNWscsmb/util/samba_register -f /var/tmp/samba_config

10. If winbind is used, ensure Samba is dependent on winbind.

    # clresource set -p Resource_dependencies=winbind-resource{local_node} samba-resource

11. Enable the Samba resource.

    # clresource enable samba-resource

How to Register and Configure HA for Samba in a failover resource group with winbind in a scalable resource group

This procedure assumes that you installed the data service packages during your initial Oracle Solaris Cluster installation.

If you did not install the HA for Samba packages as part of your initial Oracle Solaris Cluster installation, go to How to Install the HA for Samba Packages.

1. On a cluster member, become superuser or assume a role that provides solaris.cluster.modify RBAC authorization.
2. Register the following resource types.

   # clresourcetype register SUNW.HAStoragePlus
   # clresourcetype register SUNW.gds

3. Create a failover resource group for the winbind shared network address.

   ---

   Note - Refer to Restriction for multiple Samba instances that require winbind for more information on the nodelist entry.

   ---

   # clresourcegroup create -n nodelist winbind-failover-resource-group

4. Create a resource for the winbind Logical Hostname.

   # clressharedaddress create -g winbind-failover-resource-group \
   > -h winbind-logical-hostname \
   > winbind-logical-hostname-resource

5. Create a scalable resource group for the scalable winbind resource.

   ---

   Note - Refer to Restriction for multiple Samba instances that require winbind for more information on the nodelist entry.

   ---

   # clresourcegroup create -n nodelist -S \
   > -p Maximum_primaries=maximum-number-active-primaries \
   > -p Desired_primaries=desired-number-active-primaries \
   > winbind-scalable-resource-group

6. Create a resource for the winbind Disk Storage.
