How to Register and Configure Sun Cluster HA for Samba as a Failover Service with Winbind as a Scalable Service

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

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

Steps

1. Become superuser on one of the nodes in the cluster that will host Samba.

2. Register the SUNW.gds resource type.

   # scrgadm -a -t SUNW.gds

3. Register the SUNW.HAStoragePlus resource type.

   # scrgadm -a -t SUNW.HAStoragePlus

4. Create a failover resource group for the shared network address.

   # scrgadm -a -g Winbind-failover-resource-group

5. Create a resource for the Winbind Logical Hostname.

   # scrgadm -a -S -j Winbind-lh-resource \ -g Winbind-failover-resource-group \ -l Winbind-logical-hostname

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

   # scrgadm -a -g Winbind-scalable-resource-group \ -y Maximum_primaries=<number of nodes with Sun Cluster> \ -y Desired_primaries=<number of nodes with Sun Cluster> \ -y RG_dependencies=Winbind-failover-resource-group

7. Create a resource for the Winbind Disk Storage.

   # scrgadm -a -j Winbind-has-resource \ -g Winbind-scalable-resource-group \ -t SUNW.HAStoragePlus \ -x FilesystemMountPoints=Winbind-instance-mount-point \ -x AffinityOn=FALSE

8. Enable the failover and scalable resource group that now includes the Winbind Disk Storage and Logical Hostname resources.

   # scswitch -Z -g Winbind-failover-resource-group # scswitch -Z -g Winbind-scalable-resource-group

9. Create and register Samba as a failover data service.

   Follow Steps 4, 5, 6, 7, 10, and 11 in How to Register and Configure Sun Cluster HA for Samba as a Failover Service to create a failover Samba service. You then complete this last step to ensure that the Failover Samba Resource Group is start-dependent on the Scalable Winbind Resource Group.

   # scrgadm -c -g Samba-failover-resource-group \ -y RG_dependencies=Winbind-sclable-resource-group

10. Create and register winbind as a scalable data service.

    # cd /opt/SUNWscsmb/winbind/util

    Edit the winbind_config file and follow the comments within that file:.

    # These parameters can be customized in (key=value) form # # RS - name of the resource for the application # RG - name of the resource group containing RS # WB_BIN - name of the Winbind bin directory # WB_SBIN - name of the Winbind sbin directory. Used in Samba 3. # WB_INST - name of the Winbind configuration directory # NTUSER - name of the NT fault monitor user #WB_LIB_PATH- name of library paths to LD_LIBRARY_PATH #WB_DISCACHE - Should winbind cache be disabled. Used in Samba 3. #WB_SINGLEMODE - Should winbind run in single mode. Used in Samba 3. # LH - name of the LogicalHostname SC resource # HAS_RS - name of the Winbind HAStoragePlus SC resource

    The following is an example for a Winbind instance with Samba installed from http://www.samba.org.

    RS=wb-res RG=wb-scalable-rg WB_BIN=/global/samba/bin WB_INST=/global/samba/winbind NTUSER=samba WB_LIB_PATH=/usr/lib:/usr/local/lib WB_DISCACHE=FALSE WB_SINGLEMODE=FALSE LH=wmb-lh-res HAS_RS=wb-has-res

    After editing winbind_config, you must register the resource.

    # ./winbind_register

11. Enable the Winbind resource.

    # scstat # scswitch -e -j Winbind-resource
