Sun Cluster Data Service for Samba Guide for Solaris OS

Registering and Configuring Sun Cluster HA for Samba

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

How to Register and Configure Sun Cluster HA for Samba as a Failover 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.

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

Create a failover resource group.

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

Create a resource for the Samba Disk Storage.

# scrgadm -a -j Samba-has-resource  \
-g Samba-failover-resource-group   \
-t SUNW.HAStoragePlus  \
-x FilesystemMountPoints=Samba- instance-mount-points

Create a resource for the Samba Logical Hostname.

# scrgadm -a -L -j Samba-lh-resource  \
-g Samba-failover-resource-group  \
-l Samba-logical-hostname

Enable the failover resource group that now includes the Samba Disk Storage and Logical Hostname resources.
# scswitch -Z -g Samba-failover-resource-group

Create and register Winbind as a failover data service (if required).

# 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=smb-failover-rg
WB_BIN=/global/samba/bin
WB_INST=/global/samba/SAMBA1
NTUSER=samba
WB_LIB_PATH=/usr/lib:/usr/local/lib
WB_DISCACHE=FALSE
WB_SINGLEMODE=FALSE
LH=smb-lh-res
HAS_RS=wb-has-res

After editing winbind_config, you must register the resource.

# ./winbind_register

Enable the Winbind resource (if the previous step was done).
# scstat # scswitch -e -j Winbind-resource

Create and register Samba as a failover data service.

# cd /opt/SUNWscsmb/samba/util

Edit the samba_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
#   SMB_BIN - name of the Samba bin directory
#  SMB_SBIN - name of the Samba sbin directory
#              (If no sbin then specify the bin directory)
#  SMB_INST - name of the Samba configuration directory
#   SMB_LOG - name of the Samba log directory
#               for log.smbd and log.nmbd
#              (If not specified will default
#               to $SMB_INST/logs) 
#SMB_LIB_PATH - name of library paths to LD_LIBRARY_PATH
#    FMUSER - name of the Samba fault monitor user
#    FMPASS - name of the Samba fault monitor user password
#  FMDOMAIN - name of the NT-domain faultmonitor user is configured on.
#             ( This should be used if faultmonitor user is not configured
#               on the same NT-domain Samba is member to )
#        LH - name of the LogicalHostname SC resource
#    HAS_RS - name of the Samba HAStoragePlus SC resource

The following is an example for Samba instance SAMBA1 with Samba installed from http://www.samba.org.

RS=smb-res
RG=smb-failover-rg
SMB_BIN=/global/samba/bin
SMB_SBIN=/global/samba/sbin or /global/samba/bin
SMB_INST=/global/samba/SAMBA1
SMB_LOG=/global/samba/SAMBA1/logs
SMB_LIB_PATH=/usr/lib:/usr/local/lib
FMUSER=samba
FMPASS=samba
FMDOMAIN=
LH=smb-lh-res
HAS_RS=smb-has-res or 
HAS_RS=smb-has-res,wb-res if failover winbind is being used

The following is an example for Samba instance SMB1 with Samba installed from Solaris 9.

RS=smb-res
RG=smb-failover-rg
SMB_BIN=/usr/sfw/bin
SMB_SBIN=/usr/sfw/sbin
SMB_INST=/local/samba/SMB1
SMB_LOG=/local/samba/SMB1/logs
FMUSER=samba
FMPASS=samba
LH=smb-lh-res
HAS_RS=smb-has-res

After editing samba_config, you must register the resource.

# ./samba_register

Enable each Samba resource.

Repeat this step for each Samba instance, if multiple instances were created.
# scstat # scswitch -e -j Samba-resource

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.

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

Create a failover resource group for the shared network address.
# scrgadm -a -g Winbind-failover-resource-group

Create a resource for the Winbind Logical Hostname.

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

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

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

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

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

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

Enable the Winbind resource.

# scstat 
# scswitch -e -j Winbind-resource
