Configuring an HAStoragePlus Resource for Cluster File Systems

When an HAStoragePlus resource is configured for cluster file systems and brought online, it ensures that these file systems are available. The cluster file system is supported on a root ZFS file system and a nonroot UNIX File System (UFS). The instructions in this section apply to HAStoragePlus resources with UFS. Use HAStoragePlus with local file systems if the data service is I/O intensive. See How to Change the Cluster File System to Local File System in an HAStoragePlus Resource for information about how to change the file system of an HAStoragePlus resource.

The cluster file systems can be configured for zone clusters in the HAStoragePlus resources using the loopback mount mechanism. The SUNW.HAStoragePlus resource type makes the cluster file system available to a zone cluster by mounting the file system in the global cluster. The resource type then performs a loopback mount on the zone cluster nodes where the resource group is online.

The cluster file systems configured in the HAStoragePlus resource type for zone clusters should be authorized for use in zone clusters using the clzonecluster command. For more information, see the clzonecluster(1CL) man page and How to Add a Cluster File System to a Zone Cluster in Oracle Solaris Cluster Software Installation Guide.

Sample Entries in /etc/vfstab for Cluster File Systems

The following examples show entries in the /etc/vfstab file for global devices that are to be used for cluster file systems.

This example shows entries in the /etc/vfstab file for a global device that uses Solaris Volume Manager.

How to Set Up the HAStoragePlus Resource for Cluster File Systems

1. On any node in the cluster, become superuser or assume a role that provides solaris.cluster.modify RBAC authorization.
2. Create a failover or scalable resource group as desired.

   Perform the following step to create a failover group.

   # clresourcegroup create resource-group

   Perform the following step to create a scalable group.

   # clresourcegroup create -S [-p Maximum_primaries=m] [-p Desired_primaries=n] \ [-n node-zone-list] resource-group

3. Register the HAStoragePlus resource type.

   # clresourcetype register SUNW.HAStoragePlus

4. Create the HAStoragePlus resource and define the filesystem mount points.

   # clresource create -g resource-group -t SUNW.HAStoragePlus \ -p FileSystemMountPoints="mount-point-list" hasp-resource

   The resource is created in the enabled state.

5. Add the data service resources to resource-group, and set their dependency to hasp-resource.

   # clresource set -p Resource_dependencies_offline_restart= \ hasp-resource application-resource

6. Bring online and in a managed state the resource group that contains the HAStoragePlus resource.

   # clresourcegroup online -M resource-group

Example 2-31 Setting up the HAStoragePlus Resource Type with a Cluster File System in a Global Cluster

This example shows how to configure the HAStoragePlus resource with a cluster file system /global/ufs in a global cluster for a failover resource group.

phys-schost-1# vi /etc/vfstab
#device         device          mount           FS      fsck    mount   mount
#to mount       to fsck         point           type    pass    at boot options
#
/dev/md/apachedg/dsk/d0 /dev/md/apachedg/rdsk/d0 /global/ufs ufs 2 yes global, logging
# clresourcegroup create hasp-rg
# clresourcetype register SUNW.HAStoragePlus
# clresource create -g hasp-rg -t SUNW.HAStoragePlus -p \
FileSystemMountPoints=/global/ufs hasp-rs
# clresourcegroup online -M hasp-rg

Example 2-32 Setting up the HAStoragePlus Resource Type with a Cluster File System in a Zone Cluster

This example shows how to configure the HAStoragePlus resource with a cluster file system /global/ufs in a zone cluster for a scalable resource group. The cluster file system is available for the zone cluster nodes on the mount point /zone/ufs. This example configuration makes the global file system /global/ufs mounted in a global cluster and later loopback mounted on two zone-cluster nodes where the resource group is online.

phys-schost-1# vi /etc/vfstab
#device         device          mount           FS      fsck    mount   mount
#to mount       to fsck         point           type    pass    at boot options
#
/dev/md/apachedg/dsk/d0 /dev/md/apachedg/rdsk/d0 /global/ufs ufs 2 yes global, logging
# clzonecluster configure sczone
clzc:sczone> add fs
clzc:sczone:fs> set dir=/zone/ufs
clzc:sczone:fs> set special=/global/ufs
clzc:sczone:fs> set type=lofs
clzc:sczone:fs> end
clzc:sczone:fs> exit
# clresourcegroup create -Z sczone -p desired_primaries=2 -p maximum_primaries=2 hasp-rg
# clresourcetype register -Z sczone SUNW.HAStoragePlus
# clresource create -Z sczone -g hasp-rg -t SUNW.HAStoragePlus -p
FileSystemMountPoints=/zone/ufs hasp-rs
# clresourcegroup online -Z sczone -M hasp-rg

How to Delete an HAStoragePlus Resource Type for Cluster File Systems

• Disable and delete the HAStoragePlus resource configured for cluster file systems.

  # clresource delete -F -g resource-group -t SUNW.HAStoragePlus resource
