How to Add a QFS Shared File System to a Zone Cluster

Perform this procedure to add a Sun QFS shared file system for use by a zone cluster.

At this time, QFS shared file systems are only supported for use in clusters that are configured with Oracle Real Application Clusters (RAC). On clusters that are not configured with Oracle RAC, you can use a single-machine QFS file system that is configured as a highly available local file system.

1. Become superuser on a voting node of the global cluster that hosts the zone cluster.

   Note –

   Perform all steps of this procedure from a voting node of the global cluster.

2. On the global cluster, configure the QFS shared file system that you want to use in the zone cluster.

   Follow procedures for shared file systems in Configuring Sun QFS File Systems With Sun Cluster.

3. On each node of the global cluster that hosts a zone-cluster node, add an entry to the /etc/vfstab file for the file system that you want to mount on the zone cluster.

   phys-schost# vi /etc/vfstab

4. Add the file system to the zone cluster configuration.

   phys-schost# clzonecluster configure zoneclustername clzc:zoneclustername> add fs clzc:zoneclustername:fs> set dir=mountpoint clzc:zoneclustername:fs> set special=QFSfilesystemname clzc:zoneclustername:fs> set type=samfs clzc:zoneclustername:fs> end clzc:zoneclustername> verify clzc:zoneclustername> commit clzc:zoneclustername> exit

5. Verify the addition of the file system.

   phys-schost# clzonecluster show -v zoneclustername

Example 7–6 Adding a QFS Shared File System to a Zone Cluster

The following example shows the QFS shared file system Data-cz1 added to the zone cluster sczone. From the global cluster, the mount point of the file system is /zones/sczone/root/db_qfs/Data1, where /zones/sczone/root/ is the zone's root path. From the zone-cluster node, the mount point of the file system is /db_qfs/Data1.

phys-schost-1# vi /etc/vfstab
#device     device    mount   FS      fsck    mount     mount
#to mount   to fsck   point   type    pass    at boot   options
#          
Data-cz1    -    /zones/sczone/root/db_qfs/Data1 samfs - no shared,notrace

phys-schost-1# clzonecluster configure sczone
clzc:sczone> add fs
clzc:sczone:fs> set dir=/db_qfs/Data1
clzc:sczone:fs> set special=Data-cz1
clzc:sczone:fs> set type=samfs
clzc:sczone:fs> end
clzc:sczone> verify
clzc:sczone> commit
clzc:sczone> exit

phys-schost-1# clzonecluster show -v sczone
