How to Add a UFS Cluster File System to a Zone Cluster (CLI)

Perform this procedure to add a UFS cluster file system for use by a zone cluster.

Note:

Alternatively, you can use the clsetup utility to perform this task. See How to Add a Cluster File System to a Zone Cluster (clsetup).

1. Assume the root role on a voting node of the global cluster that hosts the zone cluster.

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

2. On the global cluster, configure the cluster file system that you want to use in the zone 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
   …
   /dev/global/dsk/d12s0 /dev/global/rdsk/d12s0/ /global/fs ufs 2 no global, logging

4. Configure the cluster file system as a loopback file system for the zone cluster.

   phys-schost# clzonecluster configure zone-cluster-name
   clzc:zone-cluster-name> add fs
   clzc:zone-cluster-name:fs> set dir=zone-cluster-lofs-mountpoint
   clzc:zone-cluster-name:fs> set special=global-cluster-mount-point
   clzc:zone-cluster-name:fs> set type=lofs
   clzc:zone-cluster-name:fs> end
   clzc:zone-cluster-name> verify
   clzc:zone-cluster-name> commit
   clzc:zone-cluster-name> exit

   dir=zone-cluster-lofs-mount-point

   Specifies the file system mount point for LOFS to make the cluster file system available to the zone cluster.

   special=global-cluster-mount-point

   Specifies the file system mount point of the original cluster file system in the global cluster.

   For more information about creating loopback file systems, see the lofiadm(8) man page.

5. Verify the addition of the LOFS file system.

   phys-schost# clzonecluster show -v zone-cluster-name

Example 6-6 Adding a UFS Cluster File System to a Zone Cluster (CLI)

The following example shows how to add a cluster file system with mount point /global/apache to a zone cluster. The file system is available to a zone cluster using the loopback mount mechanism at the mount point /zone/apache.

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/oracle/dsk/d1 /dev/md/oracle/rdsk/d1 /global/apache ufs 2 yes global, logging

phys-schost-1# clzonecluster configure zone-cluster-name
clzc:zone-cluster-name> add fs
clzc:zone-cluster-name:fs> set dir=/zone/apache
clzc:zone-cluster-name:fs> set special=/global/apache
clzc:zone-cluster-name:fs> set type=lofs
clzc:zone-cluster-name:fs> end
clzc:zone-cluster-name> verify
clzc:zone-cluster-name> commit
clzc:zone-cluster-name> exit

phys-schost-1# clzonecluster show -v sczone
…

Next Steps

Configure the cluster file system to be available in the zone cluster by using an HAStoragePlus resource. The HAStoragePlus resource manages the mounting of the file systems in the global cluster, and later performs a loopback mount on the zone-cluster nodes that currently host the applications that are configured to use the file system. For more information, see Configuring an HAStoragePlus Resource for Cluster File Systems in Planning and Administering Data Services for Oracle Solaris Cluster 4.4.
