Configuration Requirements for Sharing a Highly Available Local File System Directory to a Zone Cluster

The directory of a highly available local file system managed by a global cluster resource can be shared to a zone cluster. To share a highly available local file system directory, the configuration must meet the following requirements:

  • Create an HAStoragePlus resource in a failover resource group in a global cluster with the file system where the directory to be shared belongs.

  • The directory of the highly available local file system that you want to share must be configured to a zone cluster as an lofs file system.

  • Create an HAStoragePlus resource in a failover resource group in a zone cluster with the lofs file system.

  • The zone cluster resource must have an offline restart dependency on the global cluster resource.

  • The zone cluster resource's resource group must have a strong positive affinity or strong positive affinity with failover delegation on the global cluster resource's resource group.


Note -  The applications sharing a highly available local file system will experience an availability impact due to colocation of the applications. An application failure on a node and its intent to fail over might have a cascading effect on other applications and the applications would be forced to fail over to another node. Mitigate the problem by reducing the number of applications that are sharing the file system. If the file system that is being shared is UFS, you can choose to configure the cluster file system to a zone cluster. See How to Set Up an HAStoragePlus Resource for Cluster File Systems Using a UFS File System.
