Cluster File System with ZFS - Introduction and Configuration
Oracle Solaris Cluster as of 4.3 release has support for:
- Cluster File System with UFS
- ZFS as a failover file system
For application deployments that require accessing the same file system across multiple nodes, ZFS as a failover file system will not be a suitable solution. ZFS is the preferred data storage management on Oracle Solaris 11 and has many advantages over UFS. With Oracle Solaris Cluster 4.4, now you can have both ZFS and global access to ZFS file systems.
Oracle Solaris Cluster 4.4 has added support for:
- Cluster File System with ZFS
With this new feature, you can now make ZFS file systems accessible from multiple nodes and run applications from the same file systems simultaneously on those nodes. It must be noted that zpool for globally mounted ZFS file systems does not actually mean a global ZFS pool, instead there is a Cluster File System layer that is present on top of ZFS that makes the file systems of the ZFS pool globally accessible.
