Is ZFS supported in a clustered environment?
Solaris Cluster 3.2 supports a local ZFS file system as highly available (HA) in the Solaris 10 11/06 release. This support allows for live failover between systems, with automatic import of pools between systems. If you use Solaris Cluster 3.2 to configure a local ZFS file system as highly available, review the following caution: Do not add a configured quorum device to a ZFS storage pool. When a configured quorum device is added to a storage pool, the disk is relabeled and the quorum configuration information is lost. This means the disk no longer provides a quorum vote to the cluster. After a disk is added to a storage pool, you can configure that disk as a quorum device. Or, you can unconfigure the disk, add it to the storage pool, then reconfigure the disk as a quorum device. Solaris Cluster 3.2 is not supported on the OpenSolaris or Nevada releases.
