Sun Cluster HA for NFS Restrictions

Note the following restrictions related to Sun Cluster HA for NFS.

• Do not run, on any Sun Cluster node, any applications that access the Sun Cluster HA for NFS file system locally. For example, on Sun Cluster systems, users should not locally access any Sun Cluster file systems that are NFS exported. This is because local locking interferes with the ability to kill and restart lockd(1M). Between the kill and the restart, a blocked local process is granted the lock, which prevents reclamation of the lock by the client machine.

• Sun Cluster does not support cross-mounting of Sun Cluster HA for NFS resources.

• Sun Cluster HA for NFS requires that all NFS client mounts be "hard" mounts.

• For Sun Cluster HA for NFS, do not use host name aliases for the logical hosts. NFS clients mounting HA file systems using host name aliases for the logical hosts might experience statd lock recovery problems.

• Sun Cluster does not support Secure NFS or the use of Kerberos with NFS. In particular, the secure and kerberos options to share_nfs(1M) are not supported.
