Limitations of ServiceGuard NFS

File locks are not maintained when an NFS server package moves to an adoptive node. Any applications that use file locking must reclaim their locks after an NFS server package fails over. An application that loses its file lock as a result of an NFS package failover will not be notified. If the server is also an NFS client, any file locks it holds will be lost.

A system administrator may need to manually maintain or remove persistent file-lock states for the failed node. The previous file-lock states may remain available on the failed node.

This toolkit supports NFS servers that have the Linux operating system and ServiceGuard A.11.14.02 for Linux installed with RedHat 7.3 RedHat Advanced Server 2.1, or Linux Enterprise Server 8 powered United Linux 1.0 (subsequently referred to as SLES 8/UL 1.0). It does not guarantee that other configurations will work appropriately with the NFS Toolkit on Linux.
