Limitations of ServiceGuard NFS
The following limitations apply to 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.
