Serviceguard NFS Toolkit A.11.31.02 Release Notes (March 2008)

Limitations
The following lists the limitations of using Serviceguard NFS Toolkit A.11.31.02 with
Serviceguard A.11.18 and CFS:
• Lock coherency for multiple NFS servers is not supported. NFS file lock coherency
is not supported when multiple NFS servers are concurrently accessing a file. Lock
operations does not return an error, but lock coherency is not guaranteed. This
may cause data corruption or cause an application to hang.
• Cross mounting using the nfs_xmnt script is not supported, since CFS provides
file sharing functionality within the cluster.
• Secure NFS is not supported when using Serviceguard with CFS.
• The maximum number of NFS server nodes available is four.
• NFS Version 4 protocol is not supported.
