Yes, there is. But before trying to administrate a HACMP-cluster you should really REALLY know what you are doing. This can end up in disaster pretty fast.

In the details of of the resource groups definition (the same SMIT panel where you also state the VGs which belong to it) you can also define NFS-mounts to be part of the RG. Note, that you will need some non-NFS file system for NFS-4 mounts. (Because, unlike NFS3, NFS4 is state-aware. Locked files stay locked.)

Notice also that for NFS4 to work you need different services started, not the same as for NFS3. You also need to configure the NFS-domain before, which i suggest to be the same as the DNS-domain of the system (as this is easier to manage).

I hope this helps.

MOUNTD(8)						    BSD System Manager's Manual 						 MOUNTD(8)

NAME
mountd -- service remote NFS mount requests SYNOPSIS
Obsolete. See nfsd(8). DESCRIPTION
The mountd daemon was formerly the server for NFS mount requests from NFS clients. This functionality has been moved into the NFS server daemon nfsd(8). Please refer to nfsd(8) for NFS server documenation. The following is a list of former mountd options that are now available as nfsd(8) options: mountd option nfsd option Description -n -N allow non-root mounts -r -R allow regular file mounts exportsfile -F exportsfile alternate exports file However, such configuration options are normally specified via nfs.conf(5). When the NFS server is started, it loads the export host addresses and options into the kernel using the nfssvc(2) system call. After chang- ing the list of exports (either directly or indirectly via a change in netgroup membership), the administrator should send a hangup signal to the nfsd daemon to get it to reload the export information: kill -s HUP `cat /var/run/nfsd.pid` For backwards compatibility, the following should also work: kill -s HUP `cat /var/run/mountd.pid` Any errors encountered while processing the export entries will be logged via syslog(3). FILES
/etc/exports the list of exported filesystems /var/run/mountd.pid the pid of the currently running mountd /var/run/mountdtab the current list of outstanding mounts served /var/run/mountdexptab information about exported file systems and directories (UUIDs, handles, ...) SEE ALSO
nfsd(8), exports(5), nfs.conf(5), nfsstat(1), portmap(8), showmount(8) HISTORY
The mountd utility first appeared in 4.4BSD. It's functionality was merged into nfsd(8) in Darwin 9. BSD
November 10, 2006 BSD
