Before Creating a Serviceguard NFS Package
Before creating a Serviceguard NFS package, perform the following
tasks:
1. Set up your Serviceguard cluster according to the instructions in the
Managing Serviceguard manual.
2. On the primary node and all adoptive nodes for the NFS package, set
the NFS_SERVER variable to 1 in the /etc/rc.config.d/nfsconf
file.
NFS_SERVER=1
Do not configure the exported directories in the /etc/exports file.
When an NFS server boots up, it attempts to export all file systems
in its /etc/exports file. If those file systems are not currently
present on the NFS server node, the node cannot boot properly. This
happens if the server is an adoptive node for a file system, and the
file system is available on the server only after failover of the
primary node.
3. If your NFS servers must serve PC clients, set the PCNFS_SERVER
variable to 1 in the /etc/rc.config.d/nfsconf file on the primary
node and each adoptive node.
PCNFS_SERVER=1
If you run the NFS monitor script, setting the PCNFS_SERVER
variable to 1 will cause the monitor script to monitor the pcnfsd
daemon. Then, if the pcnfsd daemon fails, your NFS package will
fail over to an adoptive node. If you do not want to monitor pcnfsd,
do not run the NFS monitor script, or set the PCNFS_SERVER variable
to 0 and run pcnfsd manually from the command line.
4. If your NFS servers will also be NFS clients, set the START_MOUNTD
variable to 1 in the /etc/rc.config.d/nfsconf file on the primary
node and each adoptive node.
START_MOUNTD=1
If you configure rpc.mountd in the /etc/inetd.conf file, set the
START_MOUNTD variable to 0. If the START_MOUNTD variable is set to 0,
the NFS monitor script will not monitor the rpc.mountd process. If
