# This is a sample for defining parameters for HA-NFS over GPFS                #
# Copy this sample file to /var/mmfs/etc/nfsdefs and uncomment the lines that  #
# specify parameters                                                           #
################################################################################

# Specify the root of the filesystem used for storing shared state required
# for HA-NFS failover and failback. This is a system directory that SHOULD NOT
# exported for NFS
# This parameter is MANDATORY
# SHARED_ROOT=/gpfs/gpfsA

# Specify the IP addresses for the list of nodes belonging to the GPFS cluster
# The format of this file is as follows:
# GPFS_IP[:eth:mask] NFS_IP1 NFS_IP2 ...
# See nfs.nodes.sample for a sample of this file.
# This parameter is MANDATORY
# NODELIST=/var/mmfs/etc/nfs.nodes

# Specify the (virtual) DNS name used by clients to address the HA cluster. 
# For example, if the GPFS cluster includes the nodes with names "gpfs1", 
# "gpfs2", "gpfs3" and the virtual DNS name for the cluster is "gpfs", 
# the clients are allowed to NFS mount from "gpfs" instead of 
# individually from "gpfs1", etc.
# This parameter is OPTIONAL
# VIP=virtualname

# Specify the location of the log file for HA-NFS debug messages
# This parameter is OPTIONAL (default /var/mmfs/gen/mmfslog)
# If specified, LOGFILE will be rotated on every (re)start (or recovery) of GPFS
# LOGFILE=/tmp/ha-nfs.log

# Specify the mechanism for communicating between GPFS nodes. Appropriate
# configuration is required to ensure password-less access between the nodes.
# This parameter is OPTIONAL (default rsh/rcp/xinetd)
# GPFS_RSH=/usr/bin/ssh
# GPFS_RCP=/usr/bin/scp
# GPFS_RSHD=sshd

# Specify whether monitoring of various daemons/processes required for correct
# functioning of HA-NFS should be enabled.
# This parameter is OPTIONAL (default 1)
# MONITOR=0

# Specify whether extra messages should be logged for debugging.
# This parameter is OPTIONAL (default 0, levels 1-2 allowed)
# DEBUG=1

# SLES9 clients have a bug that prevents them from reclaiming NLM locks
# correctly on node failures. If clients mount NFS shares using hostnames
# (or IP addresses) OTHER THAN the virtual name (VIP above), enable the
# parameter below.
# This parameter is OPTIONAL (default 0)
# NOTIFYFIX=1

# Autostart GPFS on boot
# This parameter is OPTIONAL (default 0)
# AUTOSTART=1

# Reboot node on failure
# This parameter is OPTIONAL (default 0)
# REBOOT=1

# The following parameters are OPTIONAL and should only be changed if you know #
# what you are doing :)                                                        #

# Specify the number of NFS server kernel threads to run 
# This parameter is OPTIONAL (default is 32)
# NFSD_PROCS=32

# For HA-NFS to work correctly with GPFS cluster, the NLM daemons on the
# different nodes MUST be bound to different port numbers. Specify the "base"
# port number to be used to compute the NLM port number (Port no. is calculated
# as NLM_PORT + node number). Choose a range of ports that are not used on any
# node of the cluster.
# This parameter is OPTIONAL (default is 10000)
# NLM_PORT=10000

# For HA-NFS to work correctly with Automounter (AMD), the MOUNT daemons on the
# different nodes MUST be bound to the same port numbers.
# This parameter is OPTIONAL (no default)
# MOUNTD_PORT=""

# Specify the level of monitoring to be done on various subsystems required for
# HA-NFS.
# The following levels are defined:
# 0 	No monitoring to be done for this subsystem
# 1 	Monitor this subsystem and signal an alert when it is stopped
# 2 	Monitor this subsystem and restart it when it it stopped 
#	(This may not be applicable for all services)
# 3 	Monitor this subsystem and fail the node when it is stopped

# Specify the level for monitoring IP interfaces
# MONITOR_NETWORK=3
# Specify the level for monitoring portmap service
# MONITOR_PORTMAP=3
# Specify the level for monitoring nfsd service
# MONITOR_NFSD=3
# Specify the level for monitoring mountd service
# MONITOR_MOUNTD=3
# Specify the level for monitoring statd (NLM) service
# MONITOR_STATD=3
# Specify the level for monitoring rsh/ssh service
# MONITOR_SSHD=3

# Specify the frequency of at which subsystems are monitored in seconds (default 15)
# MONITOR_INTERVAL=15
