To setup ${PRODUCT_NAME} you need to specify a directory to store various data
files in. For a ${PRODUCT_NAME} client or storage node the default directory
of ${NSR_HOME} is acceptable. However, for a ${PRODUCT_NAME} server, this
directory can become quite large and should reside on a big enough file system.

Below is a list of file systems which you might consider:

File system              Free space in KB
!
df -kl | grep "^/dev" | sort -k 4 -rn | awk '{printf("%-30s %10s\n",$6,$4)}'

# use existing NSR_HOME if one exists
[ -d /nsr ] && NSR_HOME=/nsr
[ -h /nsr ] && NSR_HOME=`ls -l /nsr | awk '{print $11}'`

while true; do
	nsrhome=`ckpath -Q -a -p "Enter a ${PRODUCT_NAME} data directory (default=${NSR_HOME})" -d ${NSR_HOME}`

	# check to see if directory is on a local file system
	dir=${nsrhome}
	while [ ! -d ${dir} ]; do
		dir=`dirname ${dir}`
	done
	if [ `df -n ${dir} | awk '{print $3}'` = "nfs" ]; then
		echo "ERROR: ${nsrhome} is not on a local file system"
		continue
	fi

	NSR_HOME=${nsrhome}
	break;
done
