A cleaner way of mounting the nfs shares than Josep provided is
something like what I have below. It looks for whether the nfs server
responds to a ping rather than the default route and will retry 3 times
with a 3 second timeout each time. It also checks all nfs mount points
listed in /etc/fstab which largely restores the functionality of that
file.
In any case this is a work around and it seems that fixing the original
bug would be preferable to continued effort in this direction.
cat /etc/fstab | sed 's/#.*//' | grep nfs | while read LINE
do
HOST=`echo "$LINE" | cut -f1 -d:`
DIR=`echo "$LINE" | awk '{print $2}'`
if ! mount -l -t nfs | awk '{print $3}' | grep -q "^$DIR$"
then
echo -n "Mounting '$DIR'"
COUNT=0
STOP=0
while [ $STOP -eq 0 -a $COUNT -lt 3 ]
do
if ping -qAc 3 $HOST > /dev/null
then
mount $DIR
STOP=1
echo " done."
else
# no sleep needed here because ping will take 3
seconds to fail anyway
COUNT=$( expr $COUNT + 1 )
echo -n "."
fi
done
if [ $STOP -eq 0 ]
then
echo " failed. $HOST not responding."
fi
else
echo "$DIR already mounted"
fi
done
