Hi everyone,
I am experiencing an issue in the following circumstances:
os: rhel4.5
kernel client: 2.6.9-55.0.9.ELsmp
kernel server: 2.6.9-55.0.2.ELsmp
autofs version 4.1.3-199.3
server exports folder /nfs/folder with parameters:
async,rw,fsid=1,no_root_squash
client automounts /nfs/folder with:
auto.master:
/nfs /etc/auto.nfs
auto.nfs:
folder -fstype=nfs,udp,rsize=32768,wsize=32768,noatime
fs-cluster:/nfs/folder
default values for automount are --timeout 60
If I run a script that checks with a series of increasing sleep
intervals < 120 if an exported file is executable,
I notice that if there is a coincidence between an unmount request and a
file request the file test fails
Thu Oct 25 17:00:28 GMT 2007 Error at DELAY: 38
Oct 25 17:00:28 server mountd[8014]: authenticated unmount request from
client:989 for /nfs/folder (/nfs/folder)
Fri Oct 26 04:48:41 GMT 2007 Error at DELAY: 25
Oct 26 04:48:41 server mountd[8014]: authenticated unmount request from
client:846 for /nfs/folder (/nfs/folder)
the test script looks like this:
EXECUTABLE="/nfs/folder/somepath/exec"
DELAY="1"
STOPCOUNT=120
OUT=$1
while true
do
while [ "$DELAY" -lt "$STOPCOUNT" ]
do
test -x $EXECUTABLE
if [ "$?" -ne "0" ]
then
echo "$(date) Error at DELAY: $DELAY" >> $OUT
else
echo "$(date) Executable found at DELAY: $DELAY" >> $OUT
fi
sleep $DELAY
(( DELAY++ ))
done
done
any help is much appreciated
cheers,
Massimo
