Hello,
I just installed a 4 nodes webfarm (using direct routing).
a cron on each server check a file ($netconfig on GFS) like this :
if ! find $netconfig -anewer $netconfig | grep -q $netconfig ; then
echo "cluster node $node : $netconfig has changed, reconfiguring
network ..."
"$netsetup"
fi
So when I update the file, every server run $netsup. this is my way to
configure IP and arptables.
But as I know now, the atime is updated every hour. So my first option
would be to tune this to 60 instead of 3600. But I suppose that I will
have a perf issue ?? Do you have tips to handle that kind of scenario :
watch a file for modification ?
Thanks !
