When accessing a file in an ACFS file system from multiple nodes, stale attribute information may occasionally be returned from the stat() system call.


having node1 and node2 and an ACFS mounted on both nodes with mount point /opt/srv006/app

Executed the following on node1:

rm /opt/test/app/mgo/trazas/test.out
touch /opt/test/app/mgo/trazas/test.out
ssh node2 "echo 'Prueba' >> /opt/srv006/app/mgo/trazas/test.out"
if [ -s /opt/srv006/app/mgo/trazas/test.out ]
then echo "Test OK"
echo "Test KO "

The result of the test is always KO !!!!!!!

However, If I remove touch command the result is always OK !!!

And, If I do a sleep 10 for example before the if sentence,the result is also OK
