Hello,
I'm back with these NFS problems
Server and client have been updated but it still rise time to time.
server is: Linux robin.legi.grenoble-inp.fr 3.10.0-1127.18.2.el7.x86_64
#1 SMP Sun Jul 26 15:27:06 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
client is : Linux grivola.legi.grenoble-inp.f
Hi Orion,
no, I still have this problem. I delay working on it as I the latest
updates have not been installed on the server and on the client. I'll
work again on this problem as soon as possible.
