The /etc/exports configuration file for the server (named rg.local) has the line
The /etc/fstab configuration files for the clients have the line/home/pi *(rw,sync,no_subtree_check)
I can get 15 of the clients to connect to the server, but trying to connect a 16th machine hangs. I have checked that it does not matter which 15 connect.rg.local:/home/pi /mnt/g nfs defaults 0 0
I have increased the number of initial threads to 20 in the file /etcdefault/nfs-kernel-server but this has been of no help.
I have been trying to figure out why this is happening and I am stumped.
Does anyone understand what is causing this? Is there some limit set by SystemD, to manage resources?
After some research I found this issue occurs only in NFSv4.
