Without a functioning network, NFS just keeps trying to do the RPC.
This is normal behaviour for NFS and has been since 1985.
If you are using NFSv3 and want the I/O attempt to fail after a couple of
minutes instead of "just keep trying", you can use the mount options:
"soft,retrans=2". These options are not recommended for NFSV4.

Yep. At this point, the NFS client can do the RPC.
