[solved] nfs mount hang

Hello everybody,

I hope here is somebody who can help me with my nfs mount issue. My raspberry pi (arch arm) is running a nfs server but I can't mount, it just hang forever.

I tried the following commands:

sudo mount -v -t nfs -o "tcp,vers=4" pi4:/ /mnt
mount.nfs: timeout set for Sun Oct 25 11:14:45 2020
mount.nfs: trying text-based options 'tcp,vers=4.2,addr=192.168.0.10,clientaddr=192.168.0.22'

and

sudo mount -v -t nfs -o "tcp,vers=3" pi4:/nfs /mnt    :(
mount.nfs: timeout set for Sun Oct 25 11:13:50 2020
mount.nfs: trying text-based options 'tcp,vers=3,addr=192.168.0.10'
mount.nfs: prog 100003, trying vers=3, prot=6
mount.nfs: trying 192.168.0.10 prog 100003 vers 3 prot TCP port 2049
mount.nfs: prog 100005, trying vers=3, prot=6
mount.nfs: trying 192.168.0.10 prog 100005 vers 3 prot TCP port 20048

I guess the server is running as expected:

showmount -e pi4
Export list for pi4:
/nfs 192.168.0.0/24

getent hosts pi4
192.168.0.10    pi4 pi4.crew

Running commands on the server:

/nfs            192.168.0.0/24(async,wdelay,hide,no_subtree_check,sec=sys,ro,secure,root_squash,all_squash)

And there is no active firewall on the raspberry pi and my computer.

Is anybody facing a similiar problem with nfs on arch linux?

Many thanks for hints.

Re: [solved] nfs mount hang

Time solves problems. Now everything works smooth. Seems that a full update of all involved systems (server, client, switch) solved the problem.
