Question NFS share no longer mounting with errors


Hello,

I've got a fully updated Manjaro system (10.0.2.2 on my LAN) with an /etc/fstab that mounts remote NAS NFS shares (at 10.0.2.3 on the same LAN) with the following options: nfs intr,nolock,hard,rw,fsc 0 0

This has worked very well until about a week ago when the share stopped mounting automatically on boot. So I tried "mount -va" and got these messages:

Can someone help me troubleshoot this? What specifically can I do? Thank you.

Has anything changed recently such s a s/w or config update?

Have you a working rpcinfo program on this host, on another host?

Are you trying to use kernel modules that have not loaded for certain versions of NFS/RPC?

Is all your other networking in good order?

All other networking is working very well at the moment.

I have not made any modifications recently other than applying the standard Manjaro updates from their official repositories.

I don't know anything about rpcinfo or using kernel modules for certain versions of NFS/RPC...

Is rpcinfo something I should be using to troubleshoot this? Thanks!

Try with nfsvers=3 in fstab, perhaps NAS is not responding properly to NFSv4.
