NFS problems

[Tim Hall]

I have an NFS server running on my Pi.  After a reboot this morning (an OSMC update caused it to hang, rebooting it fixed that), the client machine isn't mounting the exported drive. On rebooting the client machine, it took a suspiciously long time to get its arse in gear.

/etc/exports on the Pi has:

Code: [Select]

/media/Expansion_Drive 192.168.1.8(rw,sync,no_subtree_check,insecure)

/etc/fstab on the client machine has

Code: [Select]

192.168.1.2:/media/Expansion_Drive             /mnt/nas     nfs     defaults,user,auto,noatime,intr   0 0
The IP addresses are correct.

rcpinfo -p on the Pi has

Code: [Select]

Which suggests that all the relevant services are running on the Pi.  I've read a step by step guide to NFS with no avail.  Any clues welcome.

can the client ping the pi?
does the pi stil have the same address?
does the client still have the same address?
have there been any other changes to your network since the nfs server / client were last restarted?

Yes, yes, yes, not that I recall. Idiot operator (me) realises that Xubuntu (running on the client box) had a major update.
I can transfer files by ftp.

Having read up on a possible fix today, I got home and turned the box on, ready to get to grips with my fstab.  But It Just Worked anyway.
