NFS v4 problems maybe. Try setting a value for Domain in

That gave me an unbootable system. I've removed it, and am back at square 1. Two things -
I should have said that I can access the system from the laptop using ssh + keys.
During bootup I saw many messages about nfs4 exports failing, so that's
whre the problem is, it seems. Can you please give me a sample line
of a known good nfs4 export?
It's hard to be sure when messages flash by so quickly, but I got the impression that there was something about fstab. Maybe the format required for those lines has changed, too? These are the lines that I guess it is looking at:
/Data1 /nfs4exports/Data1 none bind 0 0 /Data2 /nfs4exports/Data2 none` bind 0 0 /Data3 /nfs4exports/Data3 none bind 0 0 /home /nfs4exports/home none bind 0 0
I think there was something about wrong or missing type. Each of those partitions is defined earlier in fstab and does have the correct type stated.
this is obviously intended to be your NFS server (who knows whether this is CentOS or Fedora 14).
The server is CentOS 6.
You can only bind mount something that already exists and maybe it's empty.
does ls -l /Data1 /Data2 /Data3 /home show much of anything?
Yes, it lists the contents of each of them.
On the other system (the NFS client), what does it have in fstab?
192.168.0.40:/Data1 /mnt/borg_Data1 nfs4 rsize=8192,wsize=8192,timeo=14,intr 0
0
and equivalents for each of the others.
As I said originally, these lines worked with nfs4 on CentOS 5.
then issuing the command (on the Fedora client)
mount /mnt/borg_Data1 should either work or fail and give you a message (at worst, log to /var/log/messages).
This of course assumes that it isn't already mounted which could be noted by simply issuing a 'mount' command by itself to see what is mounted.
You may have to check /var/log/messages on the CentOS server for clues too.
Every attempt to mount was simply hanging - so no help at all. However, as you will have seen by now, the problem is solved. I was right that I had missed some steps, and you were right that the mount points at the server end were not correctly set up. The guide on http://www.crazysquirrel.com/computing/debian/servers/setting-up-nfs4.jspx has got everything working again.
Thanks for trying to help.
