I created a mountpoint and an entry in the fstab
nas:/server1 /nas/server1 nfs rw,_netdev 0 0
This should try to mount the nfs during startup; but it might fail. That is why I also enabled the netfs daemon:
>sudo chkconfig
...
netfs 0:off 1:off 2:off 3:on 4:on 5:on 6:off
...
Current runlevel:
>runlevel
N 3
When rebooting, the mount does not work, not even after a while.
What can I do to troubleshoot this issue?
In /var/log/messages I only find one entry containing nfs.
Jun 7 16:14:51 bison kernel: RPC: Registered tcp NFSv4.1 backchannel transport module.
Jun 7 16:14:51 server1 kernel: Slow work thread pool: Starting up

This is the guide I tried to follow

[EDIT:]
I found more information, in the boot.log:
Mounting filesystems: mount.nfs: Failed to resolve server nas: Temporary failure in name resolution
So it seems the DNS is not working on boot-time. This makes sense, but I thought / assumed netfs would take take of this. However, I have been unable to find any netfs logging yet.
[EDIT 2]
netfs service was not running while it was configured in the chkconfig. Starting netfs (service netfs start) manually restored the missing mounts.
