Shouldn't it be 192.168.1.2:/ (excluding share name in case of NFSv4) or
has it changed?
Are you able to mount successfully if you just use the server name
like below:
mount -t nfs4 192.168.1.2:/ /mnt/test (in your case)

I'm also running a 11.2 RC1 and tried to mount nfs4 the way you
mentioned, but I don't see the hang you're observing:
mount -t nfs4 192.168.100.254:/export /mnt/nfs/
mount.nfs4: mounting 192.168.100.254:/export failed, reason given by
server: No such file or directory
Can you try to run mount with '-v' and post the output?

I'm not sure why you have two instances of idmapd.. Did you start idmapd
once again?

This is odd.

Have you enabled nfsserver during startup (chkconfig nfsserver on)?
