NFS & autofs problem

NFS & autofs problem

[Luca Ferrari]

Hi,
I've got two machines that exports the user's homes and other dirs with NFS, 
and the clients mount them via automount.
I've configured the client so that they can mount a directory from the main 
machine (main) or from the backup one (backup) if the main is not working. In 
other words, here there's an example of a client /etc/auto.home

* main,backup:/export/home/&

Now, I've got a question and a problem. The above file is valid also on the 
backup machine, that means I'd like the backup machine to mount directories 
from the main host, so that directories are always coming from one point. 
Nevertheless, the backup host mounts directories from itself, even if the 
auto.home is like the above. So the question is, how can I force the backup 
host to mount directories from main, and then from backup if main is down?

The problem, instead, is that clients are mounting directories from main and 
backup at the same time. In fact, I've shared another disk space, called 
shared, which autofs config file contains:
* main,backup:/export/shared/home/&

but when a user connects to a client, what happens is that the homes are 
mounted from main, while shared from backup. Now, I cannot see any difference 
in the configuration file, thus I cannot solve the problem. Any idea about 
it?

Thanks,
Luca

I solved the problem of the client mount thru weights, thus changing the 
configuration file of the client in one like the below:
* main(0), backup(10):/export/home/&

produces the right mount of the main machine and, if it is not available, of 
the backup one. However, I still don't know how to make the backup machine 
mounting the main one, instead of its local copy. Here the weights are not 
working.
