shutting down

[Maurice Janssen]

Hi,

I have a few systems that are powered by the same UPS.  All of them are 
running nut; one system is connected to the UPS over the serial port 
(the 'master'), the others are talking over the network to the master 
(the 'slaves').

One of the slaves is acting as an NFS server and the master has a 
directory from the NFS-server mounted.

I'm wondering what will happen if the battery goes low and the NFS 
server will shutdown first.
Will the master shutdown normally, or will it stall while trying to 
umount the NFS share?  The slaves will shutdown first, so when the 
master goes down, the NFS server won't be responding.

The master doesn't have to wait for the NFS server, so umount -at nonfs 
would be fine.  Does this happen automatically or is there some way to 
configure this?


Thanks,
Maurice
