I've got an NFS server and several NFS clients, if I reboot the server, then when the client comes up (if the server is unavailable), I can get it to either skip the NFS mount or prompt me to ask how to continue.
However in man nfs it talks about a bg option, which should fork the mount to the background and retry the connection periodically (dmesg says every 90 seconds). When I try that, the client skips the non-existent server, but never seems to retry the connection when the server does come up.
How can I make it work? This is my fstab setting:
server:/var/www /var/www nfs rsize=8192,wsize=8192,timeo=14,intr,bg,retry=100,nobootwait 0 0
