I believe you want to put the 'bg' option into the list in /etc/fstab.
'bg' means background the mount if it would delay too long.
'soft' means return EIO (or some such) if, _after mounting_, you don't
get a response to a file service request.
John
from fstab(5):
mnt_opts specific to nfs (NFS) file systems (the
defaults are:
fg,retry=1,timeo=7,retrans=4,port=NFS_PORT,hard
with defaults for rsize and wsize set by the kernel):
...
bg if the first attempt fails, retry in the
background.
...
soft return error if server doesn't respond.
hard retry request until server responds.
The bg option causes mount to run in the background if
the server's mountd(8) does not respond. mount attempts
each request retry=n times before giving up. Once the
filesystem is mounted, each nfs request made in the
kernel waits timeo=n tenths of a second for a response.
If no response arrives, the time-out is multiplied by 2
and the request is retransmitted. When retrans=n
retransmissions have been sent with no reply a soft
mounted filesystem returns an error on the request and
a hard mounted filesystem retries the request.
