Greetings,

I can no longer start my NFS server, which is rather problematic :x
Before I file a bug report, I wondered if anybody had encountered this issue, you can see the error returned when I start nfsd here:

Code:
# /etc/init.d/nfs restart
 * Stopping NFS mountd ...                                                                                                                                                             [ ok ]

(I was on gentoo-sources 3.10.7, I upgraded to 3.10.25 to check if this resolved the problem, it didn't ... )

I've also tried all combinations of NFS protocols (4, 4.1, 3 and 2) and nothing changes this behavior.

When I try mount an exported directory remotely, this is what happens:

Code:
# mount /usr/portage
mount.nfs: Connection timed out

Welp, I'm an idiot, figured out the solution, on the server:

Changed /etc/exports to:

Code:
# /etc/exports: NFS file systems being exported.  See exports(5).

/nfs            10.99.0.0/24(fsid=0,rw,no_subtree_check)
/nfs/portage    10.99.0.0/24(rw,nohide,insecure,no_subtree_check)


Then:

Code:

# echo "/usr/portage            /nfs/portage    none        bind                            0 0" >> /etc/fstab
# mkdir -p /nfs/portage
# mount /nfs/portage
# exportfs -r
# /etc/init.d/nfs restart


And it works once more, from the client:

Code:
# mount -t nfs 10.99.0.2:/nfs/portage /usr/portage
# df -h
Filesystem              Size  Used Avail Use% Mounted on
/dev/sda3                16G  9.6G  5.4G  65% /
tmpfs                   395M  968K  394M   1% /run
udev                     10M     0   10M   0% /dev
shm                     2.0G     0  2.0G   0% /dev/shm
cgroup_root              10M     0   10M   0% /sys/fs/cgroup
none                    1.0G   92K  1.0G   1% /tmp
none                    2.0G     0  2.0G   0% /var/tmp
10.99.0.2:/nfs/portage  1.8T  4.2G  1.8T   1% /usr/portage
